🔒 We conclude our series by exploring the mode of main actor by default. New Xcode projects come with with setting turned on, so it's important to know the ins and outs of working with it, and how it is affected by "sendable" protocols.

🔒 The `sending` keyword has special behavior when applied to closure arguments, as well as `inout` arguments. We will employ our knowledge of "disconnected" and "task-isolated" regions to get an understanding for how they work, why nested closures are problematic, and how a throwback from our second episode can help us grapple with `inout sending`.

🔒 The `sending` parameter is a powerful concurrency tool new to Swift 6 that allows you to precisely specify how non-sendable values can cross isolation boundaries. We will explore how it works in terms of "region-based isolation," and how we can send values into and out of functions as "disconnected" objects that are free to travel across isolation boundaries.
