Fixed an issue where detections were not able to start on iOS 15 devices due to the updated authorization status.
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).
Support SDK artifacts without CallKit linkage
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Fixed delayed uploading of payloads in case of outdated authentication tokens.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.
Updated embedded TensorFlowLite framework to v2.4.0.
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.
Support for approximate location access available since iOS 14.
Support for detection of screen lock/unlock events.
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.
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.
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
A new method to check if crash detection is supported on the device for a specific trip type. See
The trip serialization process utilizes a less intense and more optimized background processing model.
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
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.
The SQLCore I/O database error
High frequency GPS configuration
An issue where the SDK might not register geofences after determining that the user is stationary
An issue where the SDK might use outdated geofences during stationary state determination
An issue when using beacon regions was causing unexpected exits
Support added for on-device trip profiling and hard event detection.
An issue where the SDK might quit unexpectedly during resetting due to an internal issue
Support for resetting the SDK to factory settings, which clears all user data and allows creating a new Sentiance user.
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.
An issue where the SDK database might experience conflicts when the enclosing app also uses database instance(s) of CoreData.
Fixed the SDK start/stop infinite loop when the user was selecting “Allow Once” for iOS 13 location permission.
