I have just started trying to learn Swift, but one error keeps cropping up time and again and I can not find out why - "Editor placeholder in source code". What could be causing this (I am unable to post a picture of the code as I am a new member).
Thanks
Just happened to me using xcode 7.3.1 on existing code "that was fine yesterday". I couldn't see anything wrong, so I re-typed (the offending line to see where it went wrong) on the line above and deleted the original and error went away. A git diff shows no change.
