Maximum build file sizes
For iOS, tvOS, and visionOS apps, verify that your app doesn’t exceed the maximum file sizes on the supported operating systems. Your app’s total uncompressed size must be less than 4GB. You can host larger assets using on-demand resources or Background Assets. Apple Watch apps must be less than 75MB. In addition, each Mach-O executable file — for example, app_name.app/app_name
— must not exceed these maximum file sizes.
