TextField("Name", text: $name)
I found this method
func focusable(_ isFocusable: Bool = true, onFocusChange: @escaping (Bool) -> Void = { _ in }) -> some View
but it's only available for MacOS, How could I do something similar for iOS ?

To check if the String value is empty I am going to use isEmpty that Swift provides. In the code example below I have two UITextFields which are called userNameTextField and userPasswordTextField. I first read the values that each UITextField contains and then check if these values are not empty.
You just make a View with all the code you want for the SecureTextField and the TextField then all you have to do is call the HybridTextField where ever you need it. Nice!
You can create a custom text field and add a value to make it become first responder. Note: didBecomeFirstResponder is needed to make sure the text field becomes first responder only once, not on every refresh by SwiftUI !
You can use the initializer init(_:text:onEditingChanged:onCommit:) present in textfield. There you will be getting an action triggered when you begin editing and end editing. You can find out the minimal example below.
import SwiftUI
struct ContentView: View {
@State private var greeting: String = "Hello world!"
var body: some View {
TextField("Welcome", text: $greeting, onEditingChanged: { (editingChanged) in
if editingChanged {
print("TextField focused")
} else {
print("TextField focus removed")
}
})
}
}
Hope this helps.
