Prepare to Make Unreal Games with Unreal Engine – Installing and Setting Up - Learning Unreal Engine iOS Game Development - page 2

Getting ready and setting up
Despite the relative openness of UE4, I would recommend you use a Mac OS X computer
for developing iOS games using Unreal (or any other engine for that matter). It's important
as it gives you direct access to XCode, which you will need to use to do the following:
• Debugging your game using its console
• Analyzing the game's performance using its tools (instruments)
• Adding a third party's libraries to the XCode project
• Adding platform-specific code to the game's XCode project
