Might I propose a change to the enum?

typedef NS_ENUM(NSUInteger, UIBackgroundStyle) {
    UIBackgroundStyleDefault,
    UIBackgroundStyleTransparent,
    UIBackgroundStyleLightBlur,
    UIBackgroundStyleDarkBlur,
    UIBackgroundStyleDarkTranslucent
};

A friend wanted to use it in Swift, an enums are properly imported to Swift with this syntax.

@dariolass, it has not been removed as of iOS 9.0.2.

In addition to what @ThePantsThief suggested, there are a few enum values that are actually left out that can make really nice blurs: https://gist.github.com/AppleBetas/4ddf91c8ead4b2a87a71bcd52eab258b
