I can estimate it as follows. Cocoa/UIKit works in ObjC. ObjC is a super set of C that translates the objc parts to calls to objc_msgsend. Go supports ARM/OSX. Go makes it pretty easy to call into C Therefore it should be pretty easy to port to iOS, all you need to do is to write a bit of go to interface with objc_msgsend.
