Status bar height in Swift

Question

How can I get the status bar's height programmatically in Swift?

In Objective-C, it's like this:

[UIApplication sharedApplication].statusBarFrame.size.height.

Answer 1

Is there any problems with Swift 2.x:

UIApplication.sharedApplication().statusBarFrame.size.height

Swift 3 or Swift 4:

UIApplication.shared.statusBarFrame.height

Make sure UIKit is imported

import UIKit

In iOS 13, you will get a deprecated warning"

'statusBarFrame' was deprecated in iOS 13.0: Use the statusBarManager property of the window scene instead.

To fix this:

let height = view.window?.windowScene?.statusBarManager?.statusBarFrame.height ?? 0

Answer 2

Updated Answer Supporting iOS 13+ and older iOS Versions for Swift 5

 func getStatusBarHeight() -> CGFloat {
    var statusBarHeight: CGFloat = 0
    if #available(iOS 13.0, *) {
        let window = UIApplication.shared.windows.filter {$0.isKeyWindow}.first
        statusBarHeight = window?.windowScene?.statusBarManager?.statusBarFrame.height ?? 0
    } else {
        statusBarHeight = UIApplication.shared.statusBarFrame.height
    }
    return statusBarHeight
}

Happy Coding!

Answer 3

This is what I use:

struct Screen {

 static var width: CGFloat {
  return UIScreen.main.bounds.width
 }

 static var height: CGFloat {
  return UIScreen.main.bounds.height
 }

 static var statusBarHeight: CGFloat {
  let viewController = UIApplication.shared.windows.first!.rootViewController
  return viewController!.view.window?.windowScene?.statusBarManager?.statusBarFrame.height ?? 0
 }

}

Then you can do:

Screen.statusBarHeight

Swift is just a different language. The API elements are the same. Perhaps something like this:

let app = UIApplication.sharedApplication()
let height = app.statusBarFrame.size.height
