I installed XCode Version 10.2 beta 3 (10P99q) on my development Mac running 10.14.4 Beta (18E194d) and installed iOS 12.2 (16E5191d) on an iPad and when I build and run a Swift app on the iPad it crashes during loading with:
dyld: Symbol not found: _OBJC_CLASS_$__TtCs12_SwiftObject
Referenced from: /var/containers/Bundle/Application/16B3DA1B-3449-46A3-9DF8-DB70FFB87F66/OurApp.app/OurApp
Expected in: /usr/lib/swift/libswiftCore.dylib
in /var/containers/Bundle/Application/16B3DA1B-3449-46A3-9DF8-DB70FFB87F66/OurApp.app/OurApp
The Xcode Deployment Target is 12.1.
Do I have something misconfigured or is this set of Beta builds not working?
Using the same Xcode, building and running the app on an iPad with iOS 12.1.1 runs fine.
Thanks.
