#Constructor
Configure and construct your Magic SDK instance.
#Magic
| Public constructors | |
| Magic(apiKey: String) | Construct a Magic instance with publishable API Key retrieved from the Magic Dashboard |
| Magic(apiKey: String, network: EthNetwork) | Construct a Magic instance with publishable Key and Ethereum network |
| Magic(apiKey: String, customNode: CustomNodeConfiguration) | Construct a Magic instance with publishable Key and Custom Node configuration |
#Example
In AppDelegate
import MagicSDK
import UIKit
@UIApplicationMainfunc application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// assign the newly created Magic instance to shared property
// Test key defaults to "rinkeby", live key defaults to "mainnet"
Magic.shared = Magic("YOUR_PUBLISHABLE_API_KEY");
return true
}#Auth Module
The Auth Module and its members are accessible on the Magic SDK instance by the auth property.
import MagicSDK
let magic = Magic.shared
magic.auth;
magic.auth.loginWithMagicLink;
#loginWithMagicLink
Authenticate a user passwordlessly using a "magic link" sent to the specified user's email address.
#Public Methods
| Methods |
| loginWithMagicLink( _ configuration: LoginWithMagicLinkConfiguration, response: (_ resp: Response<String>) -> Void ) |
| loginWithMagicLink(_ configuration: LoginWithMagicLinkConfiguration) -> Promise <String> |
#Returns
Promise<string | null>: The promise resolves upon authentication request success and rejects with a specific error code if the request fails. The resolved value is a Decentralized ID token with a default 15-minute lifespan.
#Example
Closure

}#Associated Class
LoginWithMagicLinkConfiguration(showUI: Bool = true, email: String)
emailThe user email to log in with.showUIIftrue, show an out-of-the-box pending UI while the request is in flight.
#User Module
The User Module and its members are accessible on the Magic SDK instance by the user property.
import MagicSDK
let magic = Magic.shared

magic.user.getMetadata
magic.user.updateEmail
magic.user.isLoggedIn
magic.user.logout
#updateEmail

#Public Methods
| Methods |
| updateEmail( _ configuration: UpdateEmailConfiguration, response: (_ resp: Response<Bool>) -> Void ) |
| updateEmail(_ configuration: UpdateEmailConfiguration) -> Promise <Bool> |
#Returns
Promise<Bool>: The promise resolves with a true boolean value if update email is successful and rejects with a specific error code if the request fails.
#Example
import MagicSDK
class MagicViewController: UIViewController {
let magic = Magic.shared
// Initiates the flow to update a user's current email to a new one.
func updateEmail() {
guard let magic = magic else { return }
// Assuming user is logged in

}#Associated Class
UpdateEmailConfiguration(showUI: Bool = true, email: String)
emailThe user email to update with.showUIIftrue, show an out-of-the-box pending UI while the request is in flight.
#getIdToken

#getMetadata
Retrieves information for the authenticated user.

#Returns
UserMetadata: containing the issuer, email and cryptographic public address of the authenticated user.
public struct UserMetadata: MagicResponse {
public let issuer: String?
public let publicAddress: String?
public let email: String?
}issuer: The Decentralized ID of the user. In server-side use-cases, we recommend this value to be used as the user ID in your own tables.email: Email address of the authenticated user.publicAddress: The authenticated user's public address (a.k.a.: public key). Currently, this value is associated with the Ethereum blockchain.
