Crashing always

[stephen-talari]

Always crashes at line 243
let window: UIWindow = UIApplication.sharedApplication().keyWindow! with error fatal error: unexpectedly found nil while unwrapping an Optional value

i am calling following code in my viewController in viewDidLoad() method SweetAlert().showAlert("Good job!", subTitle: "You clicked the button!", style: AlertStyle.Success)

@stephen-talari I solved, if you call SweetAlert in ViewDidLoad it crash, i tried in viewdidappear and a button action it worked fine. Happy coding

There is no keyWindow at that point. I would add replace the following

let window: UIWindow = UIApplication.sharedApplication().keyWindow! with:

guard let window: UIWindow = UIApplication.sharedApplication().keyWindow! else { return }
