How to cancel `request.Cancel()` During `appWillterminate` in AlamoFire?

Question

I am trying to save the downloaded data in download failure case

            switch response.result{
        case .success( _):
            print("success response")
            break
        case .failure( _):
            print("error")
            if let resumeData = response.resumeData{
                self.resumeData = resumeData
                Shared.dataCache.set(value: resumeData, key: self.keyResumeData)
            }
        }

When I trigger request.Cancel() using button press event its working perfectly. But when I trigger the same function during appWillTerminate its not getting into failure case. Is there any way to save downloaded data during App Termination using Alamofire

I think this may work for you:

 URLSession.shared.getAllTasks(){
            tasks in
            tasks.forEach { $0.cancel() }
        }
