Weird ScrollView bug when backgrounding during .sheet presentation
struct ContentView: View {
@State var presentSheet1:Bool = false
@State var presentSheet2:Bool = false
var body: some View {
ScrollView {
VStack {
Button {
presentSheet1 = true
} label: {
Text("1")
.font(Font.system(size: 32))
.frame(minWidth:0, maxWidth:.infinity)
.background(Color.red)
}
Button {
presentSheet2 = true
} label: {
Text("2")
.font(Font.system(size: 32))
.frame(minWidth:0, maxWidth:.infinity)
.background(Color.green)
}
Spacer()
}.sheet(isPresented: $presentSheet1) {
Color.red
.overlay(Text("1").font(Font.system(size: 128)))
}.sheet(isPresented: $presentSheet2) {
Color.green
.overlay(Text("2").font(Font.system(size: 128)))
}
}
}
}

To reproduce this bug make a basic SwiftUI iOS project and replace the default ContentView with this view, then:

  1. Launch the app
  2. Tap on either of the buttons
  3. Background the app (by tapping on the Home button, or swiping up)
  4. Return to the app and dismiss the sheet by swiping down on the sheet
  5. Try to tap on the "1" button,

Instead of the "1" button being tappable instead the top several points of the screen are completely unresponsive, around the top of the "2" button there is a tappable region, but it points to the "1" button instead.
