Trying to compile Lingon on macOS Big Sur with Xcode 12.5 results in errors from Interface Builder like these:

You probably know that you just need to change the 1050s in those files to 1060s.

Probably a 5 minute job -- I did a few other ports already.

Careful with a reinplace though -- there are often other 1050s that you want to miss, so do them by hand (IMHO).
