Immediate tasks in Swift Concurrency explained

This article covers immediate tasks in Swift Concurrency, introduced in Swift 6.2 via SE-472. It explains how Task.immediate differs from regular tasks by executing synchronously on the caller's executor until the first suspension point, reducing overhead for minimal work or when already on the correct actor. The article includes code examples, discusses use cases like performance-sensitive code and synchronous APIs, and warns against overuse. It also contains a promotional mention for MCP Beast, a tool for managing MCPs in AI apps.
