Apple reminds us that iOS 11 is now in the hands of hundreds of millions of people around the world, and starting July 2018, all new iOS apps and updates submitted to the App Store must be built with the iOS 11 SDK, plus support iPhone X. Also, all new iOS apps and updates for iPhone, including universal apps, must support the Super Retina display of iPhone X.
iOS 11 SDK requires Xcode 9, and Xcode 9 requires macOS High Sierra. If you have been limping along on macOS Sierra, you will have to update OS, Xcode, and iOS SDK.
Here are other things to keep in mind that come along with the iOS 11 / Xcode 9 update mandate.
- If your app integrates Core ML, or ARKit, make sure to use best practices and test before submitting (our guess is they are going to crack down on developers not “getting things just right” for their users.
- Remember to update your information property list (info.plist) with new device requirements when submitting an app update that takes advantage of the latest technologies.
- You now will have to include iPhone X screenshots with a resolution of 1125 by 2436 pixels for portrait orientation and 2436 by 1125 pixels for landscape orientation in your app meta data.
- Your App Store icon should now be included as part of your project bundle, not in iTunes Connect.
