Xcode doesnt seem to update its interface and behaviour in response to my code. For instance, the connection inspector says that an object has an outlet connected to another, even though I removed the outlet long ago (and even the connected object). After renaming, it keeps old object names around. This wouldnt be a problem if it didnt prevent my app from buidling because of « unknown type RandomClass» (even though it recognize RandomClass since it autocompletes the name!). Restarting doesnt help. Any suggestion to make this progam behave itself? This is my first project and I may have missed some important settings.
