Swift library for validating IBOutlet and IBAction connections in iOS/macOS storyboards and XIBs.
Outlets is a Swift library that provides utility functions for validating IBOutlet and IBAction connections in iOS and macOS applications. It solves the problem of broken or misconfigured Interface Builder links by enabling developers to write automated tests that verify storyboard and XIB connections are correctly established.
iOS and macOS developers using Swift and Interface Builder (storyboards/XIBs) who want to ensure their UI connections are reliable through automated testing.
Developers choose Outlets because it offers a simple, focused way to catch Interface Builder connection errors early, integrates seamlessly with testing frameworks like Quick and Nimble, and reduces manual verification of UI links.
Utility functions for validating IBOutlet and IBAction connections
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides specific assertion functions like BarButtonItemOutletAssertion for different UI components, reducing type-casting errors and ensuring accurate connection checks.
Designed to work seamlessly with Quick and Nimble, as shown in the example code, making it easy to incorporate into behavior-driven test suites.
Enables automated testing of IBOutlet and IBAction connections, catching misconfigurations before they cause runtime crashes in production.
Focuses solely on connection validation without adding bloat, as emphasized in the philosophy of preventing mistakes without unnecessary complexity.
Built for Swift 2.2+, which may not be compatible with newer Swift versions without updates, limiting adoption in modern projects using Swift 5+.
Only supports storyboards and XIBs, excluding newer UI frameworks like SwiftUI, making it irrelevant for teams adopting contemporary Apple development practices.
Optimized for Quick and Nimble; integrating with other frameworks like XCTest requires additional setup, as seen in the custom action validator configuration in examples.
