I will add to this answer::: From @Chris Miles.

Close Xcode and delete the folder .xcuserdatad from within .xcodeproj/xcuserdata/. Then restart Xcode, the schemes should re-appear.

Close Xcode, and everything, about ios development like simulators, then run again you pod install if you are using cocoa pods.

That's works for me.
