FeedListKit

FeedListKit is a high level framework for representing data from an Api inside a SwiftUi List. It automatically handles refreshing and loading more on scroll.

How to use

Create the Api

First, you need to create an api which conforms to the Api protocol. FeedListKit automatically sends a page parameter to your api, you need to handle paging directly in your api.

FeedListKit works great with NetworkKit:

class MyApi: Api {
    static func fetchRows<T>(_ urlString: String, parameters: [String : String]?, type: T.Type) async -> [T]? where T : Model {
        do {
            return try await NKHttp.getObjectArray(urlString, parameters: parameters, type: type)
        } catch {
            return nil
        }
    }
    
    static func fetchRows<T>(_ urlString: String, parameters: [String : String]?, type: T.Type, callback: @escaping ([T]?) -> ()) where T : Model {
        NKHttp.getObjectArray(urlString, parameters: parameters, type: type, callback: callback)
    }
}

But you can also fetch the data on your own:

class MyApi: Api {
    static func fetchRows<T>(_ urlString: String, parameters: [String : String]?, type: T.Type) async -> [T]? where T : Model {
        // Fetch your data and return the object array asynchronously.
        // You can use URLSession or some other http library.
    }
    
    static func fetchRows<T>(_ urlString: String, parameters: [String : String]?, type: T.Type, callback: @escaping ([T]?) -> ()) where T : Model {
        // Fetch your data and return the object array with callback.
        // You can use URLSession or some other http library.
    }
}

Create a model for your data

The model needs to conform to the Model protocol.

struct Animal: Model {
    var id: String
    var name: String
}

Create a FeedNetworking

Create your first FeedNetworking and pass your object Model and your Api type.

class MyAnimalFeedNetworking: FeedNetworking<Animal, MyApi> {
    // The url to your api endpoint
    override var apiUrl: String {
        "http://mydomain.com/api/animals"
    }
    
    // Your parameters
    override var httpParameters: [String : String] {
        [
            "myKey": myValue
        ]
    }
}

Use FeedList

struct MyAnimals: View {

    init() {
        self._feedNetworking = StateObject(wrappedValue: MyAnimalFeedNetworking())
    }

    @StateObject private var feedNetworking: MyAnimalFeedNetworking

    var body: some View {
        FeedList(feedNetworking: feedNetworking, row: { animal in
            Text(animal.wrappedValue.name)
        }, loadingView: {
            Text("Fetching animals ...")
        }, noDataView: {
            Text("No Animals found! :(")
        })
        .task {
            await feedNetworking.fetch()
        }
    }
}
