AWSMobileClient Crash when app starts about aws-mobile-appsync-sdk-ios

Thanks for reporting this. Can you provide some additional details such as your config with sensitive information removed and the code snippet you're using to initialize the AppSync client? Without the ability to reproduce this issue, this will be difficult to diagnose.

@ameter Thanks for your reply.

Here is our configuration code:

["UserAgent": "aws-amplify/cli",
                "Version": "0.1.0",
                "IdentityManager": ["Default": [:]],
                "AppSync": [
                    "Default": [
                        "ApiUrl": apiUrl,
                        "Region": "aws-region",
                        "AuthMode": "AMAZON_COGNITO_USER_POOLS",
                        "ClientDatabasePrefix": "Application_AMAZON_COGNITO_USER_POOLS"
                    ]
            ],
                "CredentialsProvider": [
                    "CognitoIdentity": [
                        "Default": [:]
                    ]
            ],
                "CognitoUserPool": [
                    "Default": [
                        "PoolId": poolId,
                        "AppClientId": appClientId,
                        "AppClientSecret": appClientSecret,
                        "Region": "aws-region"
                    ]
            ],
                "Auth": [
                    "Default": ["authenticationFlowType": "USER_SRP_AUTH"]
            ]
        ]

As for our initialization code, here's a draft of how we initialize the client:

public final class MobileClient {

    private var mobileClient: AWSMobileClient?

    private var appSyncClient: AWSAppSyncClient?

func getMobileClient() -> AWSMobileClient? {
let client = AWSMobileClient(configuration: configuration)
client.initialize { [weak self] userState, error in
            if let error = error {
                return nil
            }
            
            guard self?.appSyncInit(cognitoUserPoolsAuthProvider: client) == true else {
                return nil
            }
            
            do {
            appSyncClient = try AWSAppSyncClient(cognitoUserPoolsAuthProvider: client)
        } catch {
            return nil
        }
            DispatchQueue.main.async {
                client.addUserStateListener(self) { userState, _ in
            switch userState {
            case .guest:
                //print log
                
            case .signedOut:
                 //print log
                
            case .signedIn:
                 //print log
                
            case .signedOutUserPoolsTokenInvalid:
                //print log
                self.signOut { error in
                    if let error = error {
                         //print log
                    }
                }
                
            case .signedOutFederatedTokensInvalid:
                 //print log
                
            default:
                 //print log
            }
        }
            }
        }
}
mobileClient = client
return client
}

Please let m know if there are any more information I can provide.
