Hello, today I tried to check out Apple's CoreNFC-Demo they showed at WWDC19. I did only following:- open FishTagCreator-Xcode-project- change Development Team to my Apple Developer Subscription Account- load the app on my iPhone 7After loading the App and clicking on "Write to Tag" (even without any tag close to the iPhone) I got following error:"Thread 5: signal SIGABRT"after running several times again without any luck I got all "Thread 2: ...", "Thread 3: ..." until "Thread 8: signal SIGABRT" errors.Does anybody know how to resolve this? Is the iPhone 7 the problem? Currently running iOS 13 beta 4.
