Editor crashes when 'Build And Run' is opening the built Xcode project with macOS Sierra



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

    Same issue here. Unity crashes every time I try to 'Build & Run'. I'm using MacOS Sierra and Unity 5.4.2f2. 'Build' still works.

    Tested with Unity 5.4.2f1. same issue
    Tested with the Beta 5.5 as well. Same issue.
    Tried to resinstall XCode 8. Same issue.

    Tried the different work arounds and doesn't work for me.

    Running out of solution.

    Same thing here - 5.3.6p6 crashes when it finishes Build & Run for macOS Sierra + XCode 8 - every single time.

    Happens for me with macOS Sierra 10.12, Unity 5.4.1p3. Whenever I do a build and run Unity crashes when Xcode is launching. Build still transfers to Xcode though.

    Same thing here! after almost having a game ready for submission to the App Store, I decided to upgrade to Sierra. Been hell the last couple days, I'm downloading El Capitan to see if I can finally finish this project with no more bumps. :P
