@Gerzer Hello!
This is where the error occurred.

as you see i tried to convert error to MoyaError but it doesn't work

guard let errorCode = (error as? MoyaError)?.response?.statusCode else {
              // error as? MoyaError is nil
                    if let moyaError = (error as? MoyaError), moyaError.errorCode == 6 {
              
                        return Single.error(api.errorMap[1009] ?? error)
                    }
                    
    return Single.error(error)
}

Swift doesn’t (yet) have typed errors, so the compiler can’t guarantee that all errors that a Moya function might throw will indeed be MoyaError instances. Your code should be able to handle all errors, whether or not they’re MoyaError instances.

@Gerzer Hmm.. Then How Can i use statusCode on error ??

You can only get the statusCode property if the error type is indeed a MoyaError instance. If it’s not a MoyaError instance, then there won’t be any statusCode property.

Example usage:

do {
    // Make a request…
} catch let moyaError as MoyaError {
    let statusCode = moyaError.respone?.statusCode
    // Do something with the status code…
} catch {
    // It’s not a Moya error, so there’s no statusCode property
}
