错误消息是通用的，实际上并没有告诉您它的真正含义。

对我来说，我必须恢复早期的github回归，这给:

armv7 armv7s arm64

对建筑。

我也遇到过类似的问题。不知何故，我的值键可执行文件混淆了。只需将其更改回${EXECUTABLE_NAME}(在您的项目> Info下)。为我工作!

信息系统出了点问题。项目的Plist。我在Xcode 6 beta 4中创建了一个同名的新项目，然后替换了真实项目的信息。请用新的。然后，该项目建立并运行良好。

看看差异，看起来plist可能不知怎么搞混了游乐场的plist。捆绑包标识符是“com.apple.dt.playground”。iOS-18300-13”，可执行文件和捆绑包的名称是“iOS”以及其他一些奇怪的名称。

这是完整的差异，以防有人需要参考:

当路径不正确或试图获取文件夹的内容而不是路径时，也会出现此错误。

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.

我会进入Xcode文档所在的文件夹，点击command + I来获取信息。在底部，点击锁以解锁文件夹以编辑权限。如果权限看起来不错，勾选“应用到附带文件夹”的复选框，让它来做它的事情。我个人没有见过这个，也不确定这是否是你在编辑构建权限时在你的帖子中所说的。
