a couple of option, and this could be a problem that is a bug, but in the mean time, have you tried this:
Option 1:
info.plist, set up the option in your info.plist for "Status bar style", this is a string value with the value of "UIStatusBarStyleLightContent"
Also, in your infor.plist, set up the variable "View controller-based status bar appearance" and set it's value to "NO"
Then, in each view controller in your app, explicitly declare the following in command in your initializers, your ViewWillAppear, and your ViewDidLoad
UIApplication.sharedApplication().statusBarStyle = UIStatusBarStyle.LightContent
Option 2:
In your info.plist set up the option for "Status bar style" to "UIStatusBarStyleLightContent". Also, in your infor.plist, set up the variable "View controller-based status bar appearance" and set it's value to "YES"
Then, in each view controller place the following methods
override func preferredStatusBarStyle() -> UIStatusBarStyle {
return UIStatusBarStyle.LightContent;
}
override func prefersStatusBarHidden() -> Bool {
return false
}
Also, you may need to do something like this:
self.extendedLayoutIncludesOpaqueBars = true
Also, I translated it to Swift code for you
