Quick is a behavior-driven development framework for Swift and Objective-C. Inspired by RSpec, Specta, and Ginkgo.

// Swift

import Quick
import Nimble

class TableOfContentsSpec: QuickSpec {
  override func spec() {
    describe("the 'Documentation' directory") {
      it("has everything you need to get started") {
        let sections = Directory("Documentation").sections
        expect(sections).to(contain("Organized Tests with Quick Examples and Example Groups"))
        expect(sections).to(contain("Installing Quick"))

      context("if it doesn't have what you're looking for") {
        it("needs to be updated") {
          let you = You(awesome: true)


Quick comes together with Nimble — a matcher framework for your tests. You can learn why XCTAssert() statements make your expectations unclear and how to fix that using Nimble assertions here.

Swift Version

Certain versions of Quick and Nimble only support certain versions of Swift. Depending on which version of Swift your project uses, you should use specific versions of Quick and Nimble. Use the table below to determine which versions of Quick and Nimble are compatible with your project.

All documentation can be found in the Documentation folder, including detailed installation instructions for CocoaPods, Carthage, Git submodules, and more. For example, you can install Quick and Nimble using CocoaPods by adding the following to your Podfile:

# Podfile


target "MyApp" do
  # Normal libraries

  abstract_target 'Tests' do
    inherit! :search_paths
    target "MyAppTests"
    target "MyAppUITests"

    pod 'Quick'
    pod 'Nimble'
