Introduction

Quick is a BDD framework for Swift and Objective-C. Tests are organised with describe, context and it blocks into examples and example groups.

It comes with Nimble, a matcher framework that replaces unclear XCTAssert() statements with readable expectations such as expect(sections).to(contain("Installing Quick")) and asynchronous ones like toEventually(beTruthy()).

The source code is at Quick/Quick on GitHub under the Apache-2.0 licence, with about 9,800 stars; the most recent commit was on 17 March 2026.

Quick specs work best when the describe and context blocks read like a sentence about behaviour. Keep each example focused on one expectation, and use Nimble’s asynchronous matchers instead of manual waits for UI or networking code.

Features

1. BDD structure: describe, context and it.
2. Nimble matchers: Readable expectations.
3. Async expectations: toEventually.
4. Objective-C support: Mixed codebases.

Pros

1. Free to use: Open source under the Apache-2.0 licence, so the core tool costs nothing to use.
2. Actively maintained: The repository had commits as recent as 17 March 2026.
3. Community: About 9,800 GitHub stars.

Cons

1. Swift Testing overlap: Apple’s new framework covers some use cases.

      }
    }
  }
}

Conclusion

Quick and Nimble remain a popular, readable way to write Swift tests.

On CheckOps, Quick is filed under the Unit testing stage. Related tools listed here include XCTest, Swift Testing, SnapshotTesting (Point-Free), Kotest, RSpec and ViewInspector. A short trial on a real project, with your own code, data and pipeline, is usually the fastest way to choose between them, because fit matters more than feature lists.
