I have solved the problem by installing a clean copy of Catalina.

Answer 4

For me it was not enough to update Xcode, I also had to update my Mac OS to Catalina. Everything else did not work.

Answer 5

Some of your images are not copied properly Go to Project -> target -> Build Phases -> Copy Bundle Resources and check which file is missing copy the file here and that will work.

Answer 6

You might have migrated from a normal project to use an image.catalog. So you can definitely try to copy the bundle resource like launch images. It is so because migrating to an asset catalog for icons and launch images apparently doesn't always add itself to the target automatically.

You can find more on this here & here.

I hope that helps.
