Release notes

Here is the release notes, known issues, and hot fix information for iOS SDKs 4.x for Experience Cloud Solutions:

April 13, 2021: Version 4.21.2

Visitor ID Service - Fixed an issue where empty advertising identifiers were synced to the Visitor ID Service.

General - Fixed an issue that could cause SQLite exceptions during app shut down.

General - The SDK is now distributed using XCFrameworks in order to support hardware with the new Apple M1 architecture while maintaining support for existing Intel architecture.
- IMPORTANT: Upgrading to AdobeMobile XCFrameworks requires Xcode 12.0 or newer
- IMPORTANT: If using Cocoapods, upgrading to AdobeMobile XCFrameworks requires Cocoapods 1.10.0 or newer

Visitor ID Service - Added device_consent status parameter when setAdvertisingIdentifier is called after ad tracking is enabled/disabled.
Analytics - Fixed a bug that was delaying Analytics hits from being sent on an install when iAd.framework is linked and the device has "Limited Ad Tracking" enabled.

General – Fixed a bug that prevented deeplink URLs with multiple equals sign in query param from being properly handled.

General - Resolved a potential crash caused when Swift enums are included in context data for tracking calls.
Target – Target Session Id will now be added as a context data parameter ‘a.target.sessionId’ in the internal Analytics for Target hit sent to Adobe Analytics.

Lifecycle - Added a new API, pauseCollectingLifecycleData, to mitigate the abnormal session length data that was reported from some old iOS devices.

In App Messaging - Fixed a bug where cached or bundled images could not be loaded in the full screen messages.

In App Messaging:
- On devices running iOS 10 or newer, the UserNotifications framework is now used to schedule local notifications for apps that are linked to the UserNotifications.framework.
- Fullscreen messages now use WKWebViews from WebKit.framework, which must be linked in your Xcode project.
- Fixed a bug where the Push click-through payload could not be used as traits for In-App Messaging.
- Fixed a crash issue.
General - Fixed a bug where SDK data was synchronized to the paired watchOS app on every Analytics call.

Reverted a change that was introduced in version 4.18.6 which, in some environments, caused a crash on devices that were running an iOS version older than 11.0.
Adobe Target: Added the requestLocationParameters property in ADBTargetRequestObject, which enables the impressionId to be sent with Target requests.

Adobe Target: All requests now include the client and the sessionId in the URL query parameters.
Adobe Target: Fixed a memory leak.
Visitor ID Service: The visitorAppendToURL and visitorGetUrlVariablesAsync APIs no longer double-encode their return values.

The double-encoding was causing the return values from those APIs to be flagged by certain security reviews.

Analytics - Append push opt-in status to Lifecycle data when push notifications are enabled.

Visitor ID Service - Increased the return timeout for the visitorGetUrlVariablesAsync API to 30 seconds.
Visitor ID Service - The setPushIdentifier API call now sends a sync call to the Visitor ID Service every time it is called.
