How to cancel all requests in Alamofire's shared manager

Question

How to cancel all requests in Alamofire's shared manager?

This is my function:

class func cancelAllRequests() {
    Alamofire.Manager.sharedInstance.session.getTasksWithCompletionHandler { (dataTasks, uploadTasks, downloadTasks) in
        self.each(dataTasks, function: self.cancel)
        self.each(uploadTasks, function: self.cancel)
        self.each(downloadTasks, function: self.cancel)
    }
}

class func cancel(index: Int, element: AnyObject) {
    if let task = element as? NSURLSessionTask {
        task.cancel()
    }
}

class func each<T>(array: [T], function: (Int, T) -> ()) {
    for (index, t) in enumerate(array) {
        function(index, array[index])
    }
}

Can it works?

Use NSURLSession's invalidateAndCancel method:

manager.session.invalidateAndCancel

Sorry, I don't think it works. In the API document, it says " finishTasksAndInvalidate and invalidateAndCancel do not have any effect on the shared session singleton." – Eric Chen Dec 16 '14 at 04:45
OK, so create your own manager that instantiates a new session. – mattt Dec 16 '14 at 19:12

This is for Swift 4.0 and Alamofire Version 4.5

Alamofire.SessionManager.default.session.getAllTasks{ $0.forEach{ $0.cancel() } }

For Alamofire version 5.0+, SessionManager has been replaced by Session. Just use

Session.default.cancelAllRequests()

to cancel all currently running requests created by AF.request().
