Background tasks in iOS can be managed efficiently using the BGTaskScheduler API. To implement BGTaskScheduler in a Swift project, your project structure can be organized to enhance readability and maintainability. Below is a recommended project structure along with an example of how to set up and schedule background tasks.
import UIKit
import BackgroundTasks
@main
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
BGTaskScheduler.shared.register(forTaskWithIdentifier: "com.yourapp.bgTask",
using: nil) { task in
self.handleAppRefresh(task: task as! BGAppRefreshTask)
}
return true
}
func handleAppRefresh(task: BGAppRefreshTask) {
// Schedule your next task here
scheduleAppRefresh()
// Perform the task
let queue = OperationQueue()
queue.maxConcurrentOperationCount = 1
// Configure and add your operations here
task.setTaskCompleted(success: true)
}
func scheduleAppRefresh() {
let request = BGAppRefreshTaskRequest(identifier: "com.yourapp.bgTask")
request.earliestBeginDate = Date(timeIntervalSinceNow: 15 * 60) // Schedule for 15 minutes later
do {
try BGTaskScheduler.shared.submit(request)
} catch {
print("Could not schedule app refresh: \(error)")
}
}
}
