CoachNow/AppsFlyerFramework ? reverse-engineered prompt

Build me a small Swift package that makes it easy for an app to use AppsFlyer tracking without having to wire up a bunch of setup every time.

I want it to feel like a clean framework I can drop into an iOS project, with a simple way to configure the SDK, start it, and send basic events or attribution data. Please keep the public API easy to understand, add sensible defaults, and include a few examples or usage notes so I know how to call it from an app.

If anything about the latest AppsFlyer setup has changed, look up the current docs online and follow the recommended approach. Also make sure the package is organized cleanly, builds successfully, and is ready to be reused in other projects.
