Question

I've created a modal segue to a viewController, however when i trigger this segue, there seem to be some delay when viewing the viewController. All i have in the viewController is in the viewDidLoad. what could course this slow modal segue?
override func viewDidLoad() {
super.viewDidLoad()
self.title = "Caption".uppercaseString
self.view.backgroundColor = UIColor(hexString: "#0B1E30")
self.navigationController?.navigationBar.barTintColor = UIColor(gradientStyle: UIGradientStyle.LeftToRight, withFrame: CGRectMake(0, 0, self.view.frame.width, (self.navigationController?.navigationBar.frame.height)! + 20), andColors: [UIColor(hexString: "#7F5CE6"), UIColor(hexString: "#9D8FE2")])
let closeButton = UIBarButtonItem(image: UIImage(named: "Cross"), style: UIBarButtonItemStyle.Done, target: self, action: "dismissController")
self.navigationItem.leftBarButtonItem = closeButton
textView?.text = "Add caption (optional)"
textView?.becomeFirstResponder()
textView?.keyboardAppearance = UIKeyboardAppearance.Dark
textView?.font = UIFont(name: "Montserrat-Light", size: 13)
textView?.textColor = UIColor(hexString: "#363636")
capturedImageView = UIImageView(image: capturedPhoto)
capturedImageView?.frame = CGRectMake(8,10, 85, 85)
let path = UIBezierPath(rect: CGRectMake(8, 10, 85, 85))
textView?.textContainer.exclusionPaths = [path]
textView?.addSubview(capturedImageView!)
facebookButton?.tag = 1
facebookButton!.adjustsImageWhenHighlighted = false
facebookButton?.addTarget(self, action: "tapSocial:", forControlEvents: UIControlEvents.TouchUpInside)
facebookButton?.tintColor = UIColor.whiteColor()
facebookButton?.backgroundColor = UIColor(hexString: "#395798")
facebookButton?.contentMode = UIViewContentMode.Center
facebookButton?.setTitle("", forState: UIControlState.Normal)
let fBorder = CALayer()
let width = CGFloat(1.0)
fBorder.borderColor = UIColor.whiteColor().colorWithAlphaComponent(0.05).CGColor
fBorder.frame = CGRect(x: 0, y: facebookButton!.frame.size.height - width, width: facebookButton!.frame.size.width, height: facebookButton!.frame.size.height)
fBorder.borderWidth = width
facebookButton!.layer.addSublayer(fBorder)
facebookButton!.layer.masksToBounds = true
twitterButton?.tag = 2
twitterButton!.adjustsImageWhenHighlighted = false
twitterButton?.addTarget(self, action: "tapSocial:", forControlEvents: UIControlEvents.TouchUpInside)
twitterButton?.contentMode = UIViewContentMode.Center
twitterButton?.tintColor = UIColor.whiteColor()
twitterButton?.setTitle("", forState: UIControlState.Normal)
let tBorder = CALayer()
tBorder.borderColor = UIColor.whiteColor().colorWithAlphaComponent(0.05).CGColor
tBorder.frame = CGRect(x: 0, y: twitterButton!.frame.size.height - width, width: twitterButton!.frame.size.width, height: twitterButton!.frame.size.height)
tBorder.borderWidth = width
twitterButton!.layer.addSublayer(tBorder)
twitterButton!.layer.masksToBounds = true
let tRightBorder = CALayer()
tRightBorder.borderColor = UIColor.whiteColor().colorWithAlphaComponent(0.05).CGColor
tRightBorder.frame = CGRect(x: 0, y: 0, width: width, height: twitterButton!.frame.size.height)
tRightBorder.borderWidth = width
twitterButton!.layer.addSublayer(tRightBorder)
instagramButton?.tag = 3
instagramButton!.adjustsImageWhenHighlighted = false
instagramButton?.addTarget(self, action: "tapSocial:", forControlEvents: UIControlEvents.TouchUpInside)
instagramButton?.contentMode = UIViewContentMode.Center
instagramButton?.tintColor = UIColor.whiteColor()
instagramButton?.setTitle("", forState: UIControlState.Normal)
let iBorder = CALayer()
iBorder.borderColor = UIColor.whiteColor().colorWithAlphaComponent(0.05).CGColor
iBorder.frame = CGRect(x: 0, y: instagramButton!.frame.size.height - width, width: instagramButton!.frame.size.width, height: instagramButton!.frame.size.height)
iBorder.borderWidth = width
instagramButton!.layer.addSublayer(iBorder)
instagramButton!.layer.masksToBounds = true
let iLeftBorder = CALayer()
iLeftBorder.borderColor = UIColor.whiteColor().colorWithAlphaComponent(0.05).CGColor
iLeftBorder.frame = CGRect(x: 0, y: 0, width: width, height: instagramButton!.frame.size.height)
iLeftBorder.borderWidth = width
instagramButton!.layer.addSublayer(iLeftBorder)
}

This came as a surprise for me but apparently there is a performance issue with textView's property "selectable" when set to true by default (checked on Storyboard).
Try going to your Storyboard, select each textView and uncheck the box "selectable". If you need the textView to be selectable, then just set selectable to true programatically on your viewDidLoad.
