SegueAddition
Easily way to write perfromSegue(withIdentifier:sender).
Usage
You can call performSegue with closure.
let customString = "CustomString"
performSegue("SegueIdentfiier") { segue in
guard let toViewController = segue.destinationViewController as? CustomViewController else {
fatalError()
}
toViewController.string = customString
}It has the same meaning.
...
let customString = "CustomString"
performSegueWithIdentifier("SegueIdentfiier", sender: customString)
...
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
guard let toViewController = segue.destinationViewController as? CustomViewController,
customString = sender as? String
where segue.identifier == "SegueIdentfiier"
else {
fatalError()
}
toViewController.string = customString
}So, no need to write prepare(for segue: UIStoryboardSegue, sender: Any?) again.
And, It is read and write easy for perform segue event and passing value to next view controller.
