You can change the size by overriding the frame method for cursor as follows,

class CustomTextField: UITextField {

    override func caretRect(for position: UITextPosition) -> CGRect {
        var rect = super.caretRect(for: position)
        let size = CGSize(width: 10, height: 50)
        // Calculating center y
        let y = rect.origin.y - (size.height - rect.size.height)/2
        rect = CGRect(origin: CGPoint(x: rect.origin.x, y: y), size: size)
        return rect
    }
}

Set CustomTextField class in xib/storyboard identity inspector for that textField.
