## Description

Nimble is a matcher framework and assertion library designed for Swift and Objective-C unit tests. It extends standard testing frameworks to provide a domain-specific language for writing descriptive and readable assertions.

The project provides utilities for behavior driven development and asynchronous state verification. This includes the ability to wait for expressions to match specific values over a set period of time to verify timing-dependent behavior.

The framework covers general test automation and validation for Swift and Objective-C projects, allowing developers to compare code expression outcomes against expected values.
