I have a watchOS app and it’s iOS counterpart in the AppStore. For now, my app support iOS 15 and watchOS 8.
The next version will make a huge step forward and supports iOS 17 and watchOS 10.
I have a question :
If someone has an iPhone on iOS17 and a watch on watchOS 8, will the AppStore update the app ?
It will be incompatible as the new iOS app won’t work with the old watchOS one.
I hope the AppStore won’t propose the update in this case to avoid impacting users with a modern iPhone and an old Apple Watch who can continue with the previous app version. What’s your advice ?
After checking on real devices: iPhone on iOS17 and Apple Watch run-in watchOS 9, I have verified that App Store don't install the new version if both minimum OS requirements are not met. So it's handled perfectly well.
