Apple Requiring Developers to Support The iPhone XS Max and 12.9-Inch iPad Pro Starting March 27

Apple has updated the App Store submission requirements for developers today, requiring support for their latest devices. In the update, Apple has informed developers that starting March 27, 2019, all apps must support the display sizes of the iPhone XS and the 12.9-inch iPad Pro natively. Effectively this means that developer will have to use the iOS 12.1 SDK for their apps.

Starting March 27, 2019, all new apps and app updates for iPhone or iPad, including universal apps, must be built with the iOS 12.1 SDK or later and support iPhone XS Max or the 12.9-inch iPad Pro (3rd generation)


By requiring developers to use the latest SDK, it assures that apps have a native look-and-feel on the company’s largest screened devices. To drive the point further, developers will also have to submit screenshots when they submit an app for review. The change in policy not only impacts new apps submitted to the App Store but Apple is also requiring any updates after March 27, 2019 to be using the iOS 12.1 SDK and screenshots for the larger devices.

Apple’s justification for this change is simple: More than 80% of all devices are now running iOS 12 on them. The Cupertino tech giant wants to assure that developers are building for those devices.

If you have an iPhone XS Max of 12.9-inch iPad Pro, this is obviously good news for you. While most developers have been building on the iOS 12.1 SDK and natively supporting those devices, there are always stragglers. This will force those laggards to catch up or they simply cannot update their app.
