You would have to recompile the Android version for iOS, and also root your iPhone as otherwise you can't install stuff outside the store, so not easy.
Hey. I came across this post during my quest to bring OpenXcom to iOS. I've compiled OpenXcom for iOS and found a third party app store to host it meaning no jailbreak required. I've put the details in the following post. https://openxcom.org/forum/index.php/topic,6955.0.html
Woah! Finally! I shoud repair my iPhone to try it. I'll spread the notice.
Hello, everybody!After a catastrophic error that resulted in a bootloop on my Android (which I could not recover even with Recovery mode), my father gave me his old iPhone 5 with iOS 10. I know that APKs can not be installed on iOS, but does anyone know any way to play OXC and install mods on this platform? My phone will return from Technical Support in a month or more.
OXCE now also supports iOS: https://openxcom.org/forum/index.php/topic,7047.0.html
