今天早上在我的应用程序上工作了几个小时后,Xcode就停止了让我在iPhone上测试我的应用程序.但我仍然可以在模拟器中测试它.

现在,当我构建一个项目时(注意:任何项目,甚至刚刚创建的空白单视图项目),我得到以下错误;

Codesigning /Users/name/Library/Developer/Xcode/DerivedData/testProject-brzcahttttlkoqeczajhqslodkkn/Build/Products/Debug-iphoneos/testProject.app/Frameworks/libswiftCore.dylib /usr/bin/codesign '--force' '--sign' '64F8B22715267CC0910110D9C97A2567591C0235' '--verbose' '/Users/name/Library/Developer/Xcode/DerivedData/testProject-brzcahttttlkoqeczajhqslodkkn/Build/Products/Debug-iphoneos/testProject.app/Frameworks/libswiftCore.dylib'

我在macOS Sierra 10.12.12上运行Xcode 8.2,在带有iOS 10.1.1的iPhone 6s上进行测试.

注意:我在从我的机器上完全删除Xcode后重新安装了Xcode,并删除并重新创建了所有硬件的所有配置文件.
