iOS: limit app to 64-bit devices only

According to the latest Apple WWDC, starting from ios 9 there should be a way to limit installing app only on 64 bit devices.

I searched in XCode for this option but could not find anything. Is this already possible and if yes, how can i enable it?

Solution

  • 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.
