No, the Apple Pencil isn't compatible with any of the iPhone versions, first generation, second generation, or newer. In the new update, Apple has limited the use of the Apple Pencil to its supported iPads and eliminated iPhones' ability to detect and make use of its capabilities. The constraint is mostly because of hardware differences – the Pencil is designed to communicate with the iPad's advanced digitizer technology, which the iPhone does not have. This means that regardless of your physical attempts to use the Pencil on an iPhone screen, it will not work as it's supposed to. It'll be easy to handle as a touch object at best, but it won't offer precision input, pressure sensitivity or any of the essential features.
