UITextView Dynamic Width With Text iOS

Need some help. I'm building a chat app and want the chat textView to adjust with the width of the text so if the message is short the textView adjusts accordingly. I'm using autolayout but can't seem to figure out how to dynamically adjust the constraint's constant based on the textView's text line length. Thanks.

How I have it now:

Programmatically you can do like,

Objective C 

- (void)textViewDidChange:(UITextView *)textView {
    CGFloat fixedWidth = textView.frame.size.width;
    CGSize newSize = [textView sizeThatFits:CGSizeMake(fixedWidth, MAXFLOAT)];
    CGRect newFrame = textView.frame;
    newFrame.size = CGSizeMake(fmaxf(newSize.width, fixedWidth), newSize.height);
    textView.frame = newFrame;
}

Swift

let fixedWidth = textView.frame.size.width
textView.sizeThatFits(CGSize(width: fixedWidth, height: CGFloat.greatestFiniteMagnitude))
let newSize = textView.sizeThatFits(CGSize(width: fixedWidth, height: CGFloat.greatestFiniteMagnitude))
var newFrame = textView.frame
newFrame.size = CGSize(width: max(newSize.width, fixedWidth), height: newSize.height)
textView.frame = newFrame;
