推荐答案

正常情况下升级Xcode：

As usual when upgrading Xcode:

• 清理构建文件夹（产品 - >（Alt键） - >清理构建文件夹）


• 清洁项目（产品 - >清洁）


• 删除派生数据
  
  
  
  • Xcode< 6.3：窗口 - >管理器 - >删除派生数据
  
  
  • Xcode> = 6.3：窗口 - >项目（选择项目） - >删除派生数据
  
  
  • Clean your build folder (Product -> (Alt key) -> Clean Build Folder)
  • Clean project (Product -> Clean)
  • Delete derived data
    • Xcode < 6.3: Window -> Organizer -> Delete derived data
    • Xcode >= 6.3: Window -> Projects (select project) -> Delete derived data

    然后尝试再次构建项目。

    Then try to build your project again.
