I'm having Apple Mach-O Linker Error from 1) "_OBJC_CLASS_$_PFLogInViewController", referenced from: 2) "_OBJC_CLASS_$_PFSignUpViewController", referenced from: 3) "_OBJC_CLASS_$_PFUser", referenced from: 4) "_OBJC_CLASS_$_Parse", referenced from: 5) linker command failed with exit code 1 (use -v to see invocation)

Can i know what is Apple Mach-O Linker Error and the way to solve this error ?

It looks like a problem with the Parse library - did you add it manually (instead of using cocoapods)? If yes, you've probably missed something — Antonio, Jun 17 '15 at 14:36
Did you open up the new workspace it made after the pod installed? The original project would probably do this. — Dare, Jun 17 '15 at 14:40
And have you added [ParseUI](https://cocoapods.org/pods/ParseUI) if you're using visual parse components? — Antonio, Jun 17 '15 at 14:45
@Antonio i cant find the parseUI, what's the name of the UI? Cuz i cant get anything when i type in ParseUI — Beginner, Jun 17 '15 at 14:49
From now on, as the command-line warning mentioned, you must always open the workspace (.xcworkspace) and not the project (.xcodeproj). Quit Xcode and make sure you open the right one or it won't compile. — Dare, Jun 17 '15 at 14:49
Usually the same folder that contains your project. I am pretty sure that's the default behavior. — Dare, Jun 17 '15 at 14:55
