Implement <code>preferredStatusBarStyle</code> as you mentioned and call <code>self.setNeedsStatusBarAppearanceUpdate()</code> in <code>ViewDidLoad</code> and 
also in Info.plist set <code>UIViewControllerBasedStatusBarAppearance</code> to <code>YES</code> (It's <code>YES</code> by default)

It is not clear why it is not working.I need to check code.One other suggestion is 
go with working code in <code>viewDidLoad</code> <code>UIApplication.sharedApplication().statusBarStyle = .LightContent</code> and change this to default when you view get disappeared <code>viewWillDisappear</code>.

After reading all the suggestions, and trying out a few things, I could get this to work for specific viewcontrollers using the following steps :

First Step:

Open your info.plist and insert a new key named "View controller-based status bar appearance" to NO

Second Step (Just an explanation, no need to implement this):

Normally we put the following code in the application(_:didFinishLaunchingWithOptions:)
method of the AppDelegate, 

Swift 2

<pre><code>UIApplication.sharedApplication().statusBarStyle = .LightContent
</code></pre>

Swift 3

<pre><code>UIApplication.shared.statusBarStyle = .lightContent
</code></pre>

but that affects the <code>statusBarStyle</code> of all the ViewControllers.

So, how to get this working for specific ViewControllers - Final Step:

Open the viewcontroller file where you want to change the <code>statusBarStyle</code> and put the following code in <code>viewWillAppear()</code>, 

Swift 2

<pre><code>UIApplication.sharedApplication().statusBarStyle = .LightContent
</code></pre>

Swift 3

<pre><code>UIApplication.shared.statusBarStyle = .lightContent
</code></pre>

Also, implement the <code>viewWillDisappear()</code> method for that specific viewController and put the following lines of code, 

Swift 2

<pre><code>override func viewWillDisappear(animated: Bool) {
 super.viewWillDisappear(animated)
 UIApplication.sharedApplication().statusBarStyle = UIStatusBarStyle.Default

}
</code></pre>

Swift 3

<pre><code>override func viewWillDisappear(_ animated: Bool) {
 super.viewWillDisappear(animated)
 UIApplication.shared.statusBarStyle = UIStatusBarStyle.default
}
</code></pre>

This step will first change the <code>statusBarStyle</code> for the specific viewcontroller and then change it back to <code>default</code> when the specific viewcontroller disappears. Not implementing the <code>viewWillDisappear()</code> will change the <code>statusBarStyle</code> permanently to the new defined value of <code>UIStatusBarStyle.LightContent</code>

In your Info.plist you need to define View controller-based status bar appearance to any value.

If you define it YES then you should override preferredStatusBarStyle function in each view controller.

If you define it NO then you can set style in AppDelegate using 

<pre><code>UIApplication.sharedApplication().setStatusBarStyle(UIStatusBarStyle.LightContent, animated: true)
</code></pre>

<code>Stars</code> View Controller is a <code>CPBaseNavigationController</code>,and <code>CPBaseNavigationController</code> is subclass of <code>UINavigationController</code>.

I try doing the next setps:

<li>In <code>AppDelegate.swift</code> func <code>didFinishLaunchingWithOptions</code>,add 

<pre><code>//change status bar color
UIApplication.sharedApplication().statusBarHidden = false
UIApplication.sharedApplication().statusBarStyle = .LightContent

<li>In StoryBoard,find the <code>Base Tab BarController</code>(picture on the above).select <code>Attributes Inspector</code>, change the <code>Sattus Bar</code> attribute to <code>Light Content</code>.so bad,no effect.</li>
</ol>

<ol start="3">
<li>Last I get it.In my custom navigation controller <code>CPBaseNavigationController</code>,add func <code>preferredStatusBarStyle</code>

<pre><code>override func preferredStatusBarStyle() -&gt; UIStatusBarStyle {
 return .LightContent
}
</code></pre>

It works well!</li>
</ol>

Besides,<code>statusBarStyle</code> deprecated in 9.0,you can use <code>-[UIViewController preferredStatusBarStyle]</code>.

I can suggest you a simpler way,

<ol>
<li>Just call <a href="https://developer.apple.com/reference/uikit/uiviewcontroller/1621354-setneedsstatusbarappearanceupdat" rel="nofollow noreferrer">setNeedsStatusBarAppearanceUpdate</a> in viewDidLoad as Apple docs says, </li>
</ol>

<blockquote>
 Call this method if the view controller's status bar attributes, such as hidden/unhidden status or style, change. If you call this method within an animation block, the changes are animated along with the rest of the animation block.
</blockquote>

<ol start="2">
<li>Implement <a href="https://developer.apple.com/reference/uikit/uiviewcontroller/1621416-preferredstatusbarstyle" rel="nofollow noreferrer">preferredStatusBarStyle</a> returning your preferred type.</li>
</ol>

It worked for me in iOS 10.1.

Objective C

<pre><code>[self setNeedsStatusBarAppearanceUpdate];

-(UIStatusBarStyle)preferredStatusBarStyle {
 return UIStatusBarStyleLightContent;
}
</code></pre>

Swift

<pre><code>setNeedsStatusBarAppearanceUpdate()

var preferredStatusBarStyle: UIStatusBarStyle { 
 return .lightContent
}
</code></pre>

I am surprised nobody pointed this out. Anyway enjoy :)

I had some trouble with this one. I didn't really feel good about globally changing the status bar color in view did appear and then changing it back on view did disappear like the accepted answer. Believe it or not you can get this working by overriding <code>preferredStatusBarStyle</code> on your desired view controller. After much time this is what I did to get it working:

<ol>
<li>Change View controller-based status bar appearance in your <code>info.plist</code> to YES.</li>
<li>Now any full screen view controller can change the status bar style by overriding <code>preferredStatusBarStyle</code>.</li>
<li>I specify full screen because this will not work for (non-full screen) modal view controllers, not without setting <code>modal​Presentation​Captures​Status​Bar​Appearance</code> to Yes that is.</li>
<li>Also if you have embedded view controllers, like in a navigation controller for example, it will ask the top most view controller for status bar style. Overriding <code>child​View​Controller​For​Status​Bar​Style</code> and passing the embedded view controller is supposed to work but it didn't for me. So I just returned the embedded view controllers preferred status bar as the preferred status bar style. Something like this:

<pre><code>override var preferredStatusBarStyle: UIStatusBarStyle {
 if let topViewController = viewControllers.last {
 return topViewController.preferredStatusBarStyle
 }

 return .default
}
</code></pre></li>
</ol>

Swift 4.2 solution with NavigationController

First Step:

Open your info.plist and insert a new key named "View controller-based status bar appearance" or <code>UIViewControllerBasedStatusBarAppearance</code> to YES to let each VC use their own status property.

Second Step 

In each VC, override the preferredStatusBarStyle property like this :

<pre><code>override var preferredStatusBarStyle : UIStatusBarStyle {
 return .lightContent //.default for black style
}
</code></pre>

Last step

Override the preferredStatusBarStyle property in your custom NavigationController class :

<pre><code>class NavigationController : UINavigationController {

override var preferredStatusBarStyle : UIStatusBarStyle {

 if let topVC = viewControllers.last {
 //return the status property of each VC, look at step 2
 return topVC.preferredStatusBarStyle 
 }

 return .default
}
</code></pre>

blocks|key|2721941|text|要做到这一点，另一种非常简单的方法是创建UINavigationController类的扩展。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2721942|因为重写preferredStatusBarStyle:方法不会在中工作，除非是，所以我们在UINavigationController类中这样做。|offset|length|style|CODE|BOLD|2721943|++++extension+UINavigationController+{

Another really easy way to make this work is just to create an extension of the UINavigationController class.

Since overriding the <code>preferredStatusBarStyle:</code> method wont work UNLESS we do it inside of the UINavigationController class.

<pre><code> extension UINavigationController {
 open override var preferredStatusBarStyle: UIStatusBarStyle {
 return .lightContent
 }
 }

SWIFT 4.2
Hey, I wanted to share a solution, that worked for me that I got from a great article on this ellusive subject by Graig Grummitt. 

Step 1
As others have mentioned ADD below to your PLIST

<pre><code>View controller-based status bar appearance YES
</code></pre>

Step 2 in the RootViewcontroller add below

<pre><code>var statusBarHidden: Bool = false {
 didSet(newValue) {
 UIView.animate(withDuration: 0.1) {
 self.setNeedsStatusBarAppearanceUpdate()
 }
 }
 }

 override var prefersStatusBarHidden: Bool {
 return statusBarHidden
 }

 var vcStatusBarStyle: UIStatusBarStyle = .default {
 didSet(newValue) {
 UIView.animate(withDuration: 0.1) {
 self.setNeedsStatusBarAppearanceUpdate()
 }
 }
 }

 override var preferredStatusBarStyle: UIStatusBarStyle {
 return vcStatusbarStyle
 }
</code></pre>

When updating either property <code>statusBarHidden</code> or <code>vcStatusBarStyle</code> it will call <code>setNeedsStatusBarAppearanceUpdate()</code> and will update the status bar with the new values for either <code>prefersStatusBarHidden</code> or <code>preferredStatusBarStyle</code>. In my situation I had to update these properties for the container viewcontroller, that was the parent of the visable childviewcontroller. I did this using a simple delegate method. 

<pre><code>protocol MainViewControllerDelegate {
 func updateStatusBarStyle(statBarStayle: UIStatusBarStyle)
 func toggleStatusBar(visable: Bool)
}
</code></pre>

Ofcourse when instantiating the childViewController(Visible VC) don't forget to set the MainViewcontroller(Container VC) as its delegate. I sometimes do. :)

<pre><code>childViewController.delegate = self
</code></pre>

Then in the childViewController I just called the delegate method when needed to update the status bar. 

<pre><code>self.delegate?.updateStatusBarStyle(statBarStayle: .default)
</code></pre>

As mentioned above Graig Grummitt goes into more detail about this solution and also working with UINavigationControllers as well.

WARNING

<hr>

Setter for 'statusBarStyle' was deprecated in iOS 9.0: Use -[UIViewController preferredStatusBarStyle]

<pre><code>UIApplication.shared.statusBarStyle = .default
</code></pre>

<hr>

so my solution was as this:
making an extension from the navigation controller:

<pre><code>extension UINavigationController {
 open override var preferredStatusBarStyle: UIStatusBarStyle {
 if let topViewController = presentedViewController{
 return topViewController.preferredStatusBarStyle
 }
 if let topViewController = viewControllers.last {
 return topViewController.preferredStatusBarStyle
 }

 return .default
 }
}
</code></pre>

and if you have a viewController that will have another style than the style of the app , you can make this 

<pre><code>var barStyle = UIStatusBarStyle.lightContent
override var preferredStatusBarStyle: UIStatusBarStyle{
 return barStyle
}
</code></pre>

lets say that you app status style is <code>.default</code> and you want this screen to be <code>.lightContent</code>
so barStyle will take the <code>.lightContent</code> as its default value, this will change the status bar style to lightContent, and then make sure when <code>viewWillDisappear</code> change the barStyle again to the app status bar style which in our case is <code>.default</code> .

this is works for me

2) Override the preferredStatusBarStyle property in your custom NavigationController class : (from @guillama)

<pre><code>class NavigationController : UINavigationController {

 override var preferredStatusBarStyle : UIStatusBarStyle {

 if let topVC = viewControllers.last {
 //return the status property of each VC, look at step 2
 return topVC.preferredStatusBarStyle 
 }
 return .default
 }
</code></pre>

3) override <code>preferredStatusBarStyle</code> in your specific view controller:

<pre><code>override var preferredStatusBarStyle : UIStatusBarStyle {
 return .lightContent
}
</code></pre>

2.hidden navigation bar

1) ditto

2) don't need second step above, you should implement third step directly.

<pre><code>override var preferredStatusBarStyle : UIStatusBarStyle {
 return .lightContent
}
</code></pre>

I use this way in Swift 5, Swift 4.2.

Add next values to Info.plist:

UIViewControllerBasedStatusBarAppearance = YES

or

UIViewControllerBasedStatusBarAppearance = NO (to see changes)

UIStatusBarHidden = NO

UIStatusBarStyle = UIStatusBarStyleDefault (or set to UIStatusBarStyleLightContent if you want to see light status bar texts on launching)

<a href="https://i.stack.imgur.com/diddT.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/diddT.png" alt="Info.plist"></a>

Then place code below to specific view controllers where you want to see light content (to see dark texts set preferredStatusBarStyle to .darkContent).

<pre><code>override var preferredStatusBarStyle: UIStatusBarStyle {
 return .lightContent
}

override func viewDidLoad() {
 super.viewDidLoad()

 if let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as? UIView {

(As of June 10, 2020)

Swift 5 (Without editing <code>.Plist</code> file)

If you are using <code>Storyboard</code>, go to the <code>NavigationController</code>, select the <code>navigationBar</code>, click on the <code>Attributes Inspector</code>, then change the <code>style</code>. if you need <code>light content</code> (white status bar) set it anything except <code>default</code> lets say set style <code>black</code> And if you want <code>dark content</code> (black status bar) set it <code>default</code>. 

The default (<code>UIBarStyleDefault</code>) results in the dark foreground <code>UIStatusBarStyleDefault</code> status bar. And <code>UIBarStyleBlack</code> will give a <code>UIStatusBarStyleLightContent</code> status bar.

Programatically 

<pre><code>let nav = UINavigationController(rootViewController: rootViewController)

 nav.navigationBar.barStyle = .default //gives you dark Content status bar

 nav.navigationBar.barStyle = .black //gives you light content status bar
</code></pre>

Without Navigation Bar (Edit <code>.Plist</code>)

add <code>UIViewControllerBasedStatusBarAppearance</code> / <code>View controller-based status bar appearance</code> to your <code>info.plist</code>, and set value is <code>true</code>.

<code>Override</code> the <code>preferredStatusBarStyle</code> property in your Controller

<pre><code>class ViewController: UIViewController {
 override var preferredStatusBarStyle : UIStatusBarStyle {
 return .lightContent
 }
}
</code></pre>

If you want to set it to all view controllers in the app. and if your app has a navigation controller.
You can do it in the plist file as follow:
<a href="https://i.stack.imgur.com/wCQE9.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/wCQE9.png" alt="plist file changes" /></a>

<pre><code>override func preferredStatusBarStyle() -&gt; UIStatusBarStyle {
 return UIStatusBarStyle.LightContent;
}
</code></pre>

Using the above code in any ViewController to set the statusBar color to White for a specific viewcontroller doesnt work in iOS8 for me. Any suggestions? Using the UIApplication.sharedApplication method, the color changes after required changes in the Info.plist for the whole app.

<pre><code>// Change the colour of status bar from black to white
UIApplication.sharedApplication().statusBarStyle = .LightContent
</code></pre>

How can I just make changes to the status bar color for some required and specific ViewControllers?
