###Basic: Download a file in the Digger directory under the sandbox's Caches

   Digger.download(url)

Choose different callbacks depending on your needs

        
  Digger.download(url)
        .progress(nil)
        .speed(nil)
        .completion(nil)

   let url = "http://example.com/digger.mp4"

        Digger.download(url)
            .progress({ (progresss) in
                print(progresss.fractionCompleted)

            })
            .speed({ (speed) in
                print(speed)
            })
            .completion { (result) in
                
                switch result {
                case .success(let url):
                    print(url)
                    
                case .failure(let error):
                    print(error)
                    
                }
                
        }
}

Config yourself

/// Start the task at once,default is true

DiggerManager.shared.startDownloadImmediately = false

/// maxConcurrentTasksCount,deault is 3

DiggerManager.shared.maxConcurrentTasksCount = 4

///  request timeout,deault is 100 

DiggerManager.shared.timeout = 150

/// allowsCellularAccess,deault is true

DiggerManager.shared.allowsCellularAccess = false

/// loglevel,deault is high
/*

file   : ExampleController.swift

*/
// If you want to close,set the level to be .none

DiggerManager.shared.logLevel = .none




// MARK:-  DiggerCache

/// In the sandbox cactes directory, custom your cache directory

DiggerCache.cachesDirectory = "Directory"

/// Delete all downloaded files

DiggerCache.cleanDownloadFiles()

/// Delete all temporary download files

DiggerCache.cleanDownloadTempFiles()

/// Get the system's available memory size

_ = DiggerCache.systemFreeSize()

/// Get the size of the downloaded file
