Is there a way to set my app in the App Store for download only from 64bit devices iPhone 5 and up ?
If I am not mistaken this is not allowed for the AppStore.
The only way I can think of that would be accepted is if your App uses Metal.
Possibly the device capabilities plist entry would do it
See UIRequiredDeviceCapabilities armv7 entry
Right but unless this has changed, the app won’t pass App Store review. Other than setting a minimum iOS version, you aren’t supposed to deliberately prevent the app running on devices like that.
Could you detect which device they are on and then not play the music? Seems weird to me, but you could make it an option to play the music on 32 bit with a warning or poor performance, and have the music playing on 64bit with the option to disable it.
or = of. Can’t edit
