I'm trying to find information about the schedule of submitting apps for review for iOS 13.
I do aware it's in beta phase (both Xcode, iOS, and MacOS).
From past iOS versions, I remember that they usually give you one/two weeks pre-official iOS release to submit the apps using GM version of Xcode (Xcode 11 in our case) but I wanted to check if there is already official doc supporting it.
Here is the schedule of the Apple iOS 13 release :
iOS 13 release date schedule
- June 3: iOS 13 beta 1 and first look at WWDC 2019
- July: iOS 13 public beta release date for adventurous testers
- Early September 2019: iOS 13 Golden Master (final dev beta)
- Mid-September 2019: iOS 13 likely to launch with new 2019 iPhones
So if you see above there will be Golden Master release will be in early September. That will be almost like a final release for the developers point of view. So you can use that release for testing iOS 13 compatibility & features working or not.
So by this way you can be able to launch & schedule your release before the final release of iOS 13.
Hope this will help.
