iOS10 ，xcode8 运行真机奔溃

奔溃信息如下：

dyld: could not load inserted library '/Developer/usr/lib/libBacktraceRecording.dylib' because image

/Developer/usr/lib/libBacktraceRecording.dylib: code signature invalid for '/Developer/usr/lib/libBa

解决办法有3个：

1）Clean 后重新 Build

2）退出Xcode后删掉目录 ~/Library/Developer/Xcode/DerivedData

3）重启 iPhone
