Usage

Just use it as you would use any other SwiftUI view!

struct ContentView: View {

    enum Responder {
        case first
        case second
    }

    @State private var text = "A test text"
    @ResponderState var focus: Responder?
    @State private var date = Date()

    var body: some View {
        ScrollView {
            VStack {
                SUITextField(text: $text, placeholder: "Insert a text...")
                    .inputAccessoryView {
                        ResponderNavigatorView(responder: $focus) // add default ResponderNavigatorView as input accessory view
                    }
                    .onReturnKeyPressed {
                        focus = nil // set focus to nil to close keyboard on return key tap
                    }
                    .leftView { // add a left view to clear text on tap
                        Button(action: { text = "" }) {
                            Image(systemName: "trash")
                        }
                        .padding(.horizontal, 2)
                    }
                    .responder($focus, equals: .first)
                    .uiTextFieldTextLeftViewMode(.whileEditing)
                SUITextField(text: .constant(date.description))
                    .inputAccessoryView {
                        MyAccessoryView() // add a custom accessory view 
                    }
                    .inputView {
                        // Use a date picker as input view!
                        DatePicker("Select date", selection: $date)
                            .frame(maxWidth: .infinity, maxHeight: .infinity)
                            .datePickerStyle(.wheel)
                            .labelsHidden()
                    }
                    .responder($focus, equals: .second)
            }
            .padding()
        }
        // apply style to all children text field!
        .uiTextFieldBorderStyle(.roundedRect)
    }

Known Issues

• When an external keyboard is connected and the software keyboard is hidden, on iOS 13/15 there are small layout jumps when switching from a text fields
• On iOS 14 this behavior is worse: the system tries to re-layout the component infinitely! Need to understand what actually happens under the hood…
