Dealing with errors in 5.0.0

Hi,

i am using your library in storyboard project (not using swiftUI) , how can I call the api to get user , I saw your example :

Endpoint.user(secret.identifier)
            .unlock(with: secret)
            .session(.instagram)
            .sink { <#Subscribers.Completion<Error>#> in
                <#code#>
            } receiveValue: { User.Unit in
                <#code#>
            }

receiveValue closure is not optional , how can I check if api failed to get user for identifier ?

Never mind I figured it out.
Is there any workaround if I don't want to call .store(in: &bin) at the end, how can i avoid warning?

You need to retain your call somehow, using a Set<AnyCancellable> is the easiest/most compact way.

Keep in mind that if you don't retain your sinked Publisher the request is immediately cancelled.

If you need to find out more about Combine Publishers, sinks, Cancellables, etc. there's a lot of good content online, as this is not immediately related to Swiftagram.

I'm still gonna add a reply for future reference, in case anybody else wonders.

// Make sure this is retained!
var bin: Set<AnyCancellable> = []

Endpoint.user(secret.identifier)
            .unlock(with: secret)
            .session(.instagram)
            .sink { 
               switch $0 {
               case .failure(let error): break
               default: break
               }
            } receiveValue: { 
               print("output", $0)
            }
            .store(in: &bin)
