No .app bundle found in the pack

简而言之，就是打包的时候，应该使用发布证书，但是使用了开发证书，所以才会出现这个问题，修改为发布证书即可

When you see "iPhone Developer" in the code signing identity, that means Xcode will automatically select a matching identity to sign the app (It doesn't mean that no profile is selected).

From what I can see it looks like "iPhone Developer" is chosen for both Debug and Release configurations which will likely cause a problem because you cannot submit a Developer signed app to the App Store, it must be signed with a Distribution certificate and Distribution profile.

You will need to ensure that you have created a Distribution Certificate and profile to sign your app with before archiving it and submitting it via Xcode.

I would recommend you read up on how app store distribution works from the Apple documentation here:

Then if you still are having trouble, read the trouble shooting guide from the docs here:
