iOS & iPadOS 14.3 Release Notes
Update your apps to use new features, and test your apps against API changes.
Overview
The iOS & iPadOS 14.3 SDK provides support to develop apps for iPhone, iPad, and iPod touch devices running iOS & iPadOS 14.3. The SDK comes bundled with Xcode 12.3, available from the Mac App Store. For information on the compatibility requirements for Xcode 12.3, see Xcode 12.3 Release Notes.
App Clips
New Features
You can now launch an App Clip by scanning App Clip Codes designed by Apple, by using Camera or from Control Center. (71991284)
SKAdNetwork
Known Issues
To receive a postback from devices running iOS 14 or later, generate signatures using signature version 2.0 or later. Version 1.0 signatures don’t result in a postback on iOS 14 and later, even if the advertised app is installed and launched. (71474331)
Weather
New Features

Air-quality data is now available for specific locations in China mainland, and is provided by QWeather. (69005588)

Web Clips
Deprecations
The TargetApplicationBundleIdentifier in WebClip is intended for enterprise customers to launch a custom URL in a third-party browser, rather than to provide theming options. Beginning in iOS & iPadOS 14.3, pointing TargetApplicationBundleIdentifier to an app made by Apple is no longer supported. A Web Clip already installed via a configuration profile will continue to work; however, the TargetApplicationBundleIdentifier property will be ignored in newly installed Web Clips unless the configuration profile is deployed via MDM. For devices not enrolled in MDM, create a single-step shortcut with the Open App action, then add the shortcut to the Home screen. (71422092)
