TextFields using decimalKeyboard not scrolling to visible area when moved from a field using the nor-CodePudding

Any idea why Field 3 and Field 5 do not get visible when active if the previous field was using the normal keyboard?

In the following code, if you tap on Field 1 and immediately after you tap on Field 3 or Field 5, they will not be visible; they get hidden by the keyboard.

Please note that Field 3 and Field 5 use the decimalPad keyboard while the rest of the fields use the standard keyboard.

  struct TextFieldScrollingIssue: View {
    @State private var testInput:String = ""
    
    var body: some View {
        VStack{
            Form {
                TextField("Field 1", text:$testInput)
                Spacer()
                Spacer()
                Spacer()
                Spacer()
                Spacer()
                Spacer()
                Spacer()
                Section(header: Text("Section 1: ")) {
                    TextField("Field 2", text:$testInput)
                    TextField("Field 3", text:$testInput)
                        .keyboardType(.decimalPad)
                }
                
                Section(header: Text("Section 2: ")) {
                    TextField("Field 4", text:$testInput)
                    TextField("Field 5", text:$testInput)
                        .keyboardType(.decimalPad)
                }
            }
        }
    }
}

CodePudding user response：

I think the scrolling mechanism is confused because you used the same variable for all of the TextFields. Obviously, in production, you would never have this scenario. The fix is simple, use different variables:

struct TextFieldScrollingIssue: View {
    @FocusState var isFocused: String?
    @State private var testInput:String = ""
    @State private var decimalInput:String = ""
    
    var body: some View {
        VStack{
            ScrollViewReader { scroll in
                Form {
                    TextField("Field 1", text:$testInput)
                        .id("Field 1")
                        .focused($isFocused, equals: "Field 1")
                    Text(isFocused?.description ?? "nil")
                    Spacer()
                    Spacer()
                    Spacer()
                    Spacer()
                    Spacer()
                    Spacer()
                    Section(header: Text("Section 1: ")) {
                        TextField("Field 2", text:$testInput)
                            .id("Field 2")
                            .focused($isFocused, equals: "Field 2")
                        TextField("Field 3", text:$decimalInput)
                            .id("Field 3")
                            .focused($isFocused, equals: "Field 3")
                            .keyboardType(.decimalPad)
                    }
                    
                    Section(header: Text("Section 2: ")) {
                        TextField("Field 4", text:$testInput)
                            .id("Field 4")
                            .focused($isFocused, equals: "Field 4")
                        TextField("Field 5", text:$decimalInput)
                            .id("Field 5")
                            .focused($isFocused, equals: "Field 5")
                            .keyboardType(.decimalPad)
                    }
                }
                .onChange(of: isFocused) { _ in
                    if let isFocused = isFocused {
                        DispatchQueue.main.async {
                            withAnimation {
                                scroll.scrollTo(isFocused)
                            }
                        }
                    }
                }
            }
        }
    }
}

Edit:

Based on the comment, I was able to reproduce. Edited code to use a ScrollviewReader, @FocusState and view ids to correct.
