create jwt token in swift

Here's an example of how to create a JWT token in Swift using the SwiftJWT library:

main.swift
import SwiftJWT

// Define your JWT claims
let claims = MyClaims(name: "John Doe", isAdmin: true)

// Sign the JWT token using a secret key
let signer = JWTSigner.hs256(key: "mySecretKey".data(using: .utf8)!)
let jwt = try JWT<MyClaims>(claims: claims).sign(using: signer)

// The resulting JWT token
print(jwt) // eyJhbGciOiAiSFMyNTYiLCAidHlwIjogIkpXVCJ9.eyJzdWIiOiAiMTIzNDU2Nzg5MCIsICJuYW1lIjogIkpvaG4gRG9lIiwgImlzQWRtaW4iOiB0cnVlfQ.LW8x9X1ABKozZrEPMooATugW3cL-3IYngyKtTAbewGs

In this example, we create a JWT token with a MyClaims custom claim that includes the name of the user and whether they have admin privileges. We then use the JWTSigner.hs256 method to sign the token using a secret key. Finally, we print out the resulting JWT token.

Note that you will need to install the SwiftJWT library using a package manager, such as CocoaPods or Swift Package Manager, before you can use it in your Swift project.
