Improvements to Unit Testing in Swift with Xcode 7

This article discusses improvements to unit testing in Swift introduced with Xcode 7, announced at WWDC 2015. It explains how the @testable keyword allows unit tests to access all internal and public types and members without modifying access modifiers. The article summarizes the simple three-step process: code types with default internal access, add @testable import ModuleName to test files, and begin testing. It also references older articles for Xcode 6.x users and emphasizes understanding over copying code.
