Creating a developer tool - part 1

As Swift developers, we often require easily accessible developer tools.
Similar to my LifetimeTracker, you might desire a draggable button that can be pinned to screen edges and is responsive to screen changes.

This series of articles aims to guide you through the process of creating a new dev tool and we'll start with just that: an overlay button that acts as an access point to a tool that we will be developing in the subsequent articles. Our primary target platforms are iOS and macOS.
