+@Metadata {

+
+## Overview
+
+`hasDynamicIsland` is a property of [`ByDevice`](<doc:ByDevice>) that can provide a non-hardcoded boolean value of whether or not a device has the Dynamic Island
+
+> Warning: It is unknown when this property of `ByDevice` was added, and to which operating systems, testing is required before production use. `ByDevice` and/or `hasDynamicIsland` may be removed at any time.
+
+## Method
+
+We can use this code to get the future-proof boolean:
+```swift
+let BYDeviceClass = NSClassFromString( "BYDevice") as! NSObject.Type
+let bydevice = BYDeviceClass.perform(NSSelectorFromString("currentDevice")).takeUnretainedValue() as! NSObject
+let hasDynamicIsland = bydevice.value(forKey: "hasDynamicIsland") as! Bool
+
+print(hasDynamicIsland)
+```
