iOS Changelog

Version 6.3.1 (2025-05-08)

  • Improved: Fixed an issue with data transmission.

Version 6.3.0 (2025-04-29)

  • Added: Optimized transmission logic for short-lived token payloads to reduce latency and enhance reliability.

Version 6.2.1 (2025-01-13)

  • Changed: Renamed func handleEvents(forBackgroundURLSession: identifier, completionHandler: completionHandler) to processBackgroundSessionEvents(with identifier: String, completionHandler: @escaping () -> Void).
  • Changed: Updated func clearData() -> Int to replace the previous implementation clearData(completionHandler: @escaping () -> Void).
  • Improved: Thorough error message reporting on the delegate method func dataUploadWithTracked(from startDate: Date, to endDate: Date, didCompleteWithError error: Error?).

Version 5.2.0 (2024-08-26)

  • Improved: Enhanced collection and upload of data.
  • Removed: isLocationServicesEnabled property.

Version 5.1.7 (2024-04-01)

  • Fixed: Occasional incomplete transmission on switching off tracking.

Version 5.1.1 (2024-02-16)

  • Added: Swift Package Manager (SPM) support.

Version 5.0.5 (2023-10-16)

  • Improved: Load the CoreData layer asynchronously.
  • Improved: Maintain the original device id on a different JWT, if it's on the same UUID.
  • Added: Beacon monitoring for certain clients, requiring the NSBluetoothAlwaysUsageDescription in your app's Info.plist.

Version 5.0.0 (2022-10-17)

  • Added: hasRequiredPermissions: Bool { get }. True when both location services are enabled and app location permissions are authorized.
  • Added: isLocationServicesEnabled: Bool { get }. True when location services are enabled.
  • Added: version: String { get }. SDK version.
  • Removed: delegate property setter/getter.
  • Changed: The SDK must be initialized by calling the new initialize(using delegate: MotionTagDelegate, launchOption launchOptions: [AnyHashable : Any]?) function.
    The initialization should still happen somewhere near the top of didFinishLaunchingWithOptions App's delegate. Calling any other SDK function or property prior to its initialization will result in an error.
  • Changed: func trackingStatusChanged(_ isTracking: Bool)
    and func locationAuthorizationStatusDidChange(_ status: CLAuthorizationStatus, precise: Bool) methods of the MotionTagDelegate are required. Also, both are called upon initialization.
  • Changed: userToken is an optional since it's initially nill before setting. Not setting it with a valid JWT token will cause a transmission failure.
  • Changed: wifiOnlyDataTransfer is now false by default.

Version 4.3.1 (2022-08-16)

  • Improved: Add SDK to CocoaPods trunk. Simply do: pod 'MotionTagSDK'. No need for the github link.
  • Changed: Increase minimum target version to 12.3

Version 4.3.0 (2022-02-24)

  • Improved: Improve the accuracy of detected stays
  • Fixed: Fix a rare crash during the background data transmission

Version 4.2.1 (2022-02-03)

  • Added: Apple Silicon build for iOS simulator

Version 4.2.0 (2021-11-17)

  • Fixed: Fix an issue where Xcode 13 archiving process would wrongly overwrite the SDK's internal version and build numbers.
    • We recommend Xcode 13 users to update to SDK 4.2.0 or later, or disable the "Manage Version and Build Number" in Xcode. If you use fastlane, you can set manageAppVersionAndBuildNumber to false.
  • Fixed: Fix an edge case where tracking is switched off after revoking location authorization

Version 4.1.0 (2021-10-12)

  • Improved: Reduce gaps in the detected stays
  • Fixed: Fix an issue that could prevent data from being transmitted after the app is migrated to a new iPhone
  • Fixed: Fix rare crashes during the data transmission

Version 4.0.0 (2021-08-09)

  • Changed: The useWifiOnlyDataTransfer method has been replaced by property wifiOnlyDataTransfer.
  • Changed: The token parameter has been dropped from the start method.
  • Changed: The sharedInstance(...) method has been changed to a property.
  • Changed: Delegate didTransmitData(_ transmissionTimestamp: Date, lastEventTimestamp: Date) is replaced with dataUploadWithTracked(from startDate: Date, to endDate: Date, didCompleteWithError error: Error?), showing the timestamp of the earliest and latest events in the batch, as well as any possible transmission errors.
  • Added: Property userToken that allows updating the user JWT during runtime (e.g.: when the token expires). The provided token will be persisted in the SDK and must be provided before calling the start() method. This property can also be used to retrieve the set token.
  • Removed: The settings dictionary has been dropped altogether.
  • Removed: The battery saving mode option has been removed. Battery saving mode is always enabled now.
  • Removed: The isTrackingActiveAsInt property has been dropped.
  • Fixed: Fix background task leak.

This commit in the sample app repository demonstrates how to update from version 3.x.x to 4.0.0.
