Hello, I’ve set the Player Settings to use highest possible resolution but when the app runs on the device, it plays in 4:3 resolution and not the HD 1024 x 768 resolution. Is there something I have to set in Xcode? Or another setting in Unity perhaps?
Are you building the game for iPad? Maybe check out the Player Settings, under iOS Other Settings check you have Target Device set to include iPad, and also set Target Resolution to Native.
4:3 is the same as 1024x768, also 1024x768 is not HD res.
2048 is HD on ipad 3 or newer, but it is still 4:3
(4:3 just refers to the aspect ratio of width/height)
Make sure you have target set to both iPhone and iPad
