Increasing text size of textView leads to smaller text | Swift iOS

I tried to build a textView with two buttons to in/decrease the size of the text. I used:

textView.font = UIFont(name: "System", size: 50)

But no matter which number I set for the size, the text always becomes the same size (around 11) when calling the method.

Why is that? Could you help me with that?

If you would like to do something you said, you can make your own category like this:

extension UITextView {
    func increaseFontSize () {
        self.font =  UIFont(name: self.font!.fontName, size: self.font!.pointSize+4)!
    }
}

To use it just import it like this:

textview.increaseFontSize()

This will increase your text by 4.
