Initializing the SDK

To use the SDK’s methods and classes, your application must call the SDK’s initialize method to initialize the MobileCredentialVerifier class:


func initialize(
    platformConfiguration: PlatformConfiguration? = nil,
    loggerConfiguration: LoggerConfiguration = LoggerConfiguration()
) throws

Configure verifier for app-to-app verification

You can configure MATTR VII platform parameters in the SDK to enable app-to-app verification using the PlatformConfiguration structure:

Platform Configuration


        do {
            try mobileCredentialShared
                .initialize(
                    platformConfiguration: PlatformConfiguration(
                        tenantHost: URL(string: platformConfigurations.tenantHost), // Tenant subdomain
                        applicationId: platformConfigurations.applicationId // ID of web application that will be used for verification
                    )
                )
        }
        catch {
            print(error.localizedDescription)
        }

Configure logger behavior

You can configure the SDK’s logger behavior using the optional loggerConfiguration parameter:

Configure logger behavior


    init() {
        do {
            let loggerConfiguration = LoggerConfiguration(
                logLevel: .Debug,
                callbackLogLevel: .Debug) { event in
                    print(
                        "Perform any custom action with the log event: \(event.message)"
                    )
                }
 
            mobileCredentialVerifier = MobileCredentialVerifier.shared
            try mobileCredentialVerifier
                .initialize(
                    loggerConfiguration: loggerConfiguration
                )
        } catch {
            print(error)
        }
    }

logLevel : Determines which events are written to log files:
callbackLogLevel : Determines which events invoke the callback function:
callback : Defines the function to call when events defined by callbackLogLevel occur.

Logging levels

These levels apply to both the logLevel and callbackLogLevel parameters (corresponding raw value in shown in parenthesis):

Off (0).
Error (1).
Warning (2).
Info (3).
Debug (4).
Verbose (5).
