In the attached code snippet:
struct ContentView: View {
@State private var vText: String = ""
var body: some View {
TextField("Enter text", text: Binding(
get: { vText },
set: { newValue in
print("Text will change to: \(newValue)")
vText = newValue
}
))
}
}
I have access to the newValue of the text-field whenever the text-field content changes, but how do I detect which key was pressed? I can manually get the diff between previous state and the new value to get the last pressed char but is there a simpler way? Also this approach won't let me detect any modifier keys (such as Alt, Ctrl etc) that the user may have pressed.
Is there a pure swift-ui approach to detect these key presses?

I would like to understand how to programmatically set the position of a cursor in a SwiftUI TextField.
In UIKit this can be done using the selectedTextRange property, but I couldn't find a similar way to achieve this with pure SwiftUI.
I want to figure out something like setCursorPosition (index:) - maybe by tracking the position in a @State or any other way.
I understand that I can do this using UIViewRepresentable but I am looking for a pure SwiftUI solution and wanted to know if there is any.
import SwiftUI
struct ContentView: View {
var body: some View {
VStack {
Button ("Button 1") {
print ("Button 1");
}
.keyboardShortcut("k", modifiers: .command)
Button ("Button 2") {
print ("Button 2");
}
.keyboardShortcut("k", modifiers: .command)
}
}
}
I the above snippet, I have assigned the same keyboard shortcut (cmd +k) to 2 different buttons. According to the docs, if multiple controls are associated with the same shortcut, the first one found is used.
How do I figure out if Button 1 would be found first during the traversal or Button 2 ?
Is it based on the order of declaration? Is it always the case that Button 1 would be found first since it was declared before Button 2 ?
