Build your apps using Xcode 11 GM seed, test them on iOS devices running the latest GM seeds, and submit them for review.

Apple also confirmed that all new apps a must support the iPhone XS Max screen size and later once April rolls around.

Users of existing iPhones can download iOS 13 on September 19th, a day ahead of the release of iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max. Not long to wait now!
