From April 2021, all apps submitted for publication on the App Store will have to be built with Xcode 12 and the iOS 14 SDK.
It is a common practice to ban old versions of packages. But this time, developers don’t have much time to transition to new standards.
At the same time, Apple is delaying the introduction of new rules regarding data privacy. It was originally planned that with the release of iOS 14, all apps will be required to ask the user if they are ready to share data with third-party services. Now, this rule will only come into effect starting January 2021.
