Xcode 11 Beta 5 - 加载插件失败

Question

Opening a SwiftUI "Hello World" unaltered project in Xcode 11 beta 5 running on Catalina beta 4 produces a "Loading a plug-in failed" dialog warning.

Has anyone else experienced this or know how to solve it? I deleted Xcode, redownloaded it, reinstalled it and I'm still getting the same error.

No idea how to fix other than deleting the offending module, but that can't be right.

Answer 1

I was able to get my SwiftUI project running on Catalina beta 4 with Xcode beta 5. I too got the warning mentioned by OP.

And as mentioned in comments, the only negative impact I've seen is being unable to use the preview canvas. Other than that, everything else in my project is running well. Just using the simulator more ;)

Answer 2

this will get rid of the error message but will not bring canvas back.

Please go to: /Applications/Xcode-beta.app/Contents/PlugIns/UVKit.framework and delete all the shortcut files in all folders of UVKit.framework (Be sure DONOT delete orginal files).
