TaskManager

TaskManager is a cache for asynchronous tasks in Swift. It allows you to manage the execution of tasks with a simple API that lets you add, cancel, and wait for tasks.

Usage

Creating a TaskManager

To create a TaskManager, simply instantiate it with a key type that conforms to Hashable. It is recommended to use an enum as the key type to avoid typos and ensure type safety:

enum TaskKey: Hashable {
    case fetchUserData(userId: String)
    case downloadFile(url: URL)
}

let taskManager = TaskManager<TaskKey>()

Adding a Task

To add a new task to the TaskManager, use the task(key:priority:operation:) method. The key parameter is the unique identifier for the task, priority is the priority of the task (optional), and operation is the async operation to be performed:

taskManager.task(key: .fetchUserData(userId: "1234"), priority: .high) {
    // Perform async operation to fetch user data
    return userData
}

Retrieving a Task Result

To retrieve the result of a task, use the value(for:as:) method. The for parameter is the key of the task, and as is the type of the result you expect to receive:

let userData = try await taskManager.value(for: .fetchUserData(userId: "1234"), as: UserData.self)

or

let userData: UserData = try await taskManager.value(for: .fetchUserData(userId: "1234"))

Canceling a Task

To cancel a task, use the cancel(key:) method:

taskManager.cancel(key: .fetchUserData(userId: "1234"))

Canceling All Tasks

To cancel all tasks, use the cancelAll() method:

taskManager.cancelAll()
