How to get sharedApplication in Swift on iOS? [duplicate]

Question

How can I get instance of current UIApplication from View Controller in Swift?

I am getting Use of unresolved identifier 'sharedApplication' error with this code:

let app = sharedApplication as UIApplication

Answer 1

EDIT Swift 4.x

let app = UIApplication.shared.delegate as! AppDelegate

If you're e.g. not in a ViewController, you must:

import UIKit

Perhaps try:

let app = UIApplication.sharedApplication()

EDIT (Swift 3):

It should be noted that in Swift 3, to accomplish this, you will want to access the shared property instead:

let app = UIApplication.shared

Answer 2

You can do it by

let app =  UIApplication.sharedApplication()
