I made my game and exported it using cordova, then I made build in Intel XDK for iOs. I added my game on iTunes connect and they send me a letter in which says :
"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."
How can I do 64 bit support?
