A super slim Swift library that solves nested async code by chaining blocks instead of nesting them.
Me is a lightweight Swift library that solves the problem of nested asynchronous computations, often called 'callback hell'. It allows developers to chain async operations linearly instead of nesting closures, improving code readability and maintainability. The library provides explicit control over execution flow with methods like `runNext()` and `end()`.
Swift developers building iOS or macOS applications with complex async logic, such as cloud-based apps or multi-step API calls.
Developers choose Me for its minimal footprint (under 200 lines) and straightforward API that doesn't require learning a new paradigm like Promises. It integrates seamlessly with Grand Central Dispatch and offers fine-grained control over async flow without heavy abstraction.

With under 200 lines of code, Me is lightweight and easy to audit, reducing integration complexity as emphasized in the README.
Replaces nested closures with a chainable .next API, making multi-step async operations more readable and maintainable.
Built on Grand Central Dispatch for thread-safe execution and custom queue support, ensuring reliability in concurrent environments.
Methods like runNext() and end() provide fine-grained management over async execution, giving developers full control over the flow.
Forgetting to call end() can lead to memory leaks, requiring diligent developer oversight, as warned in the README's cons section.
Parameters must be stored in a shared dictionary instead of passed directly between blocks, adding boilerplate and reducing type safety.
Lacks mechanisms for automatic error propagation or recovery, forcing developers to implement manual checks in each block.
