Swift PKCE is a lightweight collection of commonly used, client-side code generations in an OAuth 2.0 Authorization Code flow + PKCE implemented in Swift. Each function conforms to the RFC 7636 protocol.
Due to the dependency on Apple CryptoKit, Swift PKCE is available to the following platforms:
iOS 13.0+
iPadOS 13.0+
macOS 10.15+
Mac Catalyst 15.0+
tvOS 15.0+
watchOS 8.0+
Import the Swift PKCE framework by adding it to the imports at the top of the file:
import PKCEgenerateCodeVerifier
Generates a new, random code verifier with a specified length of characters.
func generateCodeVerifier(length: Int = 128) throws -> String {generateCodeChallenge
Generates a code challenge for a given code verifier.
func generateCodeChallenge(for: String) throws -> StringThe original code for Swift PKCE was sourced from a Bootstragram blog post written by @dirtyhenry and updated slightly.
