Release Notes

Below is a complete list of changes for each release of the Tealium for Swift library.

1.9.0 - 1.9.7 (2020)

1.9.7 (September 2020)

Low Impact Changes

• Moved a process within the Remote Commands Module to a background thread
• Updated some of the concurrent queues to serial queues to prevent deadlocks

1.9.6 (July 2020)

Low Impact Changes

• Fixed a bug causing crashes due to multiple threads trying to save to a persistent data store at the same time.
• Fixed a bug causing crashes if the Tag Management module was included as a dependency, but not enabled via the Mobile Publish Settings in TiQ.

1.9.5 (June 2020)

Low Impact Changes

• Fixed a bug that caused crashes if the Remote Publish Settings feature is enabled, and the remote file contained non-standard content. Unit tests added to prevent this bug reappearing in future releases.
• Added unit tests to the public repo.
• Removed legacy code comments referencing UIWebView.

Known Issues

• For iOS versions 10.3.3 and 10.3.4, there is an Xcode compiler bug that may cause a crash as soon as the app is launched. This affects 32-bit iOS devices (iPhone 5C and below and iPad 4th gen and below). The workaround is to change the “Dead Code Stripping” build option to “NO”. This is located in Project Settings > (Your app target) > Build Settings > Linking > Dead Code Stripping. This workaround is only required if you are targeting the devices mentioned above.

1.9.4 (April 2020)

Low Impact Changes

• Fixed an issue affecting Carthage builds where the PLCrashReporter dependency caused a build failure on some platforms
• Fixed a bug where the remote commands module occasionally triggered commands multiple times if remote publish settings was enabled
• Fixed an issue where SwiftUI previews would fail if the library was installed via Swift Package Manager for any platform other than iOS

1.9.3 (March 2020)

Low Impact Changes

No functional changes. Fixed an issue affecting Carthage builds for the macOS platform.

1.9.2 (March 2020)

Low Impact Changes

• Fixed a bug in the DispatchQueue module, which resulted in a crash if the maximum queue size was set to -1
• Updated PLCrashReporter dependency

1.9.1 (February 2020)

Low Impact Changes

This version did not change any functionality. The version number was bumped to 1.9.1 to fix an issue with the Carthage dependency manager. No other changes were made.

1.9.0 (February 2020)

New Features

• Support for Mobile Publish Settings

Mobile Publish Settings are enabled by default, and must be disabled if you don’t wish to use them.

* Adds the ability to remotely change certain configuration options, such as event batch size, from the Tealium iQ Mobile Publish Settings interface.

• This matches the functionality already present in Tealium iOS (Objective-C) and Tealium Android libraries. Learn more.
• Swift Package Manager support. Learn more.
• Swift 5 support
  • Support for older Swift versions has been removed. If you are unable to use Swift 5, then use Tealium Swift 1.8.2.
  • It is no longer required to bundle the Swift runtime with your app if you are using Swift 5+. This significantly reduces the size of your app bundle by approximately 40MB.
• Mac Catalyst support
  • Supports iOS apps that are enabled to run on macOS Catalina (10.15+)
• Lifecycle tracking methods are now available as part of the public API. Learn more.
• Optional location tracking module. Learn more.
• List of enabled modules now added to each track request. For example, enabled_modules=["attribution","tagmanagement"].

Low Impact Changes

• Bug fix: Attempt to fix an un-reproducible bug in the Lifecycle module that occasionally causes crashes in low memory scenarios. 120
• Lifecycle auto-tracking may now be disabled. This option suppresses automatically-generated app lifecycle events. Learn more
• Removed dependency on Objective-C NSError for the Core module. Required for Swift Package Manager support. Also fixes implicit import of bridging header issue. 125
• Optimized Tealium.update method. Modules are no longer deinitialized and reinitialized when the update method is called to change the TealiumConfig settings

High Impact Changes

• Setters and getters on the TealiumConfig class have been deprecated in favor of properties. For example, config.setBatchingEnabled(true) -> config.batchingEnabled = true. Setters and getters continue to function as expected, but we recommend switching to properties to avoid compiler warnings.
• Added “wifi only sending” option, which is controllable through Mobile Publish Settings. If enabled, hits are queued unless wifi is available.
• Added “battery saver” option, which is controllable through Mobile Publish Settings. If enabled, hits are queued if low power mode is enabled, or if the device has less than 20% battery remaining

Known Issues

• There is currently a WebKit bug, which results in spurious error messages in the LLDB console when you are debugging your app. The error is similar to the following example:

2020-01-23 11:48:37.219410+0000 TestApp[853:82765] [Process] kill() returned unexpected error 1

This error appears if you are using the Tag Management module, until Apple fixes the issue in the WebKit library. Learn more.

1.70 - 1.8.2 (2019)

1.8.2 (December 2019)

Low Impact Changes

• Fixed thread-related Remote Commands crashes 121
• Reduced stored lifecycle sessions to 20 sessions to resolve low-memory related crashes 120
• Fixed some retain cycles that would in some cases prevent a total deinit of the Tealium class
• Added a removeInstance method to the TealiumInstanceManager to allow total deinit of Tealium
• Added config option to not use the cookie observer for WKWebView 117 (config.shouldAddCookieObserver = false)
• Optimized module initialization so that init is only called on modules that are present in the modules list.
• Fixed an issue where the Tag Management completion did not receive expected details (errors/info). Related to: 118

1.8.1 (November 2019)

Low Impact Changes

• Fixed a bug that caused an occasional crash in the Tag Management module

1.8.0 (November 2019)

New Features

• Event batching
  • Send up to 10 events in a single hit to the Tealium Customer Data Hub
    • For Tag Management, events are dispatched to the WKWebView instance in a batch and are processed individually by JavaScript tags in your profile.
    • For Tealium EventStream/AudienceStream/Event Data Framework products, events are dispatched in a single HTTP request when using the Collect module. Requests are Gzipped. Once the event limit is reached (max 10 events), they are dispatched immediately, if a connection is available.
  • To disable event batching, set the batch size to 1
• Optional Visitor Service module (requires AudienceStream CDP). Retrieve visitor profiles in real-time as soon as the profile changes.
• New variable "device_type" that captures the internal device identifier, for example iPhone8,4.
• Additional header docs for Visitor Service and Event Batching (DispatchQueue module).
• Added ability to override both the URL and profile for the Visitor Service module
• Fixed a possible crash on iOS 12.0 devices in the DeviceData module, which was due to a known bug in the iOS 12.0 network subscriber information API. Bumped version check to iOS 12.1 where the bug was fixed, and fall back to older API for iOS 12.0
• Added some additional hints for the compiler inside complex closures to allow the project to be built on Xcode 10.3.
• Added remote_api call for future Remote Command compatibility. This triggers an additional call to the Tag Management webview (if module enabled). Disabled by default. Config option to enable: config.setIsRemoteAPIEnbled(true)
• Added method to retrieve visitor ID

High Impact Changes

• Persistent Storage has now moved from UserDefaults to JSON-based file storage. Data is stored by default in the caches directory on the device, but this is overridable through config.
• Where possible, all processing is now performed on a background queue. If you are using the Tag Management module, a limited amount of processing is performed on the main thread, as this is a requirement for WKWebView.
• The following modules have been removed:
  • FileStorage (superseded by DiskStorage, which is part of Core)
  • DefaultsStorage (superseded by DiskStorage, which is part of Core)
  • DataSource (incorporated into VolatileData module)
• Tag Management Optimizations (Webview)
• UIWebView has been removed. Default is now WKWebView (only if using the Tag Management module). Due to bugs in the WKWebView API for iOS versions <11, cookies may not be persisted on these devices when upgrading to 1.8.0 from earlier tealium-swift versions.
• vdata dispatcher removed. All Collect module requests are now sent as POST requests to the /event endpoint, or /bulk-event in the case of batched requests
• Connectivity checks improved.
• Connectivity crash fixed (TealiumRepeatingTimer deinit)
• Updated project to work with Xcode11
• Crash reporter dependency fixed (currently using a binary build of PLCrashReporter until a fix is available)

Low Impact Changes

• Attribution module updated to include additional data points provided by the Apple Search Ads API
• DeviceData module device names updated to include latest Apple devices
• Logging improvements
• Swiftdoc improvements; all public methods now have quick help available in Xcode

1.7.3 (November 2019)

Low Impact Changes

• Fix for PLCrashReporter dependency with Xcode 11. Now uses a pre-built framework instead of building from source.

1.7.2 (August 2019)

Low Impact Changes

• Minor internal change to support unit testing for Remote Commands.

1.7.1 (July 2019)

High Impact Changes

• UIView auto-detection logic for WKWebView has been improved, which accounts for most cases with complex view hierarchies, without the need to manually pass a UIView instance in the webview config. Validation in your own app is essential; verify that you see tracking calls leaving your app in a variety of different screens in your app, including any views that may be launched from push notifications, where the view hierarchy may have changed.

1.7.0 (May 2019)

High Impact Changes

• TagManagement Module now uses WKWebView instead of UIWebView by default. Read tag management documentation carefully before upgrading.
• Consent Manager: If consent logging is enabled, a "decline_consent" event is sent for auditing purposes (GDPR compliance).

Low Impact Changes

• Bug Fix: In remote commands, fixed an issue where callbacks to the web view were not executed.
• Sample apps updated to be compatible with Xcode 10.2.
• New feature: Trace. Provides an easy method to join and leave an AudienceStream trace session, including terminating an active visitor session.
• New sample app showing how to use TagManagement with complex view hierarchies.
• Data layer variable standardization (see Data Layer for full list).

1.50 - 1.6.7 (2018)

1.6.7 (December 2018)

• Reintroduced init completion with module responses. Tealium is guaranteed to be initialized, along with all modules, when the completion block is called.
• Completion is only called once.
• Subsequent reloads of the TagManagement webview (if enabled) no longer causes remote commands to be re-enabled.
• VolatileData getData() method with no arguments has been reintroduced.

1.6.6 (December 2018)

Low Impact Changes

• Fix to enable usage of DeviceData module in app extensions (extension-safe access to UIApplication.shared).

1.6.5 (November 2018)

High Impact Changes

• Full modularization of library components; import only the modules you require.
• CocoaPods module import changed from tealium_swift to TealiumSwift.
• Minimum supported Swift version is now 4.0 due to Swift 3.X deprecation in Xcode 10. 1.6.4 is the last version supporting Swift versions <4.0. Use this if you require support for Swift 3.2.
• Core: Module responses removed from completion closure for simplicity
• TealiumConfig: TealiumModulesList is no longer required if you are only importing the specific modules you require. It continues to function as expected if present.
• TagManagement Module: With iOS 12, a memory leak has been introduced into the UIWebView API. This is out of Tealium’s control and has been logged with Apple. Rest assured, this is a small leak, and does not impact your app in any significant way, but it shows up when profiling your app with the “Leaks” instrument. The leak disappears with a future iOS update, once Apple has fixed the issue. Learn more. If you do not need the tag management feature, you may remove the TagManagement module from your build to not experience this leak.
• Remote Commands: Add remote commands via the TealiumConfig instance, rather than the public API method exposed on the Tealium instance. Learn more about the RemoteCommands module.

Low Impact Changes

• Core: Improved library startup time.
• CrashReporter Module: Reintroduced the Crash Reporter module following Xcode 10 fixes.
• VolatileData Module: Fixed bug causing timestamps from queued hits to be overwritten.
• VolatileData Module: Added event_timestamp_unix, which is a second-precise 1970-epoch timestamp.
• TagManagement Module: Nested objects now supported.
• TagManagement Module: Memory leak fixes.
• RemoteCommands Module: Fixed a bug causing the Remote HTTP command to occasionally not be called when invoked.
• PersistentData Module: Bug fix for potential memory leak.
• Lifecycle Module: Fixed a bug that occasionally caused crash data to persist across more than 1 event, potentially causing inflated crash metrics in analytics reports. Crashes are now only sent on “launch”.
• DeviceData Module: network_connection_type now moved to Connectivity module to remove unnecessary dependency.
• DeviceData Module: Add app_orientation and app_orientation_extended to indicate the orientation of the app, as well as existing device_orientation and device_orientation_extended.
• Delegate Module: Tealium completion handler moved to TealiumCore framework.
• Connectivity Module: Set a default time to flush the queue of 30 seconds while the device is known to be offline.
• Connectivity Module: Added protection around timer code for connectivity check.
• Attribution Module: Removed unnecessary code for Swift versions <4.0 (no longer supported due to Xcode deprecation of Swift 3).

1.6.4 (October 2018)

Low Impact Changes

• Minor fix to make TealiumRemoteCommand class accessible when using CocoaPods/Carthage (access level changed from public to open).

1.6.3 (October 2018)

Low Impact Changes

• Removed “always embed swift binaries” from targets.

1.6.1 (September 2018)

High Impact Changes

• Fix for session ID; Tealium Session ID set to expire after 30 minutes. This value is configurable.

1.6.0 (July 2018)

• High Impact Changes
  • Initial release of Consent Manager module. This is enabled by default. If you do not require consent management, you must actively disable it, or tracking calls are not sent.
• Low Impact Changes
  • Fixed a crash relating to older 32 bit devices due to a large integer timestamp (changed from Int to Int64).
  • Added Dispatch Queue module to allow data collected offline to be persisted when the app is terminated.

1.5.0 (April 2018)

• First release of Tealium Crash Reporter.
• Minor bug fixes.

1.1.3 - 1.4.0 (2017)

1.4.0 (December 2017)

• High impact changes: these are changes to previous behavior or variable names/values. Before upgrading the library, be sure to check your account setup to ensure you are not relying on the previous behavior to trigger tags/actions. Also see List of Variables for a JavaScript extension to maintain backward compatibility between releases.

  • Removed deprecated track method with TealiumTrackType. Now calls trackView or trackEvent methods instead to differentiate between track call types.
  • tealium_event_type has been removed from all outgoing track calls, as it is now derived in Customer Data Hub Event Specs and does not need to be sent
  • Lifecycle module changed to use same NSNotifications as Objective-C library (UIApplicationDidBecomeActive and UIApplicationWillResignActive). This ensures lifecycle events are captured as quickly as possible.
  • device_orientation has been changed to simply Portrait or Landscape (same as Objective-C library), and a new variable device_orientation_full has been introduced to capture the z-axis orientation such as face up or face down.
  • device_build variable changed to device_os_build to be more descriptive. device_build is no longer sent. Mappings need to be updated if you were previously using this variable.
  • Attribution module: device_advertising_id has been changed from Identifier for Vendor (IDFV) to Identifier for Advertisers (IDFA). A new variable device_advertising_vendor_id has been added, which contains the IDFV.

• Low impact changes/general updates and improvements

  • New schemes added to Framework project to allow device-based testing.
  • Modified sample Tealium helper file to allow usage with Objective-C apps, and align with best practice.
  • Fixed RemoteCommands example in sample TealiumHelper file.
  • Attribution module: Added support for Apple Search Ads API. If this module is used, Tealium collects attribution information from the Apple Search Ads API.
  • Collect module: Added config method to override collect URL.
  • Connectivity module: Improved logging when device connection changes. Added helpers to get the current connection type.
  • Core: Added call_type variable to view calls.
  • Added screen_title to view calls, which is set to the "title" parameter passed into the trackView call. For track calls, tealium_event is set to the string value that is passed in as the first parameter.
  • FileStorage module: Fixed bug that caused data not to be persisted to disk due to permissions error.
  • Lifecycle Persistent Data: Changed implementation of NSKeyedUnarchiver to support Swift 4.0, and add additional error checking.
  • Logger module: Improved logging for Persistent Data.
  • RemoteCommands module: Removed deprecated enable/disable methods.
  • TagManagement: Minor updates for Swift 4.0 compatibility.

    • Added Network (carrier) info (MNC, MCC, ISO code).
    • Added current connection type.
    • Added charging state information.
    • Fixed bug that caused battery to show as -100.
    • Added granular device model. For example, iPhone 7 (GSM).
    • “device_build” variable changed to "device_os_build" to be more descriptive. "device_build" is no longer sent. Mappings need to be updated if you were previously using this variable.
    • "device_orientation" has been changed to simply Portrait or Landscape (same as Objective-C library), and a new variable "device_orientation_extended" has been introduced to capture the z-axis orientation such as face up, or face down.
    • Support added for WatchKit device data (limited data available).
