I upgraded to Xcode 7 yesterday and I'm getting a bunch of errors from Xcode. The program compiles / runs fine, but when programming it says things like No known class method for selector..., Use of undeclared identifier, No visible @interface for..., or Receiver type '...' for instance message is a forward declaration.
All of these errors, I assume, are coming up because it isn't using my precompiled header (*.pch) which includes the files needed for it to know about those classes.
How do I tell Xcode to look at the precompiled header?
I'm only using Objective-C.
