My app suddenly won't run on the simulator. It still runs on my iPhone, but if I try to run it in the simulator it just freezes. The UI comes up but it's completely unresponsive and I can't tap anything. If I pause the project and look at the call stack I see a message saying "Application violated contract by causing UIApplicationMain() to return. This incident will be reported.". And in the console the last message I get is "void * _Nullable NSMapGet(NSMapTable * _Nonnull, const void * _Nullable): map table argument is NULL". Not sure if those are related but that's all I could find.
