SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill removes the guesswork of wiring Clerk authentication into native Swift/iOS projects by aligning implementation with the actual ClerkKitUI source behavior and required iOS quickstart setup.

Core Features & Use Cases

  • Native iOS Clerk integration: Implements Clerk authentication for native Swift/iOS apps (SwiftUI/UIKit patterns) using ClerkKit and ClerkKitUI source-guided behavior.
  • Flow choice with guardrails: Guides you through either a prebuilt (AuthView/sheet-based) flow or a custom flow that preserves AuthView step/layout parity.
  • Environment-driven capability handling: Uses the installed ClerkKitUI Environment field semantics and checks /v1/environment to determine required capabilities (including Apple sign-in enablement logic).

Quick Start

Use clerk-swift when you have a native iOS (non-Expo, non-React Native) project and you want to implement Clerk authentication for either prebuilt AuthView or a custom ClerkKit-based flow.

FAQPage Schema
How do I implement Clerk authentication in a native iOS Swift app?

Implement Clerk authentication in native iOS apps by mirroring ClerkKitUI behavior, enforcing quickstart prerequisites, choosing an AuthView flow, and supplying a real Clerk publishable key.

Can I use Clerk prebuilt AuthView flows in SwiftUI or UIKit projects?

Yes, Clerk prebuilt AuthView sheet-based flows work in SwiftUI and UIKit projects, and you can also build custom flows preserving AuthView step and layout parity.

Does Clerk authentication for iOS require setting up associated domains?

Yes, Clerk authentication on iOS requires configuring the associated-domain webcredentials entry to complete the clerk-ios README quickstart prerequisites.

What is the Clerk Environment API used for in iOS authentication?

The Clerk Environment API is used by inspecting installed ClerkKitUI Environment semantics and calling /v1/environment to determine required capabilities like Apple sign-in enablement logic.

Can I use this Clerk iOS authentication approach for Expo or React Native projects?

No, this Clerk authentication approach is specifically for native Swift and iOS projects and does not apply to Expo or React Native projects.
