SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps developers implement Clerk authentication correctly in native Swift and iOS apps without guessing at SDK behavior, setup requirements, or flow structure.

Core Features & Use Cases

  • Native iOS Auth Setup: Configure ClerkKit for SwiftUI or UIKit apps using a direct publishable key and source-guided implementation patterns.
  • Prebuilt or Custom Flows: Choose ClerkKitUI AuthView for fast combined sign-in and sign-up, or build a custom multi-step flow that stays close to ClerkKitUI behavior.
  • Setup Compliance: Audit and apply required iOS quickstart prerequisites such as associated domains, app capabilities, and Apple sign-in requirements when needed.
  • Use Case: A team building a new iPhone app can use this Skill to add Clerk authentication, verify the project matches the latest iOS setup guidance, and avoid flow or capability mistakes.

Quick Start

Use this skill to determine the right Clerk iOS auth flow for your project, verify the required setup, and implement the matching native Swift configuration.

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

To implement Clerk authentication in native SwiftUI, configure the ClerkKit package with a direct publishable key and utilize ClerkKitUI for prebuilt AuthView flows or build custom sign-in experiences.

Can I use ClerkKit for iOS authentication in UIKit projects, or is it only for SwiftUI?

Yes, you can use ClerkKit for UIKit projects. The native iOS implementation supports both SwiftUI and UIKit, allowing you to integrate prebuilt or custom authentication flows in either framework.

What iOS setup prerequisites are required to configure Clerk sign-in correctly?

Configuring Clerk sign-in requires setting up associated domains, enabling necessary app capabilities, and applying Apple sign-in requirements to ensure your project matches the latest iOS quickstart guidance.

Does Clerk authentication for native iOS work with React Native or Expo apps?

No, native Clerk authentication for Swift and iOS explicitly excludes Expo and React Native apps. This implementation is designed specifically for native SwiftUI and UIKit projects using the Clerk iOS package.

What is the best way to build a custom Clerk sign-up flow in Swift?

The best way to build a custom Clerk sign-up flow in Swift is to implement a multi-step process that maintains source-guided parity with ClerkKitUI behavior, ensuring consistent authentication logic.

Why do I need a direct publishable key for ClerkKit setup in my iOS app?

A direct publishable key is required for ClerkKit setup to establish a secure connection between your native iOS app and Clerk's authentication services, enabling proper initialization of sign-in and sign-up components.
