Detect hotspot crashed in iPhone X

Question

I have sample code as below in viewDidLoad to detect hotspot on / off. It working properly in iPhone 6-8 but crashed in iPhone X.

 UIApplication *app = [UIApplication sharedApplication];
    if(![[app valueForKey:@"statusBar"] valueForKey:@"doubleHeightLabel"])
    {
       //Some code here
    }
    else
    {
        //Some code here
    }

Error Message shown:-

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIStatusBar_Modern 0x7ffed341b7f0> valueForUndefinedKey:]: this class is not key value coding-compliant for the key doubleHeightLabel.'

Any idea?

There's a way to check CNCopyCurrentNetowrkInfo for current network info.

And there's hacks:

Obj-c:

CGFloat statusBarHeight = [[UIApplication sharedApplication] statusBarFrame].size.height;

Swift:

let statusBarHeight = UIApplication.shared.statusBarFrame.size.height

With Personal Hotspot enabled, it returns 40, and returns 20 otherwise.

Please note that it's not going to work for iPhone X+
