How to set TextField max length?

Is it possible to set a maximum length for TextField? I was thinking of handling it using onEditingChanged event but it is only called when the user begins/finishes editing and not called while user is typing. I've also read the docs but haven't found anything yet. Is there any workaround?

TextField($text, placeholder: Text("Username"), onEditingChanged: { _ in
    print(self.$text)
}) {
    print("Finished editing")
}

You can do it with Combine in a simple way.

Like so:

import SwiftUI
import Combine

struct ContentView: View {

    @State var username = ""

    let textLimit = 10 //Your limit
    
    var body: some View {
        //Your TextField
        TextField("Username", text: $username)
        .onReceive(Just(username)) { _ in limitText(textLimit) }
    }

    //Function to keep text length in limits
    func limitText(_ upper: Int) {
        if username.count > upper {
            username = String(username.prefix(upper))
        }
    }
}
