iOS Device Compatibility

Unreal Engine 4 (UE4) currently supports iOS 10.1 and above. The following charts give information about device-specific compatibility for Engine features. 

We have not yet tested all iOS devices but this table will give you an idea what features we expect to work well on each device. We plan to expand and refine this section as new devices are released and we broaden the devices we are testing in house.

Mobile Content Scale Factor is a way to scale the resolution of your project to best fit the screen resolution of the mobile device being used to view your project. You can create and store multiple device profiles by creating a new configuration (.ini) file called DefaultDeviceProfiles.ini in your project's config folder.
