I don't have specific information on how async/await handles priority inversion from the provided context. However, I can share that Swift's concurrency model, including async/await, is designed to improve the handling of asynchronous operations by allowing tasks to suspend and yield the CPU to other tasks. This helps in managing resources efficiently and can potentially mitigate issues like priority inversion by ensuring that tasks are executed in a more predictable and controlled manner.

A Swift Tour: Explore Swift’s features and design
Learn the essential features and design philosophy of the Swift programming language. We’ll explore how to model data, handle errors, use protocols, write concurrent code, and more while building up a Swift package that has a library, an HTTP server, and a command line client. Whether you’re just beginning your Swift journey or have been with us from the start, this talk will help you get the most out of the language.
Migrate your app to Swift 6
Experience Swift 6 migration in action as we update an existing sample app. Learn how to migrate incrementally, module by module, and how the compiler helps you identify code that’s at risk of data races. Discover different techniques for ensuring clear isolation boundaries and eliminating concurrent access to shared mutable state.
Go further with Swift Testing
Learn how to write a sweet set of (test) suites using Swift Testing’s baked-in features. Discover how to take the building blocks further and use them to help expand tests to cover more scenarios, organize your tests across different suites, and optimize your tests to run in parallel.
