How do I fix the “This app could not be downloaded because it’s integrity could not be verified”

The error message “This app could not be downloaded because its integrity could not be verified” typically occurs when you try to download and install apps from sources outside of the official App Store. iOS has strict security measures to protect users from potentially harmful apps, and this message usually indicates that the app you’re trying to install isn’t properly signed or verified by Apple.
