Can't Hide Status Bar—Swift 3, [duplicate]

Question

I usually hide the status bar with

override func prefersStatusBarHidden() -> Bool {
    return true
}

but Xcode is giving me an error, saying "Method does not override anything from its superclass".

If I delete the override, Xcode gives a different error: "Method 'prefersStatusBarHidden()' with Objective-C selector 'prefersStatusBarHidden' conflicts with getter for 'prefersStatusBarHidden' from superclass 'UIViewController' with the same Objective-C selector"

I also have "Hide Status Bar" checked in my Target's general settings:

but the status bar still shows up.

---

I found this method in another Stack Overflow answer

UIApplication.shared.setStatusBarHidden(true, with: .none)

but that doesn't hide the status bar either.

In Xcode 8 Beta 1, I used the first and second methods, which worked to hide the status bar (the first method did not return an error). What can I do now to hide the status bar, with Xcode 8 Beta 4?

Note: The status bar shows up on Simulator devices and physical devices, all running iOS 10.

Answer 1

We need to override the property itself on Swift 3 (this is new in Xcode 8 Beta 4):

override var prefersStatusBarHidden: Bool {  
    return true  
}

updated Swift 5+

override var prefersStatusBarHidden: Bool { true }

for another example also you can get here and here
