[url_launcher_ios] URLLauncherUITests fail on iOS 26 #173100
Description
Steps to reproduce
- Install xcode 26 beta
- Clone the packages repo
- Run the setup command in the script/tool directory (cd script/tool && dart pub get)
- Prep the example directory of
url_launcher_ios(flutter build or flutter pub get in the example directory) - Open
ios/Runner.xcworkspacein Xcode 26 beta 4 - Run the UrlLauncherUITests on an iOS 18.4 device (emulator/physical)
- Clear the test logs
- Run the UrlLauncherUITests on an iOS 26 device (emulator/physical)
Expected results
The test passes on both iOS 18.4 and iOS 26
Actual results
The tests fail on iOS 26
With the tools for iOS 26 installed in Xcode (Simulator support etc), I tested with xcode 16.3 (both on iOS 18.4 and iOS 26) and the results were the same, i.e, the test passes on iOS 18.4 but not on iOS 26.
Code sample
The url_launcher_ios example app is required for this.
