Starting April 2020, all new apps and app updates will need to be built with the iOS 13 SDK and support the all-screen design of iPhone XS Max or later.
And LaunchImages is deprecated.
I think the alternative is to use LaunchScreen.storyboard.
However, for example, because Unity generates .nib (xib), it may be more convenient to use nib (xib) files instead of Storyboard.
Storyboard is also nib when installed on the terminal.
Therefore, I think that it is OK to set LaunchScreen with nib (xib). Does anyone have any information?
