Hello,
I found that the GRDB dependency unfortunately causes a crash when you run UI tests in Xcode 27 beta 4 (the most up-to-date version at the time of writing this).
The reason that's logged for the crash is
Class of category DEDSupport at 0x1ed106070 in /private/var/run/com.apple.security.cryptexd/mnt/com.apple.iPhoneOS.SimulatorRuntime-v24.1.5390.6.w4toDq/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 27.0.simruntime/Contents/Resources/RuntimeRoot/System/Library/PrivateFrameworks/DiagnosticExtensionsDaemon.framework/DiagnosticExtensionsDaemon is set to 0xbad4007, indicating it is missing from an installed root

I created a demo project over here https://github.com/JanGorman/UITestDemo that shows the issue. Just adding the dependency is enough to trigger the issue.
