Slow load time for custom UIView with UITextView property in Swift

Question

I originally asked this question. I had assumed that the reason for the slow load time of my custom view was because of layering multiple views on top of each other or perha

downloaded your code from github, why don't you just write a subclass of UITextView instead of the UIView?

import UIKit

class UIMongolTextView_A: UITextView {

    override func awakeFromNib() {
        super.awakeFromNib()
        self.setup()
    }

    func setup() {
        // 1-10: ᠨᠢᠭᠡ ᠬᠤᠶᠠᠷ ᠭᠤᠷᠪᠠ ᠳᠦᠷᠪᠡ ᠲᠠᠪᠤ ᠵᠢᠷᠭᠤᠭ᠎ᠠ ᠳᠤᠯᠤᠭ᠎ᠠ ᠨᠠᠢ᠌ᠮᠠ ᠶᠢᠰᠦ ᠠᠷᠪᠠ

        self.transform = translateRotateFlip()


    }

    /*
    // Only override drawRect: if you perform custom drawing.
    // An empty implementation adversely affects performance during animation.
    override func drawRect(rect: CGRect) {
        // Drawing code
    }
    */
    func translateRotateFlip() -> CGAffineTransform {

        var transform = CGAffineTransformIdentity

        // translate to new center
        transform = CGAffineTransformTranslate(transform, (self.bounds.width / 2)-(self.bounds.height / 2), (self.bounds.height / 2)-(self.bounds.width / 2))
        // rotate counterclockwise around center
        transform = CGAffineTransformRotate(transform, CGFloat(-M_PI_2))
        // flip vertically
        transform = CGAffineTransformScale(transform, -1, 1)

        return transform
    }
}
