Comment (by raimue):

 I cannot reproduce your problem with the patch. This is caused because
 post-patch failed, so the next time you want to build, MacPorts will try
 to apply the patch again. Please run `sudo port clean MacVim` before
 trying again.

 I cannot reproduce the issue with Xcode 9 on my macOS 10.12. Do you have a
 full installation of Xcode 9? Try reinstalling "Command Line Tools (macOS
 10.12) for Xcode 9" from the .dmg provided at
 [https://developer.apple.com/download/more/?q=Command%20Line%20Tools%20(macOS%2010.12)%20for%20Xcode%209
 developer.apple.com].

 As something like this has also happened in the past, do not delete
 anything from `/Applications/Xcode.app/Contents/Developer/Platforms/` and
 leave all of iPhoneOS/watchOS/etc. in place, even if you do not develop
 for such devices. The macOS platform appears to have cross-dependencies to
 these other platforms.
