I saw it at the bottom of "Build Settings" in 'User-Defined', but it parameter is not changed, and my project still cannot run. I also saw a new option in 'Architectures', it's 'Excluded Architectures', up to now I donnot know what it does.

Thank u @zhangkk！If Apple technicians can fix this issue soon, please tell us, we all eager to know! @mgoemmel Hi, Markus, If I create a new OC project, and then i create a new widgetKit in it, the project will run nicely, widgetKit will run nicely too, thats very strange.

Tool: Xcode12-beta2 & Simulator The same problem I met!!!! How to get access to old projects？
