what's meaning of "GBDeviceInfo"

I get two errors during compile.

        static let version = UIDevice.currentDevice().systemVersion.floatValue

error: "Value of type 'String' has no member 'floatValue'"

    return GBDeviceInfo.deviceInfo().modelString

error: "Use of unresolved identifier 'GBDeviceInfo'"

@KimBin and @oddmagne:
replace
static let version = UIDevice.currentDevice().systemVersion.floatValue
with
static let version = (UIDevice.currentDevice().systemVersion as NSString).floatValue

Also add https://github.com/lmirosevic/GBDeviceInfo to your project.

@imkevinxu: very cool utility! Thanks a lot :)

Works great, except from what I can see deviceHeight only works if the device is in portrait; otherwise in landscape, you'll get the height of the display (which is the width of the device).

static var TheCurrentDeviceHeight: CGFloat {
    struct Singleton {
        static let height = max(UIScreen.mainScreen().bounds.size.height, UIScreen.mainScreen().bounds.size.width)
    }
    return Singleton.height
}

... should do it
