VS Cocoa - Error when trying to open Main.Storyboard: "id cannot be empty"

Cannot find a solution or definition online anywhere about this which is ridiculous.

When attempting to open the Main.Storyboard from the solution explorer I get a popup error stating simply "id cannot be empty."

I have no idea where to find this "id" and how to solve this problem. From what I can tell, one other dude on the internet also has this problem and nobody posted a solution for him in the VS forums.

Thanks, Jake

Solution

  • Just had the same problem and this is how I fixed it:

    Go to Tools->SDK Manager

    In the window which opens select Projects->SDK Locations->Apple

    Ensure the Apple SDK Location is pointing to the correct Xcode.app location e.g. /Applications/Xcode.app
