Widget update data properly - swiftui

Question

I've made a widget which fetches Codable data and it's working just fine in the simulator ONLY. The widget updates within 30 seconds or less after the data has changed. I've set a 5 minute update limit (I understand it's called far less frequently). It's working actually really great in the simulator without any kind of background data fetches and updates in less time than I set in getTimeline. Then I ran into an issue on a a real test device.
The data won't update anywhere between 2-10+ mins while testing a real device, in the snapshot it's updated and can see the new data changes but not in the widget on springboard. I don't understand why the simulator works just fine but not a real device. The Widget is definitely being updated when the data changes but only in the Simulator so am I suppose to fetch data in the background?
I've come across this Keeping a Widget Up To Date | Apple Developer Documentation. I'm still very new to Swift and SwiftUI so this is a little bit harder for me to grasp. I'm trying to understand the section Update After Background Network Requests Complete to update my Codeable data. My guess is the simulator is different from a real device and I need to fetch data in the background for the must up to date data?
The end goal is to have the widget update as frequently as possible with the most current data. I'm not sure I even need the background data fetch?
My data model for my widget as an example (which is working fine)
class DataModel {
var data: DataClass = DataClass(results: []))
func sessions(_ completion: #escaping (DataClass -> Void) {
guard let url = URL(string: "URL HERE") else { return }
var request = URLRequest(url: url)
request.addValue("application/json", forHTTPHeaderField: "Accept")
URLSession.shared.dataTask(with: request) { data, response, error in
if let data = data {
if let response = try? JSONDecoder().decode(DataClass.self, from: data) {
self.data = response
completion(self.data)
WidgetCenter.shared.reloadTimelines(ofKind: "Widget")
}
}
}
.resume()
}
}
My getTimeline calling the data model
func getTimeline(in context: Context, completion: #escaping (Timeline<Entry>) -> ()) {
let model = DataModel()
var entries: [SimpleEntry] = []
let currentDate = Date()
let entryDate = Calendar.current.date(byAdding: .minute, value: 5, to: currentDate)!
let entry = SimpleEntry(date: entryDate, model: model)
entries.append(entry)
model.sessions {_ in
let timeline = Timeline(entries: entries, policy: .atEnd)
completion(timeline)
}
}
I have this for my background network request
import Foundation
import WidgetKit
class BackgroundManager : NSObject, URLSessionDelegate, URLSessionDownloadDelegate {
var completionHandler: (() -> Void)? = nil
private lazy var urlSession: URLSession = {
let config = URLSessionConfiguration.background(withIdentifier: "widget-bundleID")
config.sessionSendsLaunchEvents = true
return URLSession(configuration: config, delegate: self, delegateQueue: nil)
}()
func update() {
let task = urlSession.downloadTask(with: URL(string: "SAME URL FROM DATA MODEL HERE")!)
task.resume()
}
func urlSession(_ session: URLSession ,downloadTask: URLSessionDownloadTask, didFinishDownloadingTo location: URL) {
print (location)
}
func urlSessionDidFinishEvents(forBackgroundURLSession session: URLSession) {
self.completionHandler!()
WidgetCenter.shared.reloadTimelines(ofKind: "Widget")
print("Background update")
}
}
Then in my Widget I set .onBackgroundURLSessionEvents(). I never see any background updates or errors in the console. This seems very wrong, the Codable data will never be updated? How do I properly update my data in the background?
struct Some_Widget: Widget {
let kind: String = "Widget"
let backgroundData = BackgroundManager()
var body: some WidgetConfiguration {
StaticConfiguration(kind: kind, provider: Provider()) { entry in
SomeWidget_WidgetEntryView(entry: entry)
}
.configurationDisplayName("Widget")
.description("Example widget.")
.onBackgroundURLSessionEvents { (sessionIdentifier, completion) in
if sessionIdentifier == self.kind {
self.backgroundData.update()
self.backgroundData.completionHandler = completion
print("background update")
}
}
}
}
