I'm trying to rewrite a Swift code to Swift 6 language mode and am stuck with this problem. How do I safely pass the bestAttemptContent and contentHandler to the Task? This is from the UNNotificationServiceExtension subclass.
final class NotificationService: UNNotificationServiceExtension {
var contentHandler: ((UNNotificationContent) -> Void)?
var bestAttemptContent: UNMutableNotificationContent?
var customNotificationTask: Task<Void, Error>?
override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
self.contentHandler = contentHandler
bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)
guard let bestAttemptContent = bestAttemptContent else {
invokeContentHandler(with: request.content)
return
}
do {
let notificationModel = try PushNotificationUserInfo(data: request.content.userInfo)
guard let templatedImageUrl = notificationModel.templatedImageUrlString,
let imageUrl = imageUrl(from: templatedImageUrl) else {
invokeContentHandler(with: bestAttemptContent)
return
}
setupCustomNotificationTask(
imageUrl: imageUrl,
bestAttemptContent: bestAttemptContent,
contentHandler: contentHandler
)
} catch {
invokeContentHandler(with: bestAttemptContent)
}
}
// More code
private func downloadImageTask(
imageUrl: URL,
bestAttemptContent: UNMutableNotificationContent,
contentHandler: @escaping (UNNotificationContent) -> Void
) {
self.customNotificationTask = Task {
let (location, _) = try await URLSession.shared.download(from: imageUrl)
let desiredLocation = URL(fileURLWithPath: "\(location.path)\(imageUrl.lastPathComponent)")
try FileManager.default.moveItem(at: location, to: desiredLocation)
let attachment = try UNNotificationAttachment(identifier: imageUrl.absoluteString, url: desiredLocation, options: nil)
bestAttemptContent.attachments = [attachment]
contentHandler(bestAttemptContent)
}
}
}
I tried using the MainActor.run {}, but it just moved the error to that run function.
The UNNotificationRequest is not sendable, and I don't think I can make it so.
Wrap the setupCustomNotification in a Task will move the errors to the didReceive method.
It seems like the consuming keyword will help here, but it leads to a compilation error, even with the latest Xcode (16.2).
Any pointers?

This strange issue happens after upgrading my iOS to 14.2. On iOS 13, it works normally. We just use regular SKProductRequest to query in-app product then use the price locale to determine the region:
		storeKitProductsRequest = SKProductsRequest(productIdentifiers: productIdentifiers)
and then we get the region like so:
		let task = FetchStoreKitProductsTask(productIdentifier: productIdentifier) { result in
				completion(Result(optionalValue: result.value?.priceLocale.regionCode, errorForNilValue: Error.missingPriceLocaleRegionCode))
		}
Not sure if it's also happening on iOS 14 and 14.1 as well. I'm aware there are several updates on the StoreKit as Apple announced on the WWDC2020. link1 - https://developer.apple.com/videos/play/wwdc2020/10661/ link2 - https://developer.apple.com/videos/play/wwdc2020/10659/
Could it be an iOS bug?
