Question

Did you ever try to handle the event when you press intro and the keyboard dismiss in SwiftUI using TextField?

TextField("type your name here", text: $yourName)

How can I know when user dismiss keyboard pressing 'intro' button?

Answer 1

You can use onCommit parameter from TextField. Here is an example:

TextField("type your name here", text: $yourName, onCommit: {
    print("return key pressed")
})

---

From the documentation:

/// [...]
///   - onCommit: An action to perform when the user performs an action
///     (for example, when the user presses the Return key) while the text
///     field has focus.
public init(_ titleKey: LocalizedStringKey, text: Binding<String>, onEditingChanged: @escaping (Bool) -> Void = { _ in }, onCommit: @escaping () -> Void = {})

Answer 2

After the TextField is declared, add a closure and fill it with this code: UIApplication.shared.keyWindow?.endEditing(true)

So altogether it looks like

TextField($yourText){
    UIApplication.shared.keyWindow?.endEditing(true)
}
