Cannot find TestView in scope

Question

I am seeing the following error in iOS14, I am not sure if it is a bug or a user error :-) I appreciate it is still in beta, so I will post this in the developer forums as well.

I am seeing the following error come up when I make a macOS app in SwiftUI - when I create the same as an iOS app, the error does not appear.

Do I need to do something special for macOS apps when it comes to importing SwiftUI modules?

Check the file target membership that has `TestView` defined — staticVoidMan, Aug 03 '20 at 04:42
Try to move TestView in same .swift file where that TabView is used. — Asperi, Aug 03 '20 at 04:45
This bug happens to me when I move files around. Close your Xcode project and reopen it again for the error to disappear. — Roland Lariotte, Aug 03 '20 at 05:02
Thanks for the feedback Asperi and staticVoidMan - your comments where both useful and I learned something. — jwknz, Aug 03 '20 at 06:58

Had this issue today because I renamed the file that contained the class. The solution was to delete the file and recreate it.

Don't forget to add it to your Target Membership

Clean the project
Close and relaunch the Xcode

This will solve the problem.

It didn't - I needed to add it to the target membership, which was said in the comments – jwknz Dec 26 '20 at 03:28

In my case the reason was that the protocol I was inheriting in the class, needed to be made public.

When you rename a swift View from Project navigator or refactor the name within a struct, check that the struct and preview name were updated accordingly.

You need to make sure that you've selected "Create folder references" when adding a new file to the project.
