How to detect if the device (iphone) has physical home button?

Question

How to detect in Swift if the current device (iPhone) has a physical home button or hasn't, like: iPhone X, iPhone Xs, iPhone Xs Max, iPhone Xr ?

Answer 1

For iOS 13 and higher:

    var isBottom: Bool {
    if #available(iOS 13.0, *), UIApplication.shared.windows[0].safeAreaInsets.bottom > 0 {
        return true
    }
    return false
}

Answer 2

Check the safe area:

if @available(iOS 11.0, *), 
    UIApplication.sharedApplication.keyWindow?.safeAreaInsets.bottom > 0 {
    return true
}
return false

Swift 4.2 version:-

var isBottom: Bool {
    if #available(iOS 11.0, *), let keyWindow = UIApplication.shared.keyWindow, keyWindow.safeAreaInsets.bottom > 0 {
        return true
    }
    return false
}

You can also check the device type (check out this post), but checking the safe area is probably the easiest way.
