SentianceInsights-Control-TowerLegacy DocsImportant Security Notice

iOS

[6.14.0] - 17 Jun 2025

Added

  • A new canMonitorRegions SDK status property, to indicate whether monitoring iOS regions (geofences) is possible.

Changed

  • Improved the harsh driving event detection.

  • Improved the detection data syncing to support new backend capabilities.

  • SDK detections will now be paused (blocked) when iOS region monitoring is not possible due to exceeding the 20 regions per-app limit. See here.

Fixed

  • Fixed a rare issue where the SDK delays the app startup when using the synchronization SDK initializer.

[6.13.0] - 30 Apr 2025

Added

  • Support for omitting sensitive data (e.g. locations) from on-device insights uploaded to the Sentiance Cloud Platform.

Changed

  • Bumped the deployment target to iOS 13.0.

  • Improved the detection logic to avoid insignificant walking transports in the event timeline, where the user remains within a minimal distance.

  • Improved the detection of motorcycle crashes.

[6.12.0] - 28 Mar 2025

Added

  • Support for detecting and reporting car crashes with varying severity.

  • Severity information to vehicle crash events. See severity.

Changed

  • Improved phone handling detection under certain sensor conditions.

[6.11.1] - 4 Mar 2025

Fixed

  • An issue that resulted in a higher rate of false car crashes detections.

[6.11.0] - 28 Feb 2025

Added

  • A new isProvisional property to SENTTimelineEvent, which indicates whether the event is provisional. A provisional event is identified based on real-time detections, but may change in the near future as more data is collected and processed, to filter out unwanted artifacts. For example, a provisional car transport may get identified, followed by a provisional bus transport. After the full trip is complete, these provisional events may get merged into a single final car event. Currently, provisional events apply only to 'transport' types.

  • Provisional-aware event timeline API methods getTimelineUpdatesIncludingProvisionalEvents and getTimelineEventsIncludingProvisionalOnes, in addition to a new optional EventTimelineDelegate method onProvisionalAwareEventTimelineUpdate. You can use these to retrieve/receive all events, including provisional ones.

  • Provisional-aware user context API method requestUserContextIncludingProvisionalEvents, and the corresponding SENTUserContextDelegate method didUpdateProvisionalAwareUserContext. You can use these to retrieve/receive all events, including provisional ones.

  • The transportIsProvisional value has been added to the SENTOccupantRoleFeedbackResult enum. Submitting occupant role feedback for provisional transports is not allowed.

  • A new API for initializing the SDK in the background. See initializeAsyncWithOptions:launchOptions:completionHandler. This method must still be called on the main thread, inside application(_:didFinishLaunchingWithOptions:), however, it will internally offload the bulk of SDK initialization work to the background.

Changed

  • Improved the on-device transport mode detection algorithm. Real time transport events now undergo a post-trip reprocessing to refine and enhance the results. Consequently, transport events initially detected in real-time are subject to modification upon trip completion, and are classified as "provisional" until finalized. This change impacts your app if it relies on real time transport events. The following SDK APIs are impacted:

    • Event timeline: provisional transport events are not available via the existing APIs. Instead, use the new provisional-event aware APIs to receive them. See the "Added" section above.

    • Driving insights: driving insights are not available for a provisional transport, even upon the completion of the transport. Insights become available after the transport is finalized—typically, immediately after the entire trip is complete.

    • User's current context: provisional transport events are not available via the existing APIs. Instead, use the new provisional-event aware APIs. See the "Added" section above.

  • The minimum supported iOS version for SDK detections has been bumped from 13.0 to 15.0. When initializing the SDK on an unsupported iOS version, the initialization will fail with reason unsupportedOSVersion.

[6.10.1] - 7 Feb 2025

Fixed

  • Incorrect result type when requesting the average overall score via Objective-C.

  • Core data related stability improvements.

[6.10.0] - 31 Jan 2025

Upcoming Changes in the Next Release

Starting from v6.11, planned for the end of February 2025, the following changes will come into effect:

  1. Minimum supported iOS version for SDK detections will change from 13.0 to 15.0. You can still target iOS 13.0 for your app builds, however, detection will not be possible, and the SDK initialization will fail with reason SENTInitializationFailureReasonUnsupportedOSVersion.

  2. Objective-C integrations will no longer be supported for new SDK features/APIs. Existing functionality (introduced in v6.10 and earlier) will remain accessible via Objective-C, but new classes, methods, and properties will only be made available to Swift.

Added

  • A new driving insights feature for detecting the occupant role of the user during car transports (i.e. driver vs passenger). The occupant role is available at the end of a transport, in the SENTTransportEvent.

  • A feedback API, for providing feedback on the detected occupant role of the user during car transports. The feedback is used on the device to improve the accuracy of future detections. See submitOccupantRoleFeedback.

  • Support for assigning tags to transports. A tag is a key-value which can be assigned to an ongoing or future transport. The tag is included in the retrieved SENTTransportEvent, after the transport has ends. See setTransportTags.

  • Waypoints in phone usage, call-while-moving, and harsh driving events. These waypoints indicate the segments of the transport where the corresponding event occurred. Some waypoints can be synthetic, indicated by isSynthetic.

  • A driving insights API for retrieving the average 'overall' safety score of the user, over a period of the last 7, 14, or 30 days. See averageOverallSafetyScore.

  • Type and confidence information to harsh driving events. A type is categorized as acceleration, braking, or cornering.

[6.9.2] - 17 Jan 2025

Changed

  • The Sentiance SDK no longer invokes stopMonitoringSignificantLocationChanges and stopMonitoringVisits, in order to avoid disrupting the delivery of SLC and visit events to the enclosing app.

[6.9.1] - 26 Nov 2024

Fixed

  • Termination of the app due to failure to create a Core Data persistent store in rare situations. Now, when the primary store creation fails, the SDK initialization will fail with an appropriate error.

  • An issue that resulted in duplicate trips being reported on the Sentiance Cloud Platform.

[6.9.0] - 4 Oct 2024

Added

  • An array of NSErrors to the SDK initialization result (SENTInitializationResult), which holds the errors that were encountered when the SDK initialization fails due to internal inconsistency or error. For troubleshooting purposes, it is recommended to log or store these errors.

Changed

  • Improved the detection of public transport modes, with the help of public transport route information (e.g. train and bus routes), which gets stored on the device and utilized offline.

  • Updated TensorFlowLiteC dependency to v2.17.0. If you are using Sentiance's custom-built TensorFlowLiteC framework for ARM simulator support, please update your Podfile to remove the entry targeting the custom TensorFlowLiteC pod.

Fixed

  • Stability improvements to the lifestyle insights feature (e.g. user segments, venue-type identification).

  • Appstore submission error when building with Xcode 16, due to the inclusion of bitcode in mpde and dskoball SDK dependency frameworks. Bitcode has now been removed from these frameworks.

[6.8.6] - 30 Sep 2024

Fixed

  • Occasional high battery usage, caused by an ongoing location update request, when the Smart Geofences feature is activated.

[6.8.5] - 23 Sep 2024

Added

  • Support for remotely tuning the overall safe driving score.

Fixed

  • Fixed an issue that caused missed detection of phone usages while driving.

[6.8.3] - 9 Aug 2024

Fixed

  • An issue that resulted in an 'overall' safe driving score of Nan (not a number).

[6.8.2] - 2 Aug 2024

Changed

  • Unified the Driving Insights "overall safety score" formula across all transport types.

[6.8.1] - 15 Jul 2024

Fixed

  • Crash during SDK initialization, when checking for protocol conformance of a Swift class that is defined in the app.

  • Occasional crash caused by Core Data related EXC_BAD_ACCESS exception.

  • A rare issue where the termination of a phone call during a transport is not properly registered, thereby negatively impacting the transport's call-while-moving score.

[6.7.4] - 8 Jul 2024

Fixed

  • Crash during SDK initialization, when checking for protocol conformance of a Swift class that is defined in the app.

[6.8.0] - 5 Jul 2024

Added

  • Smart Geofences feature. You can use Smart Geofences to monitor points of interest, and get notified of entries and exits. See here about the feature and its build dependencies, and here for some sample code.

Changed

  • Improvements to the transport classification of public transport modes.

  • SDK files are now excluded from iOS backups by default. The SENTExcludeSentianceFilesFromBackup flag previously added in v6.7.3 can be omitted.

Fixed

  • App validation issues on the App Store, when using Xcode 15.3 and later.

[6.7.3] - 6 Jun 2024

Added

  • Support for excluding new SDK files from being backed up by iOS. To enable this, add the key SENTExcludeSentianceFilesFromBackup to your app's Info.plist, with the value YES. Note that starting from version 6.8.0, backup exclusion will be the default behaviour, regardless of the presence of this key.

[6.7.2] - 3 May 2024

Fixed

  • An internal deadlock, causing the SDK initialization to get stuck indefinitely.

[6.7.1] - 15 Apr 2024

  • A new isLocationAvailable SDK status property, to reflect the SDK's view of accurate location availability.

Changed

  • Improved the runtime performance of the following sensor processing features: crash detection, transport classification, harsh driving detection, and phone usage detection.

  • Updated the SDK's framework folder structure to address asset validation issues on Xcode 15.3.

  • Updated the Objective-C Protobuf framework that is bundled in the Umbrella framework, and referenced by the Sentiance SDK SPM package, to v3.18.3-p. This is a Sentiance-packaged framework using the official v3.18.3 source code, with an added privacy manifest file. It has a minimum iOS version set to 10.5.

[6.6.4] - 18 Mar 2024

Added

  • Privacy manifest file to the Sentiance SDK. Note: a manifest file has also been added to the Protobuf SDK that is bundled in the Umbrella framework, and the one shipped with the Sentiance SPM package. For CocoaPods integrations, updating to Protobuf v3.25.3 from the official source is sufficient to include the Protobuf manifest file.

Changed

  • Increased the capacity for storing downloaded speed limit data.

Changed

  • Driving insights: updated the minimal transport distance and duration requirements for safety score calculation, to 500 meters and 3 minutes respectively.

  • Rearchitected the SDK's background task execution component to utilize only one iOS background task. As such, only the following background task identifier is needed in the Info.plist: com.sentiance.backgroundtask.task_processing

Fixed

  • Under certain circumstances, the starting location of a trip is incorrectly chosen to be an older stationary.

  • Potential crash at runtime, if the SDK is initialized after having been reset in the same lifetime of the app process (i.e. without an app restart).

[6.5.2] - 11 Dec 2023

Fixed

  • Occasional crash when creating a user, after having reset the SDK.

[6.5.1] - 9 Nov 2023

  • Legal driving safety score, which is computed using the traveled speed information during vehicular transports, in addition to the use of speed limit information that is downloaded and stored offline by the SDK. Corresponding speeding events can be retrieved via the Sentiance API.

  • Overall safety score, which is computed using the other safe driving scores.

Changed

Fixed

  • Stability improvements to the underlying movement detection algorithm.

[6.4.0] - 10 Jul 2023

Production Readiness Update

In this release, the following features have been promoted from Early Access to Production Ready:

  • Transport classification

  • Home & work detection

  • User segment detection

  • User's current context information

See our On-Device Features page for more information about these features. Detailed overview of feature production readiness can be found on this page.

This version includes breaking changes for some Early Access features.

Breaking

Added

  • Phone usage detection during vehicular transports. This feature is part of the on-device Driving Insights feature. It uses a custom machine learning model to accurately detect phone usages. The detected events can be obtained using the getPhoneUsageEvents.

  • Focused driving safety score, which is calculated by taking into account the detected phone usage events during vehicular transports. See SENTSafetyScore.

Fixed

  • Stability improvements to the movement detection subsystem.

  • Improvements to the on-device home and work location detection.

  • Runtime warnings about the usage of NSKeyedUnarchiveFromData.

  • Rare crash caused by blocked the main thread during SDK initialization.

  • Excessive device storage usage during the lifetime of the SDK.

  • Compile time warnings about category method overriding a class method.

[6.3.3] - 21 Jun 2023

Fixed

  • Stability fixes to the home/work detection and venue-type mapping features.

[6.3.2] - 8 May 2023

Fixed

  • Stability improvements to home and work venue detection.

[6.3.1] - 18 Apr 2023

Fixed

  • Runtime exception when using the TransportSession feature.

  • A bug introduced in v6.3.0, which delayed the SDK's reaction to location permission changes.

[6.3.0] - 7 Apr 2023

This version includes breaking changes for some Early Access features.

Added

  • A new Driving Insights feature, which provides information about a user's driving behaviour. In this first version, the SDK detects harsh driving events (e.g. acceleration, braking, and turning), which are then used to compute a vehicular transport's smooth driving score. This data is available via the new APIs in the Sentiance class, which allows the subscription to, and retrieval of DrivingInsights and HarshDrivingEvents. This feature must be enabled by Sentiance before use.

  • New API methods in the Sentiance class which allow the subscription to, and retrieval of TransportSessions. A transport session corresponds to a transport that was detected by the SDK, and includes information such as the mode of transport, and the raw sensor data that was used to classify it. This API is primarily intended to be used for accessing the raw sensor data. To simply be notified of new transports, it's more efficient to utilize the UserContext info.

  • A short history of locations inside SENTVehicleCrashEvent, which represent the preceding locations leading up to the crash event.

Fixed

  • Several minor stability issues.

Removed

  • BREAKING: a number of user segments that are no longer supported.

[6.2.5] - 9 Mar 2023

Fixed

  • distanceInMeters property of TransportEvent returns nil instead of a proper result.

[6.2.4] - 16 Feb 2023

Fixed

  • Incorrect device low-power-mode indicator when checking the SDK status. This bug also impacted the system API result when calling ProcessInfo.isLowPowerModeEnabled.

[6.2.3] - 9 Feb 2023

Fixed

  • An exception caused by deadlocking logic, when checking the background app refresh status and device thermal state.

[6.2.2] - 31 Jan 2023

Fixed

  • An exception related to incompatible bundled models, caused by build-time SDK Bundle merge by Xcode.

  • An issue where the SDK would start running in the background without detections being started, due to a conflict with a geofence set at the app level.

  • An exception caused by deadlocking logic, when checking if the device is in low power mode.

[6.2.1] - 19 Jan 2023

Removed

  • CocoaPods: $(PODS_ROOT)/** path from SWIFT_INCLUDE_PATHS that was being set by the SDK Podspec configuration. This was resulting in build errors when compiling Swift files.

Fixed

  • High CPU usage when some on-device features were enabled, such as User Segment Detection and Stationary Venue-Type Mapping.

[6.2.0] - 9 Jan 2023

This version includes breaking changes for some Early Access features.

Added

  • Transport waypoint and distance information to SENTTransportEvent, which is part of the event list returned in SENTUserContext. Both waypoints and distance are based on unprocessed (i.e raw) location data.

  • User's current semantic time info to SENTUserContext (e.g. morning, lunch, evening). See SENTSemanticTime.

  • A new multi-purpose SDK background task, with identifier com.sentiance.backgroundtask.task_processing. Adding this identifier to your app's Info.plist is mandatory. Please update your project settings, and enable Background fetch and processing capabilities.

  • isDeviceLowPowerModeEnabled property to SENTSDKStatus, to indicate whether the device is in low power mode.

  • isMotionActivityPermissionGranted property to SENTSDKStatus, to indicate whether the motion activity permission has been granted.

  • Support for uploading additional SDK status information to the Sentiance Cloud Platform.

  • New SDK dependency called dskoball. See dependencies.

Changed

  • Stationary venue mapping has been update to an improved version, but that is limited to venue-type mapping. i.e. a stationary will no longer reference a specific venue, but a venue type instead.

  • Improved support for on-device user segment detection.

  • The SDK's background task identifier com.sentiance.backgroundtask.segment_detection is no longer required. You may remove it from your app's Info.plist file.

  • Disabled SDK logging to the device system log (i.e. console).

Fixed

  • Rare exception when uploading logs to the Sentiance Cloud Platform.

Removed

  • BREAKING: SENTUserContextUpdateCriteriaActiveMoments criteria type.

  • BREAKING: SENTMoment class. SENTUserContext no longer returns moments.

  • BREAKING: venueSignificance is removed from SENTStationaryEvent, and moved to SENTVenue. SENTStationaryEvent now references a SENTVenue.

  • BREAKING: SENTVenueCandidates and SENTVisit classes are removed. venueCandidates has been removed from SENTStationaryEvent.

  • BREAKING: SENTVenue now has a nullable location, which previously was not nullable. The location can be nil when it's unknown, such as when a stationary has a venue significance of "point of interest". In this case, only the venue type is known, but not its exact location.

  • BREAKING: SENTVenue no longer has venue name or labels.

[6.1.3] - 1 Dec 2022

Fixed

  • Runtime exception when processing a detected stationary for venue mapping purposes.

  • Diagnostic API for monitoring vehicle crash detection. See setVehicleCrashDiagnosticHandler:

  • App-configurable rules to control SDK data transmission to the Sentiance Cloud Platform. The app can specify which of the following data types are allowed to be transmitted to the Sentiance platform: vehicle crash data, SDK and device info, general detection data, all data. See setTransmittableDataTypes:

  • Support for car, bus, train, and tram/metro transport mode detection, part of the user's current context information.

  • Internal support in the SDK to notify the Sentiance Cloud Platform that the SDK has been reset.

  • Support for specifying 'any' trip type when calling isTripOngoing: using SENTTripTypeAny.

Fixed

  • Improve the detection of vehicle crashes that occur towards the end of a trip.

  • Rare occurrence of a EXC_BAD_ACCESS crash.

  • File operation exception at runtime, causing the process to crash.

  • Inaccurate stationary venue information in some instances.

Removed

  • BREAKING: vehicle and rail transport modes from the user's current context information.

  • Fixed TensorFLowLite model updating mechanism at runtime.

  • Removed embedded TensorFlowLite library from SENTSDK pod by providing a separate thinned package and adding a pod dependency to TensorFlowLite (applies to CocoaPods integration only and requires CocoaPods 1.10.0 or above).

[5.11.0] - 16 Jul 2021

Added

  • Support SDK artifacts without CallKit linkage

Fixed

  • Fixed rare and transient runtime crashes when object references inside the SDK get released from the OS due to erroneous reference semantics.

  • Fixed delayed uploading of payloads in case of outdated authentication tokens.

  • Fixed missing trip detections due to erroneous flip flop checks.

[5.10.1] - 20 May 2021

Changed

  • Updated embedded TensorFlowLite framework to v2.4.0.

Fixed

  • Fixed potential accelerometer data gaps in trip objects due to included data from previous trips.

  • Fixed swift compiler warning since Xcode 12.5 wrt a missing include in the umbrella header.

[5.10.0] - 14 Apr 2021

Added

  • Support for approximate location access available since iOS 14.

  • Support for detection of screen lock/unlock events.

Changed

  • Add fail-fast mechanism during third party user linking if linking has not been completed.

  • Slightly adjust the actual stationary start time in the same way as the Android SDK.

Fixed

  • Missing sensor data for crash events in some cases.

  • Overlapping stationary events in case of trip timeouts.

  • Recovery of trip object creation in case the SDK got killed by the OS.

  • Trip object creation and submission in case of a crash event.

[5.9.0] - 29 Jan 2021

Added

  • New type to SDK artifacts which are now packaged as both Framework and XCFramework (Please make sure to have CocoaPods 1.10.0 or above installed on your machine if you integrate Sentiance SDK via CocoaPods).

  • An improved and more accurate vehicle crash detection, backed by a machine learning model. You must switch to using the new Sentiance API method setVehicleCrashHandler: to activate it.

  • A new method to help test your crash detection integration. See invokeDummyVehicleCrash.

  • A new method to check if crash detection is supported on the device for a specific trip type. See isVehicleCrashDetectionSupported:.

Beta Feature: Support for host apps that enable Data Protection. This functionality is released as a beta feature and not yet recommended for production use.

Changed

  • The trip serialization process utilizes a less intense and more optimized background processing model.

Deprecated

Fixed

  • An issue where portions of accelerometer and gyroscope data might be missed

  • An issue where stationary detection might overlap with past stationary and trip detections

  • An issue where the SDK might continuously report an initialization state of SENTInitInProgress after the initialization credentials are changed

  • An issue where the SDK might continue collecting location fixes even after the user becomes stationary and cause excessive energy consumption

  • An issue where the SDK might accidentally remove keychain items owned by the host app

  • An issue where the SDK might crash during a network operation

Removed

  • Location permission prompt when starting the SDK. If you rely on the SDK for prompting the user, please make sure you update your app and prompt the user during the onboarding.

Changed

  • The geo-fence management policy so that the SDK does not intervene with the lifecycle of geo-fences owned by the enclosing app.

  • Removed the motion activity permission prompt when starting the SDK. If you rely on the SDK for prompting the user, please make sure you update your app and prompt the user during the onboarding.

Fixed

  • An issue where the SDK database might experience conflicts when the enclosing app also uses database instance(s) of CoreData.
