I have lost the ability to jump to definition in Xcode. Every time I use the jump to definition option I get a ? in the middle of the screen. I've tried it many times and still nothing. Is there a library that could of gotten corrupted or deleted? FYI it works on my iMac just not my MacBook all of the sudden.
Jump to Definition doesn't work anymore
Probably the index is corrupted.
Try a Clean Build Folder to force reindexing.
Which version Xcode on what version macOS?
All projects on the same mac or just one?
I've done that a few times and closed Xcode in between. I always clean and close twice to make sure, but for some reason no matter what I try the app works but not jump to definition. The only thing I can think of was maybe the library/folder got deleted by accident?
