How to add text to the canvas, like in the Liang's brush App in the app store.

Here's how i did it. I created a view controller with a textview. And on save action or delegate method of textview, computed the size of the text in the textview.

Here's the code snippet if somebody needs.

let font = UIFont.systemFont(ofSize: 16)
let fontAttributes = [NSAttributedString.Key.font: font]
let myText = textView.text
let textsize = (myText! as NSString).size(withAttributes: fontAttributes)
        
let size = CGSize(width: textsize.width+10, height: self.textView.contentSize.height+10)
UIGraphicsBeginImageContextWithOptions(size, false, 0);
self.textView.drawHierarchy(in: CGRect(x: 0, y: 0, width: self.textView.frame.size.width, height: self.textView.frame.size.height),afterScreenUpdates:true)
let screenShot:UIImage = UIGraphicsGetImageFromCurrentImageContext() ?? UIImage()

consider the resultant screenshot below.

This will give you an image with a screenshot of the text. Then you can create a charlet/texture out of this image (For this you can take help from the sampel code.)
