#if Macro in swift to checking device

i am defining the macro at my Appdelegate , here is my code 

let IPHONE = UIDevice.currentDevice().userInterfaceIdiom == .Phone
let IPAD = UIDevice.currentDevice().userInterfaceIdiom == .Pad
#if IPHONE
    let LEFT_DRAWER_HEIGHT : CGFloat = 270.0
    #elseif IPAD
let LEFT_DRAWER_HEIGHT : CGFloat = 404.0
    #else
let LEFT_DRAWER_HEIGHT : CGFloat = 404.0
    #endif

but it always returns LEFT_DRAWER_HEIGHT = 404.0 rather i have run in iphone device. whats the mistake? can anyone figure it out.

Do you have separate targets for iPhone and iPad? And are you defining those constants in each of those targets?

#if is a compile time conditional, so if you have a universal app, the compiler can't know at compile time what device will the app run on. You should instead use a normal if condition.
