To successfully convert a folder or app bundle into a functional IPA, you must follow this exact folder hierarchy: convert zip to ipa work
A common mistake is renaming app-files.zip directly to app-files.ipa . While your operating system will change the label, the internal directory architecture remains unchanged.

Before attempting to convert any ZIP to IPA, ensure you have the right to do so:
