Hello,
A few GRDB users of the GRDB library (http://github.com/groue/GRDB.swift) see warnings with Xcode 15 beta, similar to this one:
objc[59263]: Class _TtC4GRDB25ValueObservationScheduler is implemented in both /Library/Developer/CoreSimulator/Volumes/iOS_21A5248u/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 17.0.simruntime/Contents/Resources/RuntimeRoot/System/Library/PrivateFrameworks/GRDB.framework/GRDB (0x1c0be5490) and /Users/***/Library/Developer/CoreSimulator/Devices/77039DFC-6093-4B01-A3F6-4113835E7E0F/data/Containers/Bundle/Application/4BA438C9-3327-44DD-ADC8-B54B45B98742/***.app/*** (0x104325598). One of the two will be used. Which one is undefined.
A few of those reports:

I believe some of those users have reported the problem with Feedback Assistant.
I have two questions:
- Is there a way to workaround this problem until a release of Xcode that fixes it?
- Is there an actual risk of having the runtime use mismatching GRDB classes?
