Problems with ApolloInterceptor.

[Jensileus]

Body

I am new to swift, but i have used Apollo in other project, so I am well known with it. I want to add it to my project, but i just get the same error all the time. Example: Type 'TokenInterceptor' does not conform to protocol 'ApolloInterceptor' and here is the code? //Interceptor for adding tokens
import Apollo

class TokenInterceptor: ApolloInterceptor {

let token: String

init(token: String) {
    self.token = token
}

func interceptAsync<Operation>(
    chain: RequestChain,
    request: HTTPRequest<Operation>,
    response: HTTPResponse<Operation>?,
    completion: @escaping (Result<GraphQLResult<Operation.Data>, Error>) -> Void) where Operation : GraphQLOperation {
        request.addHeader(name: "Authorization", value: "Bearer: \(token)")
        print(request.additionalHeaders)
        chain.proceedAsync(request: request, response: response, completion: completion)
}

}
