• Concurrency boundaries
• Actors

🛠 DX Improvements: Simplified Decoding of Complex Claims

🔹 Claim.data Property

A new data property is available for complex claims (arrays and dictionaries only):

// Returns Data for arrays and dictionaries
let data = jwt["custom_object"].data

// Returns nil for primitives (use .string, .integer, etc. instead)
let primitiveData = jwt["email"].data // nil

🔹 Claim.decode(_:) Method

Decode complex claims directly into Decodable types:

struct Address: Decodable {
    let street: String
    let city: String
}

// Decode a custom claim
let address = try jwt["address"].decode(Address.self)
