UITextView created programatically does not scroll

I created the following textview using the interface builder and it scrolled. However the same setup does not scroll if done programmatically. I created a demo project to demonstrate this.

In my view controller this is what I have. 

import UIKit

class ViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()

    let customTextView = CustomTextView(frame: CGRect(x: 0,
                                                      y: 0,
                                                      width: 400,
                                                      height: 400))

    customTextView.center = self.view.center


    self.view.addSubview(customTextView)
}

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }
}

In the custom text view class this is what I have. 

import Foundation
import UIKit


class CustomTextView: UIView {

    override init(frame: CGRect) {

        super.init(frame: frame)

        setLayout()
    }

    required init?(coder aDecoder: NSCoder) {
         super.init(coder: aDecoder)
    }

    private var imageView: UIImageView?
    private var textView: UITextView?

    private func setLayout() {


        imageView = .init()
        textView = .init()

        imageView?.frame = self.frame
        textView?.frame = CGRect(x: (imageView?.frame.size.width)! * 0.5,
                             y: (imageView?.frame.size.height)! * 0.5,
                            width: 200,
                            height: 200)

        textView?.clipsToBounds = true
        textView?.font = UIFont.systemFont(ofSize: 16)
        textView?.isEditable = false
        textView?.preservesSuperviewLayoutMargins = false

        textView?.text = """
    Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque aliquam gravida lobortis. Quisque mollis varius sollicitudin. Maecenas pharetra consectetur nunc et imperdiet.

        imageView?.addSubview(textView!)
        textView?.center = (imageView?.center)!
        self.addSubview(imageView!)
   }
}

You have added the textView to the imageView. The UImageView's userInteraction is disabled by default. Add the below code after imageView's init and it should work fine.

imageView?.isUserInteractionEnabled = true

Now you should be able to scroll. Hope it helps.
