iOS原型调试，Swift编译器错误

ios swift

iOS原型调试，Swift编译器错误,ios,swift,prototype,Ios,Swift,Prototype,当我进行原型调试时，Xcode6.2说 could not build Objective-C module 'UIKit' /Applications/Xcode-Beta.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.2.sdk/System/Library/Frameworks/UIKit.framework/Headers/UICollectionViewLayout.h:11:9

当我进行原型调试时，Xcode6.2说

could not build Objective-C module 'UIKit'

/Applications/Xcode-Beta.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.2.sdk/System/Library/Frameworks/UIKit.framework/Headers/UICollectionViewLayout.h:11:9: 'QuartzCore/CATransform3D.h' file not found

但当我在iOS模拟器上运行代码时，一切都正常错误仅在原型调试时发生

我的构建设置有什么问题吗？

什么是“原型调试”？在iPhone上运行应用程序删除Xcode并重新安装。
