What happens if I do not support arm64 in my app?

问题

If I remove arm64 architecture from the build settings of Xcode and retain only armv7 and arm7s in my app what will happen?

1. What are the issues which may occur?
2. Will my app work on all iOS devices?

回答1:

Your app should continue to work. However as of June 1 2015, all of the app uploads to the Apple App Store must contain the arm64 slice.

As Apple wrote in a recent news post:

64-bit and iOS 8 Requirements for New Apps

October 20, 2014

Starting February 1, 2015, new iOS apps uploaded to the App Store must include 64-bit support and be built with the iOS 8 SDK, included in Xcode 6 or later. To enable 64-bit in your project, we recommend using the default Xcode build setting of “Standard architectures” to build a single binary with both 32-bit and 64-bit code.

You will not be able to submit your app to the store. Apple is pushing forward x64 architectures.
