I use react-native to develop an APP and use LaunchScreen.storyboard to show an launch screen . It works on iPhone 12 series (include iPhone 12 mini ) and iPhone 13 series and even if iPhone 8 series ,in those simulator I CAN see the launch screen ,but it was very confuse that when I run my APP on iPhone 11 series and iPhone X(Xcode13 do not have iPhone X simulator),the launch screen is white or blank ,I test it on the physical iPhone X but it still come to a blank screen . why some simulator are good and only 11 series have problem . Xcode version is 13 iOS version is 15 here is my LaunchScreen.storyboard: "images" : [ { "filename" : "iPhone12.png", "idiom" : "universal", "scale" : "1x" }, { "filename" : "iPhone12.png", "idiom" : "universal", "scale" : "2x" }, { "filename" : "iPhone12MAX.png", "idiom" : "universal", "scale" : "3x" }, { "filename" : "iPhone5.png", "idiom" : "iphone", "scale" : "1x", "subtype" : "retina4" }, { "filename" : "iPhone5.png", "idiom" : "iphone", "scale" : "2x", "subtype" : "retina4" }, { "filename" : "iPhone5.png", "idiom" : "iphone", "scale" : "3x", "subtype" : "retina4" }, { "filename" : "iPhone8P.png", "idiom" : "iphone", "scale" : "3x", "subtype" : "736h" }, { "filename" : "iPhone8.png", "idiom" : "iphone", "scale" : "2x", "subtype" : "667h" }, { "filename" : "iPhone11P.png", "idiom" : "iphone", "scale" : "3x", "subtype" : "2436h" }, { "filename" : "iPhoneXSMAX.png", "idiom" : "iphone", "scale" : "3x", "subtype" : "2688h" }, { "filename" : "iPhone11.png", "idiom" : "iphone", "scale" : "2x", "subtype" : "1792h" } ], "info" : { "author" : "xcode", "version" : 1 } } and all the picture have right size
