How to display array elements in UITextField in swift 3?

Question

I want to display the button.tag value in UITextField. For that I append the tapped button value in array. I initialized the array on top as

var inputString:Array = [String]()

Now I tried to put these array values in UITextField like this

        self.txtPassword.text = self.inputString

I tried this as I did earlier in objective c. But in swift I am unable to do this. Please someone give me solution. Thanks

Can you show your Objective-C code, and perhaps a sample of what you expect the value of the text field to be? — Scott Thompson

just inputString.joined() or inputString.joined(withSeparator: ", ") — Leo Dabus

This is my objective - c code [self.inputPassowrd appendString:[NSString stringWithFormat:@"%ld", (long)button.tag]]; self.txtPassword.text = self.inputPassowrd; — Sptibo

You are trying to attribute an array to a String. That will never work.

If you need one value of the array to be attributed to the textField, you need to know its index and do:

self.txtPassword.text = self.inputString[index]
