我通过清除xcode中的首选项中的派生数据来解决这个问题

None of the provided answers worked for me. In my case, I finally fixed the error by updating the target architectures in Build Settings/Architectures/Valid Architectures to $(ARCHS_STANDARD), as arm64 was missing. This was not prohibiting the project to build, although a warning was issued recommending updating the valid architectures, but the "app could not be opened" error was shown at run time. I surmise this error is rather generic and not always linked with a permission issue, but may be displayed when the generated app package is invalid.

我的解决方案是:

在你的终端输入: 打开~ /图书馆/开发/ CoreSimulator /设备/ 删除适当的文件夹 再次编译，它应该工作

为我解决这个问题的方法是将“仅构建活动架构”从“否”设置为“是”。

我的用例有点独特。我使用app_spec的info_plist属性来额外指定信息。plist属性通过哈希。

但是，设置CFBundleExecutable键会导致权限错误。我把它拿掉了。

我正在使用Xcode 6 GM，我遇到了同样的问题。 我所做的是去构建设置->构建选项(你可以搜索“编译器”)， 然后将“Compiler for C/ c++ /Objective-C”的选项改为默认编译器。
