After further investigation, the origin of my crash is from FirebaseMessaging.

I'm having what seems to be the same or similar issue, but CoreServices.framework doesn't appear in Build Phases, any idea? iOS 26 working great, but when I compile on iOS 18.5, I get this crash upon startup: Referenced from: <6D911850-31F9-34F9-A0B0-8C1A3A80FE67> /private/var/containers/Bundle/Application/3DD5AE67-E8FE-4032-B58F-BAC51485C2BA/{project}.app/{project}.debug.dylib Expected in: <050203DD-7488-307D-A999-E587314B041A> /System/Library/Frameworks/CoreServices.framework/CoreServices dyld config: DYLD_LIBRARY_PATH=/usr/lib/system/introspection DYLD_INSERT_LIBRARIES=/usr/lib/libLogRedirect.dylib:/usr/lib/libBacktraceRecording.dylib:/usr/lib/libMainThreadChecker.dylib:/usr/lib/libRPAC.dylib:/usr/lib/libViewDebuggerSupport.dylib Symbol not found: _NSUserActivityTypeBrowsingWeb Referenced from: <6D911850-31F9-34F9-A0B0-8C1A3A80FE67> /private/var/containers/Bundle/Application/3DD5AE67-E8FE-4032-B58F-BAC51485C2BA/{project}.app/{project}.debug.dylib Expected in: <050203DD-7488-307D-A999-E587314B041A> /System/Library/Frameworks/CoreServices.framework/CoreServices dyld config: DYLD_LIBRARY_PATH=/usr/lib/system/introspection DYLD_INSERT_LIBRARIES=/usr/lib/libLogRedirect.dylib:/usr/lib/libBacktraceRecording.dylib:/usr/lib/libMainThreadChecker.dylib:/usr/lib/libRPAC.dylib:/usr/lib/libViewDebuggerSupport.dylib
