Unable to compile on newer Xcode

Hello there,

I'm not quite sure if I headed to the correct category, but I have tried Xcode 12 Beta and no beta version has been able to build my two projects I'm currently working on.

For one of them, it always get stuck at compiling by throwing "Abort Trap 6", while the other seems to suffer a regression of closure type inference as it always complains of not being able to type check in a reasonable time.

For what it counts, both compiles well on Xcode 11.6.

Any help appreciated,

Thanks in advance
