+Additionally since some time Apple requires 64 bit version of application binary when you are uploading to iStore.
+The best way to provide these is to create a bundle in which there are both 32bit and 64 binaries, so every device will be able to run the game.
+It can be done in three steps, first compile 32 bit version, then compile 64 bit version and then use ``lipo`` to bundle them into one fat binary, all those steps can be performed with following commands:

+    $ scons p=iphone tools=no bits=64 target=release
+    $ lipo -create bin/godot.iphone.opt.32 arm64 bin/godot.iphone.opt.64 -output bin/godot.iphone.opt.universal
