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.

因为我今天早上也遇到了这个问题，没有一个答案对我有帮助，尤其是在我的情况下。经过几个小时的努力，我终于找到了问题所在。

实际上，在故事板中工作时，我错误地重命名了我的“Main”。故事板“到”。并将其更改为“Main”。故事板解决了我的问题。

解决方案(根据我的问题):可能是你重命名了任何文件，因为xcode无法加载它，并提出了一个问题。 例如:如上文所述更改“可执行文件”名称的情况 可能的问题区域:可能是您使用的最后几个文件。

在Xcode中执行以下操作

窗口->组织者->项目->应用程序的问题->删除按钮在派生数据。

然后我清理了项目，瞧

作品

我的项目也遇到了同样的问题。后来发现项目中使用的第三方(fmdb for SQLite)文件包含Info.plist。

简单地删除信息。Plist文件为我工作!
