How can I change the orientation of the build in Unity SplashScreen in iOS(Free), my game is in Landscape orientation but the SplashScreen is always in Portrait orientation and I would like to have both the same orientation.
Do not manipulate the Unity SplashScreen by hand, your app stops working immediately!!
Create a new Xcode project, with a diffrent name than the orginal one, pass your Unitybuild to it and the problem is gone!
At least this was the working solution for me.(Note that I have checked the orientation of the images in Unity and Xcode more than once, they were all correct)
