Xcode中5：「xcodebuild聯編」失敗，即使是在「空白應用程序」模板

Question

Issues between xcodebuild and Jenkins促使我嘗試xcodebuild在香草Empty Application模板它仍然失敗：

>> xcodebuild -target FizzBuzz -sdk iphonesimulator7.0 -arch i386 
The following build commands failed: 
ProcessPCH /var/folders/64/<someHash>/C/com.apple.DeveloperTools/5.0-5A1413/\ 
Xcode/SharedPrecompiledHeaders/FizzBuzz-Prefix-<someHash>/FizzBuzz-Prefix.pch.pch 
FizzBuzz/FizzBuzz-Prefix.pch

Xcode 5.0 
Build version 5A1413 

什麼是xcodebuild正確的咒語？

Answer 1

這3人的關鍵問題對我來說：

2. 使用-scheme選項與xcodebuild ...
3. ...和ONLY_ACTIVE_ARCH=NO。
