BETA iOS9 deployment to test devices

Question

Can I download iOS9 + Xcode 7 and still deploy test apps to devices that use the current version of iOS?

Sorry for the relatively stupid question, I'm a new developer and not sure how it has worked in the past and I can't find anything on the developer site....

Thanks a lot.

Answer 1

With any iOS version, it depends on the minimum requirements for the app you're making. If you use any code that requires iOS 9 or set your projects requirements to iOS 9, it won't run on iOS 8 devices. But if you make an app designed for iOS 8 or earlier, it will run on those devices, even if you make it using Xcode 7.

But since you're a new developer, keep in mind: anything made with Xcode 7 can't be submitted to the App Store until Xcode 7 is officially released, likely this fall. That applies to everything, regardless of target OS.

So if you want to release your app this summer, make your app with the current version of Xcode, and just use the new Xcode 7 beta to experiment, and to develop future releases.

Sumple rule set your deployment target to lower & it will be supported in all higher version os.

But before launching on store better you review them in those environment because with higher version certain API have changed few of them might depreciated & replaced with others.

As per current situation make base 7.0 as deployment target & your app will work on majority of devices/users.
