Segue very slow on first call in iOS

Question

I have a few simple Segues --> Show(e.g. Push)

On some Segues the first time calling the Segue I get a delay (about 2 Seconds).

There is no Code being Executed on shouldPerformSegue and prepare.

ViewDidLoad of the next View gets called after the Delay.

When the delay occurs I often get this warning:

objc[3993]: Class PLBuildVersion is implemented in both...

There seems to be no solution to this though --> Link

I have also tried calling the Segue Manually like this:

DispatchQueue.main.async {
    self.performSegue(withIdentifier: "theIdentifier", sender: theSender)
}

Is there any way to make this more responsive?

Thanks!

Are you perform heavy UI task of calling webservice in viewdidload or viewwillappear? — Bista, Dec 08 '16 at 10:46

@Mr.Bista Nah, also viewDidLoad gets called after the delay. — eljoe, Dec 08 '16 at 11:07
It can be your next viewcontroller have heavy rendering or heavy execution on `viewDidLoad`, reduce it and try again, I have the same issue with the next viewcontroller contains webview, so i move the webview load to other function — Tj3n, Dec 08 '16 at 11:11
