I am using Apollo Client subscriptions for my app. I follow the codes here on the documentation from Apollo https://www.apollographql.com/docs/ios/subscriptions but I keep having an error on when I subscribe to the apollo subscription

Value of type 'Apollo.Cancellable' does not conform to 'Combine.Cancellable' in assignment

Here is my code

self.subscription = ApolloNetwork.shared.apollo
            .subscribe(subscription: UserBalanceSubscription()) { [weak self] result in
            guard let self = self else {
                return
            }
            
            switch result {
            case .success(let graphQLResult):
                print(graphQLResult)
            case .failure(let error):
                print("error: \(error)")
            }
        }

Here is how I declare the var subscription

private var subscription: Cancellable?

I am getting confused what causing the issue and how to fix it.

CodePudding user response：

It sounds like you have a naming collision between modules (Apollo and Combine) that both have a Cancellable type defined.

You can explicitly declare that you want this Cancellable to be the one from Apollo by doing the following:

private var subscription: Apollo.Cancellable?
