I have just upgraded to Xcode 4. When I am making any king of changes in an xib file this doesn’t show on my simulator. I have even removed to xib from the project or quit Xcode – but still nothing – it runs as before.
It seems like the files are not compiled anymore.
Have you faced this kind of problem?
If you’re not sure if its compiling a file, just do a clean (default is command+K i think) and build again
