If you don't know where in the Apple Docs to begin take a look here: https://www.raywenderlich.com/11395893-push-notifications-tutorial-getting-started

if this is hybrid you'll have to follow up with the javascript framework creators seeing there is no visible objective-c or swift stack trace associated with what looks like controller which is not native - 'box.medusa.bbammsimagesearchviewcontroller1229'.

Take a look at the most recent set of framework APIs added, this could be an API only available to iOS 15 and higher.

Wrong forum, you're looking for: https://discussions.apple.com/community/iphone

Maybe for the destructor call instead of using an if probably a while testing the function below. func CFRunLoopContainsObserver(_ rl: CFRunLoop!, _ observer: CFRunLoopObserver!, _ mode: CFRunLoopMode!) -> Bool https://developer.apple.com/documentation/corefoundation/1542815-cfrunloopcontainsobserver

This question is better suited for the consumer support forum http://support.apple.com/

Try wrapping any C++ methods with Objective-C methods then only expose the Objective-C methods to Swift with a new Swift name. https://developer.apple.com/documentation/swift/objective-c_and_c_code_customization

Just means you have to do some debugging, root cause analysis looking for removed or deprecated APIs, read the release notes to find out what changes might have affected your code based or even try the new Xcode 13.2 from more downloads, upgrade macOS 12.1 and code defensively for old and any new APIs.

Why not just use async/await? I'm not sure why you're moving the http session time out 30 seconds to 7 seconds. It doesn't make the request any faster just creates problems if the call takes more than 7 seconds to complete. func fetchData(from url: URL) async throws -> [DataModel] { let session = URLSession.shared let (data, _) = try await session.data(from: url) let decoder = JSONDecoder() decoder.keyDecodingStratergy = .converFromSnakeCase // <-- depends on JSON you might not need it return try decoder.decode([DataModel].self, from: data) } View Controller Task { let dataModel = try? await viewModel.fetchData(from: URL(string:"https://api.github.com/repos/ReactiveX/RxSwift/events")!) DispatchQueue.main.async { // give the data model to some other API on the main thread } }

Do have the latest Xcode 13.2.1?

The documentation above has been archived but this is a detail we should not worry about but one can assume the structures are the same.

For some with a prior version installed update deltas can be as small as 400 MB but have the same perception of being stuck. Eventually, it finishes but can assume the update duration has something to do with patching an already codesigned toolset with a foreign set of binaries that most likely will take on the new code signatures. Who knows, maybe Apple can provide information in the UI/UX when the process is either downloading or installing or patching, I'm just postulating!
