 NSData* data = [response.data dataUsingEncoding:NSUTF8StringEncoding];
 NSDictionary *dictResponse = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];

 NSString *authUsername = [NSString stringWithFormat: @"%@ %@", [dictResponse valueForKey: @"firstName"], [dictResponse valueForKey: @"lastName"]];

This is how I managed to authenticate a user via LinkedIn, using SwiftyJSON library to parse the response. https://github.com/SwiftyJSON/SwiftyJSON As of May 2015 LinkedIn limited access to their API allowing only basic profile fields/email to be accessed. You also need to set the basic permissions for r_basicprofile and r_emailaddress under your app in the developer console in order for this to work.

Hope this helps

@IBAction func connectWithLinkedIn(sender: AnyObject) {

  let url = NSString(string:"https://api.linkedin.com/v1/people/~:(id,industry,firstName,lastName,emailAddress,headline,summary,publicProfileUrl,specialties,positions:(id,title,summary,start-date,end-date,is-current,company:(id,name,type,size,industry,ticker)),pictureUrls::(original),location:(name))?format=json")

    let permissions: [AnyObject] = [LISDK_BASIC_PROFILE_PERMISSION, LISDK_EMAILADDRESS_PERMISSION]

    LISDKSessionManager.createSessionWithAuth(permissions, state: nil, showGoToAppStoreDialog: true, successBlock: { (success) -> () in
        if LISDKSessionManager.hasValidSession() {
            LISDKAPIHelper.sharedInstance().getRequest(url as String, success: {
                response in
                print(response)
                print("successfully signed in")

                dispatch_async(dispatch_get_main_queue(), { () -> () in

                    if let dataFromString = response.data.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false) {
                        let result = JSON(data: dataFromString)


                        LISDKSessionManager.clearSession()

                        //Do something with the response for example
                        var picURL: String!

                        for stringInArray in result["pictureUrls"]["values"]{

                            let value = stringInArray.1.stringValue
                            print(value)
                            picURL = value
                        }
                       print(result["pictureUrls"]["values"].arrayValue)
                       print(result["specialties"].stringValue)


                        }


                })

                }, error: {
                    error in

                    LISDKAPIHelper.sharedInstance().cancelCalls()
                    LISDKSessionManager.clearSession()

                    print(error.localizedDescription)
                    //Do something with the error
            })
        }


        print("success called!")


        }, errorBlock: { (error) -> () in
            print("%s", "error called!")

            LISDKAPIHelper.sharedInstance().cancelCalls()
            LISDKSessionManager.clearSession()
    })




}

You can prefer this snippet for LinkedIn sharing:

Paste it into the valid session condition LISDKSessionManager.hasValidSession()

Swift 3x :

let url: String = "https://api.linkedin.com/v1/people/~/shares"

let payloadStr: String = "{\"comment\":\"YOUR_APP_LINK_OR_WHATEVER_YOU_WANT_TO_SHARE\",\"visibility\":{\"code\":\"anyone\"}}"

let payloadData = payloadStr.data(using: String.Encoding.utf8)


LISDKAPIHelper.sharedInstance().postRequest(url, body: payloadData, success: { (response) in

print(response!.data)

}, error: { (error) in

print(error as! Error)

let alert = UIAlertController(title: "Alert!", message: "aomething went wrong", preferredStyle: .alert)
let action = UIAlertAction(title: "OK", style: .default, handler: nil)

alert.addAction(action)
self.present(alert, animated: true, completion: nil)


})
