SOLVED: TextField - Dismiss keyboard - Clear button

Forums > SwiftUI

hi everybody!

does anyone know an easy and elegant way of dismissing the keyboard when finished with entry (especially when using numberPad or decimalPad) from a textField in SwiftUI? Also to add an clearButton and once the entry is cleared, that the placeholder will be shown?

Thanks a lot in advance for helping me out! Rgds, Martin


Hi Martin Hope this helps. Not sure the best way but found it works for me

struct ContentView: View {
    @State private var someNumber = ""
    @State private var enteredNumber = ""

    var body: some View {
        VStack {

            TextField("PlaceHolder", text: $someNumber)
            Button("Submit") {
                self.enteredNumber = self.someNumber
                self.someNumber = "" // Clear text
                UIApplication.shared.endEditing() // Call to dismiss keyboard

// extension for keyboard to dismiss
extension UIApplication {
    func endEditing() {
        sendAction(#selector(UIResponder.resignFirstResponder), to: nil, from: nil, for: nil)

if you want the view to move up and down to make room for keyboard you will need to add a func with

NotificationCenter.default.addObserver(forName: UIResponder.keyboardWillShowNotification, object: nil, queue: .main) { key in
            let value = key.userInfo![UIResponder.keyboardFrameEndUserInfoKey] as! CGRect
            self.value = value.height

        NotificationCenter.default.addObserver(forName: UIResponder.keyboardWillHideNotification, object: nil, queue: .main) { key in
            self.value = 0

and add .onAppear(perform: ----) to the view


Thanks a lot Nigel!

I had to chance my idea of creating my UI, but your way makes it really easy to use now. thanks a lot!

Rgds, Martin
