Get Completion isn't working

[Veeit]

Hey Guys,

I'm currently trying to implement getStream with SwiftUI. But I'm experience a wired behaviour of feed.get(). The completion isn't running. But I get the response printed inside the console, with mean that I get the correct response from the backend.

My Code:

Client.config = .init(apiKey: "apiKey-is-hidden",
                                  appId: "97497",  logsEnabled: true)

            Client.shared.setupUser(token: "token-is-hidden", completion: { result in
                    guard result.error == nil else {
                        preconditionFailure("Cannot setup user: \(result.error!)")
                    }

                if let feedId = FeedId(feedSlug: "site") {
                    let timelineFlatFeed = Client.shared.flatFeed(feedId)
                    print("time line: ==== \(timelineFlatFeed)")

                    let seconds = 4.0
                    DispatchQueue.main.asyncAfter(deadline: .now() + seconds) {
                        timelineFlatFeed.get(enrich: true, pagination: .limit(2)) { response in
                            if (result.error != nil) {
                                print("error")
                            } else {
                                print("result")
                            }
                        }
                    }
                }

            })

Hello @Veeit ,

You need to hold a strong reference to timelineFlatFeed.

Try this:

Client.config = .init(apiKey: "apiKey-is-hidden",
                                  appId: "97497",  logsEnabled: true)

let timelineFlatFeed = Client.shared.flatFeed(feedId)

            Client.shared.setupUser(token: "token-is-hidden", completion: { result in
                    guard result.error == nil else {
                        preconditionFailure("Cannot setup user: \(result.error!)")
                    }

                if let feedId = FeedId(feedSlug: "site") {
                    let timelineFlatFeed = Client.shared.flatFeed(feedId)
                    print("time line: ==== \(timelineFlatFeed)")

                    let seconds = 4.0
                    DispatchQueue.main.asyncAfter(deadline: .now() + seconds) {
                        timelineFlatFeed.get(enrich: true, pagination: .limit(2)) { response in
                            if (result.error != nil) {
                                print("error")
                            } else {
                                print("result")
                            }
                        }
                    }
                }

            })

Hello @b-onc ,

same result. I tried this code now:

Client.config = .init(apiKey: "ztyjtywyeb28",
                                  appId: "97497",  logsEnabled: true)

            Client.shared.setupUser(token: "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyX2lkIjoiLTEifQ.4ttgLiot0zNIy1YOqENZz3YfsCLU3oej9n7l-m5Vcrw", completion: { result in
                    guard result.error == nil else {
                        preconditionFailure("Cannot setup user: \(result.error!)")
                    }
            })

            let timelineFlatFeed = Client.shared.flatFeed(feedSlug: "site")!

            print("time line: ==== \(timelineFlatFeed)")

            timelineFlatFeed.get(pagination: .limit(2)) { response in
                print("===========")
                print("===========")
                print("===========")
                print("===========")
                print("===========")

                if (response.error != nil) {
                    print("error")
                } else {
                    print("result")
                }

                print("===========")
                print("===========")
                print("===========")
                print("===========")
                print("===========")
            }

and got his console log:

the completion handler of .get is still not working.

[matteing]

Facing this issue too. Any help?

Hello @Veeit @matteing ,

You need to hold a strong reference to the feed object for its completion to be called. If you're holding a strong reference but still seeing this issue, can you share a sample project?

ios.zip

I don't know where you see a weak reference.

Hello @Veeit Thanks for the sample project. There are a couple of issues with it:

1. Client configuration must be done once, on app start, preferably in scene(_,willConnectTo:)
2. You should wait for the result of setupUser to call feed.get
3. In the project you've shared, timelineFlatFeed is a local variable, which is deallocated after the lifetime of the closure its in (onAppear(perform:)). You should hold a reference to the timelineFlatFeed so it's not deallocated until gets completion is ran.

I've made these changes and I can see that get completion runs as expected.
