4.5.1: Missing 64 bit support iOS

Our game is getting rejected from AppStore for not having 64 bit support. We’re using Unreal Engine 4.5.1 and can’t use an upper version now since we need to launch this game soon. This is the message we got from Apple:

Dear developer,

We have discovered one or more issues with your recent delivery for “Special Ops for iPad”. To process your delivery, the following issues must be corrected:

Missing 64-bit support - Beginning on February 1, 2015 new iOS apps submitted to the App Store must include 64-bit support and be built with the iOS 8 SDK. Beginning June 1, 2015 app updates will also need to follow the same requirements. 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.

Once these issues have been corrected, you can then redeliver the corrected binary.


The App Store team

I think you have to use at least 4.6 for 64-bit, but you could ask this guy to see how he got it working in 4.5: Support for new 64-bit apps requirements from Apple - Mobile - Unreal Engine Forums
