iOS: limit app to 64-bit devices only


In Xcode, set the following values:

Build settings > Architectures

  • Set to arm64 only. (click Other -> + and than enter arm64)

Build settings > Valid architectures

  • Set to arm64 only.

Info.plist

  • Set UIRequiredDeviceCapabilities to arm64 only.

The app will then not be able to run on a device that does not support 64-bit code.
