Aprove answer

Try to switch your Mac OS language settings to English (System Preferences -> Language & Region), add English in Preferred Languages and set it to Primary. It helped me, I had Czech as my Primary Language and Xcode crashed every time I tried to access Options in Edit Scheme window. Works in Xcode 8, hadn't tried it in previous versions.


use command: defaults delete com.apple.dt.Xcode

Solved my issue :)
