SwiftUI: Handling Keyboard Dismissal in a Form with Custom Input Validation
I'm working on a SwiftUI form that collects user input and performs custom validation. The issue I'm experiencing is that when the keyboard is displayed and I try to dismiss it by tapping outside the text fields, the keyboard doesn't go away as expected. I've implemented the form with several `TextField` components that validate user input based on certain criteria. I want to dismiss the keyboard when the user taps outside of the text fields, but the form seems to intercept the tap gestures, preventing the keyboard from dismissing. I've tried adding a `.gesture` modifier to the parent view, but it doesn't seem to work as I expected. Here's a simplified version of my code: ```swift struct UserInputForm: View { @State private var username: String = "" @State private var email: String = "" @FocusState private var focusedField: Field? enum Field { case username, email } var body: some View { VStack { TextField("Enter username", text: $username) .focused($focusedField, equals: .username) .textFieldStyle(RoundedBorderTextFieldStyle()) .padding() TextField("Enter email", text: $email) .focused($focusedField, equals: .email) .textFieldStyle(RoundedBorderTextFieldStyle()) .padding() Button("Submit") { // Perform validation } } .onTapGesture { // This doesn't dismiss the keyboard focusedField = nil } } } ``` I was hoping that setting `focusedField` to `nil` would dismiss the keyboard, but it doesn’t seem to have that effect when tapping outside. After some research, I found various suggestions like using a `UITapGestureRecognizer`, but I'm not sure how to implement that in a SwiftUI context. Is there a better way to achieve keyboard dismissal without disrupting the form functionality? Any insights on best practices or workarounds would be greatly appreciated!
