Check network connection and speed with a single method call. connectedness first checks your access to the network (wifi or mobile 1X/3G/LTE), then determines your network's speed by loading a dummy resource.

It checks this network speed with a default timeout of 5 seconds, then compares your speed to the approximate national average 3G network - if it is slower than this average, an error is thrown for you to handle as you please.

• Xcode 7 or higher
• iOS 8.0 or higher
• Swift 2.3

Add the connectedness.swift file into your project.

1.) Determine Resource

Replace the link in the testDownloadSpeedWithTimout...() function with a link to your own resource. A random .txt file will do.

public func testDownloadSpeedWithTimout(timeout: NSTimeInterval, completionHandler:(megabytesPerSecond: Double?, error: NSError?) -> ()) {
        let url = NSURL(string: "https://insert.your.site.here/yourfile")!
...

2.) Determine what you want your network speed to be compared against by changing the value associated with the if megabytesPerSecond!>= ... {. Also, change the number associated with testDownloadSpeedWithTimout(...) to increase or decrease the timeout time, in seconds. See below.

connectedSpeed().testDownloadSpeedWithTimout(5.0) { (megabytesPerSecond, error) -> () in
        if ((error == nil) && isReachable && !needsConnection){
            if megabytesPerSecond!>=0.05{
 ...

The default 0.05 measures out approximately to the national average 3G network. Lower this number to compare against slower speeds, and raise it to compare against higher speeds. This is most useful when you may want to tell users that their slow speed will negatively affect their user experience and tell them to try for a better signal.

For example, a value of 1.1 equates to a wifi connection speed of around 35 Mbps. These numbers are not exact.

3.) Simply call the connectedToNetwork() from anywhere in your project. Connection will be determined first, then speed will be measured.

func viewDidLoad(){
  connectedToNetwork()
}

Debugger prints your connectivity nicely
