This post updated September 16 for Xcode 6 GM<\/strong><\/i><\/p>\n

Let’s say you’re working on an iOS app where you need to pass data to a server as JSON. Just about every app that interacts with a server does this, and almost always there is a login API call.<\/p>\n

For the purposes of this tutorial, I’m first going to set up a super simple web server that handles a POST request. This part of the tutorial is optional if you already have a server, and you can skip ahead to the Swift code<\/a>. Go ahead and create a ruby file called api.rb, and stick this in there:<\/p>\n

Note: Alternatively, you could use tasty with a Deno web server<\/a> here, which is more similar to Swift than NodeJS.<\/p>\n


\n#!\/usr\/bin\/env ruby
\nrequire 'rubygems'
\nrequire 'sinatra'
\nrequire 'json'
\nget '\/' do
\n\"Nothing to see here. Move along.\"
\nend
\npost '\/login' do
\nvalues = JSON.parse(request.env[\"rack.input\"].read)
\nif values[\"username\"]=='jameson' && values[\"password\"]=='password'
\n\"{\\\"success\\\":1}\"
\nelse
\n\"{\\\"success\\\":0}\"
\nend
\nend
\n<\/code><\/p>\n

Now, I know this is ruby code but it’s just to get us a server up and running fast. To run this you’ll first need to make it executable. Open up a Terminal window and cd to the directory where api.rb is, then you can add the executable permission like this:
\n
\nchmod +x api.rb
\n<\/code><\/p>\n

And you’ll need the gem:<\/p>\n


\ngem install sinatra
\ngem install json
\n<\/code><\/p>\n

Depending on your system’s configuration, this might give you some kind of permissions error. If it does prepend the ‘sudo’ statement in front of this:<\/p>\n


\nsudo gem install sinatra
\nsudo gem install json
\n<\/code><\/p>\n

Note: You normally want ruby gems to be installed in to a user directory using RVM and a gemset, but this is a Swift tutorial so we’re just going to keep moving \ud83d\ude42<\/i><\/p>\n

Okay now give it a whirl:
\n
\n.\/api.rb
\n<\/code><\/p>\n

\n

 
\nYou should now have a web server up and running that accepts a POST call to \/login. The server by default runs on port 4567, so now let’s create a Swift project to interact with it. A simple single-view project is fine for this example.<\/p>\n

In your application didFinishLaunchingWithOptions method add the following:<\/p>\n

func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {\r\n    var request = NSMutableURLRequest(URL: NSURL(string: \"http:\/\/localhost:4567\/login\"))\r\n    var session = NSURLSession.sharedSession()\r\n    request.HTTPMethod = \"POST\"\r\n    \r\n    var params = [\"username\":\"jameson\", \"password\":\"password\"] as Dictionary<String, String>\r\n    \r\n    var err: NSError?\r\n    request.HTTPBody = NSJSONSerialization.dataWithJSONObject(params, options: nil, error: &err)\r\n    request.addValue(\"application\/json\", forHTTPHeaderField: \"Content-Type\")\r\n    request.addValue(\"application\/json\", forHTTPHeaderField: \"Accept\")\r\n    \r\n    var task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in\r\n        println(\"Response: \\(response)\")\r\n        var strData = NSString(data: data, encoding: NSUTF8StringEncoding)\r\n        println(\"Body: \\(strData)\")\r\n        var err: NSError?\r\n        var json = NSJSONSerialization.JSONObjectWithData(data, options: .MutableLeaves, error: &err) as? NSDictionary\r\n        \r\n        \/\/ Did the JSONObjectWithData constructor return an error? If so, log the error to the console\r\n        if(err != nil) {\r\n            println(err!.localizedDescription)\r\n            let jsonStr = NSString(data: data, encoding: NSUTF8StringEncoding)\r\n            println(\"Error could not parse JSON: '\\(jsonStr)'\")\r\n        }\r\n        else {\r\n            \/\/ The JSONObjectWithData constructor didn't return an error. But, we should still\r\n            \/\/ check and make sure that json has a value using optional binding.\r\n            if let parseJSON = json {\r\n                \/\/ Okay, the parsedJSON is here, let's get the value for 'success' out of it\r\n                var success = parseJSON[\"success\"] as? Int\r\n                println(\"Succes: \\(success)\")\r\n            }\r\n            else {\r\n                \/\/ Woa, okay the json object was nil, something went worng. Maybe the server isn't running?\r\n                let jsonStr = NSString(data: data, encoding: NSUTF8StringEncoding)\r\n                println(\"Error could not parse JSON: \\(jsonStr)\")\r\n            }\r\n        }\r\n    })\r\n    \r\n    task.resume()\r\n    return true\r\n}\r\n<\/pre>\n
First we create a request and a session to operate on.
\nNext, we set some params in a Swift dictionary, these values will be passed to the server.<\/p>\n
Using dataWithJSONObject() we can encode our parameters as NSData, and set the HTTPBody of the request to this NSData object.<\/p>\n
Next we add our headers stating we’re working with JSON using addValue()<\/p>\n
Finally we instantiate a NSTask from the NSURLSession object with dataTaskWithRequest()<\/p>\n
The last parameter of dataTaskWithRequest is a closure that contains values for the response, data, or error from our server.<\/p>\n
After deserializing the response with JSONObjectWithData(), we can check json[“success”] for the 0 or 1 coming back from our server to see if the request succeeded, and process the results.<\/p>\n
Most of this is just boilerplate, so it’s useless to move this all out in to a new function, we’ll call it post().<\/p>\n
Move all the post logic out to this method, taking params and url as arguments.<\/p>\n
func post(params : Dictionary<String, String>, url : String) {\r\n    var request = NSMutableURLRequest(URL: NSURL(string: url))\r\n    var session = NSURLSession.sharedSession()\r\n    request.HTTPMethod = \"POST\"\r\n    \r\n    var err: NSError?\r\n    request.HTTPBody = NSJSONSerialization.dataWithJSONObject(params, options: nil, error: &err)\r\n    request.addValue(\"application\/json\", forHTTPHeaderField: \"Content-Type\")\r\n    request.addValue(\"application\/json\", forHTTPHeaderField: \"Accept\")\r\n    \r\n    var task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in\r\n        println(\"Response: \\(response)\")\r\n        var strData = NSString(data: data, encoding: NSUTF8StringEncoding)\r\n        println(\"Body: \\(strData)\")\r\n        var err: NSError?\r\n        var json = NSJSONSerialization.JSONObjectWithData(data, options: .MutableLeaves, error: &err) as? NSDictionary\r\n        \r\n        \/\/ Did the JSONObjectWithData constructor return an error? If so, log the error to the console\r\n        if(err != nil) {\r\n            println(err!.localizedDescription)\r\n            let jsonStr = NSString(data: data, encoding: NSUTF8StringEncoding)\r\n            println(\"Error could not parse JSON: '\\(jsonStr)'\")\r\n        }\r\n        else {\r\n            \/\/ The JSONObjectWithData constructor didn't return an error. But, we should still\r\n            \/\/ check and make sure that json has a value using optional binding.\r\n            if let parseJSON = json {\r\n                \/\/ Okay, the parsedJSON is here, let's get the value for 'success' out of it\r\n                var success = parseJSON[\"success\"] as? Int\r\n                println(\"Succes: \\(success)\")\r\n            }\r\n            else {\r\n                \/\/ Woa, okay the json object was nil, something went worng. Maybe the server isn't running?\r\n                let jsonStr = NSString(data: data, encoding: NSUTF8StringEncoding)\r\n                println(\"Error could not parse JSON: \\(jsonStr)\")\r\n            }\r\n        }\r\n    })\r\n    \r\n    task.resume()\r\n}\r\n<\/pre>\n
Now our main logic can be greatly simplified for making any POST request. Let’s make a couple in the didFinishLaunching method.<\/p>\n
func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {\r\n    \r\n    \/\/ Correct url and username\/password\r\n    self.post([\"username\":\"jameson\", \"password\":\"password\"], url: \"http:\/\/localhost:4567\/login\")\r\n    \r\n    \/\/ Correct url, incorrect password\r\n    self.post([\"username\":\"jameson\", \"password\":\"wrong_password\"], url: \"http:\/\/localhost:4567\/login\")\r\n    \r\n    \/\/ Incorrect url\r\n    self.post([\"username\":\"jameson\", \"password\":\"password\"], url: \"http:\/\/badurl.com\/nonexistent\")\r\n\r\n    return true\r\n}\r\n<\/pre>\n
In your console you should be able to see three login attempts, with only one of them succeeding. This is all great, but we should probably implement a way for the post request to notify our caller of a success or failure. Let’s add a Swift closure as a third method parameter to our post() function, so we can call it upon success or completion.<\/p>\n
func post(params : Dictionary<String, String>, url : String, postCompleted : (succeeded: Bool, msg: String) -> ()) {\r\n<\/pre>\n
Now we have our new postCompleted closure, we can pass back to the caller whether or not the post request “succeeded”, and a string message to display to the user.<\/p>\n
func post(params : Dictionary<String, String>, url : String, postCompleted : (succeeded: Bool, msg: String) -> ()) {\r\n    var request = NSMutableURLRequest(URL: NSURL(string: url))\r\n    var session = NSURLSession.sharedSession()\r\n    request.HTTPMethod = \"POST\"\r\n    \r\n    var err: NSError?\r\n    request.HTTPBody = NSJSONSerialization.dataWithJSONObject(params, options: nil, error: &err)\r\n    request.addValue(\"application\/json\", forHTTPHeaderField: \"Content-Type\")\r\n    request.addValue(\"application\/json\", forHTTPHeaderField: \"Accept\")\r\n    \r\n    var task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in\r\n        println(\"Response: \\(response)\")\r\n        var strData = NSString(data: data, encoding: NSUTF8StringEncoding)\r\n        println(\"Body: \\(strData)\")\r\n        var err: NSError?\r\n        var json = NSJSONSerialization.JSONObjectWithData(data, options: .MutableLeaves, error: &err) as? NSDictionary\r\n        \r\n        var msg = \"No message\"\r\n        \r\n        \/\/ Did the JSONObjectWithData constructor return an error? If so, log the error to the console\r\n        if(err != nil) {\r\n            println(err!.localizedDescription)\r\n            let jsonStr = NSString(data: data, encoding: NSUTF8StringEncoding)\r\n            println(\"Error could not parse JSON: '\\(jsonStr)'\")\r\n            postCompleted(succeeded: false, msg: \"Error\")\r\n        }\r\n        else {\r\n            \/\/ The JSONObjectWithData constructor didn't return an error. But, we should still\r\n            \/\/ check and make sure that json has a value using optional binding.\r\n            if let parseJSON = json {\r\n                \/\/ Okay, the parsedJSON is here, let's get the value for 'success' out of it\r\n                if let success = parseJSON[\"success\"] as? Bool {\r\n                    println(\"Succes: \\(success)\")\r\n                    postCompleted(succeeded: success, msg: \"Logged in.\")\r\n                }\r\n                return\r\n            }\r\n            else {\r\n                \/\/ Woa, okay the json object was nil, something went worng. Maybe the server isn't running?\r\n                let jsonStr = NSString(data: data, encoding: NSUTF8StringEncoding)\r\n                println(\"Error could not parse JSON: \\(jsonStr)\")\r\n                postCompleted(succeeded: false, msg: \"Error\")\r\n            }\r\n        }\r\n    })\r\n    \r\n    task.resume()\r\n}\r\n<\/pre>\n
We’ll also need to modify how we call the method in our applicationDidFinishLaunching function.
\nThe last parameter will now be a closure. Using Swift’s trailing closure syntax we can just end the post call with the block { }
\nInside of this closure we create an UIAlertView control and populate it based on the succeeded and msg variables.
\nThen, we move back to a foreground thread and show the alert view.<\/p>\n
func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {\r\n    \r\n    \/\/ Correct url and username\/password\r\n    self.post([\"username\":\"jameson\", \"password\":\"password\"], url: \"http:\/\/localhost:4567\/login\") { (succeeded: Bool, msg: String) -> () in\r\n        var alert = UIAlertView(title: \"Success!\", message: msg, delegate: nil, cancelButtonTitle: \"Okay.\")\r\n        if(succeeded) {\r\n            alert.title = \"Success!\"\r\n            alert.message = msg\r\n        }\r\n        else {\r\n            alert.title = \"Failed : (\"\r\n            alert.message = msg\r\n        }\r\n        \r\n        \/\/ Move to the UI thread\r\n        dispatch_async(dispatch_get_main_queue(), { () -> Void in\r\n            \/\/ Show the alert\r\n            alert.show()\r\n        })\r\n    }\r\n\r\n    return true\r\n}\r\n<\/pre>\n
Give it a whirl, and can now see a server logging in a user (or failing to) with some UI feedback. Cool right?<\/p>\n
Try changing the login information and see what you get.<\/p>\n
This is an overly simplistic server but I just wanted to demonstrate how you would go about making a POST request in Swift. I hope it was helpful!<\/p>\n
