When "Build And Run" is used to open an iOS build with Xcode, Unity Editor crashes when opening Xcode.

Steps to reproduce:
1) Open the latest attached project (clean_836165_repro.zip).
2) 'Build And Run' for iOS or tvOS.

When building has finished and the progress bar is at 'Build & Install Unity Player", the Editor crashes. The build itself doesn't become corrupted and can still be opened manually.

This issue doesn't reproduce on OS X 10.11.6.
