swift 3 check if iphone 6/7 and 6/7plus display is in standard or zoomed mode

Question

I wonder how I can check if the user has the display set to zoomed mode.

I have tried this:

public var isZoomed: Bool {
    return UIScreen.main().scale < UIScreen.main().nativeScale
}

And also:

#define IS_OS_8_OR_LATER    ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
#define IS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
#define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
#define IS_IPHONE_5 (IS_IPHONE && ([[UIScreen mainScreen] bounds].size.height == 568.0) && ((IS_OS_8_OR_LATER && [UIScreen mainScreen].nativeScale == [UIScreen mainScreen].scale) || !IS_OS_8_OR_LATER))
#define IS_STANDARD_IPHONE_6 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 667.0  && IS_OS_8_OR_LATER && [UIScreen mainScreen].nativeScale == [UIScreen mainScreen].scale)
#define IS_ZOOMED_IPHONE_6 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 568.0 && IS_OS_8_OR_LATER && [UIScreen mainScreen].nativeScale > [UIScreen mainScreen].scale)
#define IS_STANDARD_IPHONE_6_PLUS (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 736.0)
#define IS_ZOOMED_IPHONE_6_PLUS (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 667.0 && IS_OS_8_OR_LATER && [UIScreen mainScreen].nativeScale < [UIScreen mainScreen].scale)

But I none of them works.

So is there a way to detect if the device is zoomed or even force it to not be zoomed when the app is running?

Working swift 3 solution:

if (UIScreen.main.bounds.size.height == 667.0 && UIScreen.main.nativeScale < UIScreen.main.scale) {
    print("iphone 6 plus")
} else {
    print("none zoomed 6 plus")
}
        
if (UIScreen.main.bounds.size.height == 568.0 && UIScreen.main.nativeScale > UIScreen.main.scale) {
    print("zoomed iphone 6")
} else {
    print("none zoomed")
}
