CasePaths is a Swift library that extends the key path hierarchy to enum cases, enabling generic inspection and modification of enum case data. It is developed by Point-Free and commonly used as a building block in other Swift libraries such as the Composable Architecture.

Use cases

• get key-path-like access to enum cases in Swift
• write generic code that reads or modifies enum case payloads
• embed and extract enum case data in SwiftUI bindings
• build composable Swift architectures that need enum case optics
• pattern-match enum cases generically in library code

When to choose

• you write Swift libraries that need to abstract over enum cases like key paths do for properties
• you use TCA or other Point-Free libraries that rely on case paths
• you want type-safe, compiler-checked access to enum case associated values

When to avoid

• your project does not use Swift or Apple/Swift ecosystems
• you only need simple switch statements and never need generic enum case access
• you want to avoid third-party dependencies in a small app
