Swift dictionary retrieve values - swift

Question

Hello I am using the linked in SDK to log into my app.
The API returns a json string which i have converted to a dictionary object.
Using the line below I can successfully retrieve some of the values.
let firstName : NSString? = dict?["firstName"] as? NSString
How would I retrieve the company name and the job title?
["publicProfileUrl": https://www.linkedin.com/in/joebloggs, "formattedName": Joe Bloggs, "id": Zazobgtf1Q, "pictureUrls": {
"_total" = 1;
values = (
"https://media.licdn.com/mpr/mprx/0_xBXVf6v56zJf42DuUQJy70N69gfspmi8VYJMYZq_Q6X8SCm_a-4jUmz6FF4wOai_xjJMpPN_qiNQ7xaiUpvv4jq5_iN67xx8apv4S6HL9JLf7HadaZ5JIuNzlJ"
);
}, "pictureUrl": https://media.licdn.com/mpr/mprx/0_OzOPtLSS9GH8gFDYUA6-xtfSKPkgY5YmNkEPBAGSc5ypRvS_AzXjVcuSNssssXO_qkE1Mi_DxXcyZT2mBQR7sAa3VXcjZTdGlQRKlrR2ALGltB-YjcSOAkzjslDDATY14Lxx9mjGA2G, "lastName": Bloggs, "emailAddress": joe#gmail.com, "positions": {
"_total" = 1;
values = (
{
company = {
id = 9433004;
industry = "Marketing & Advertising";
name = "Company Name";
size = "2-10";
type = "Privately Held";
};
id = 865817330;
isCurrent = 1;
location = {
country = {
code = gb;
name = "United Kingdom";
};
name = "Leeds, United Kingdom";
};
startDate = {
month = 9;
year = 2016;
};
title = "Staff";
}
);
}, "firstName": Joe]
Here is the code I am using for the linkedIn login:
func linkedInLogin(){
LISDKSessionManager.createSession(withAuth: [LISDK_BASIC_PROFILE_PERMISSION, LISDK_EMAILADDRESS_PERMISSION], state: nil, showGoToAppStoreDialog: true, successBlock: { (returnState) -> Void in
print("success called!")
let session = LISDKSessionManager.sharedInstance().session
//let url = "https://api.linkedin.com/v1/people/~"
let url = "https://api.linkedin.com/v1/people/~:(id,summary,positions,email-address,first-name,last-name,public-profile-url,formatted-name,picture-url,picture-urls::(original))?format=json"
if LISDKSessionManager.hasValidSession() {
LISDKAPIHelper.sharedInstance().getRequest(url, success: { (response) -> Void in
// print(response!.data!)
let str = response!.data!
let dict = self.convertToDictionary(text: str)
print(dict!)
let firstName : NSString? = dict?["firstName"] as? NSString
let lastName : NSString? = dict?["lastName"] as? NSString
let email : NSString? = dict?["emailAddress"] as? NSString
let userName : NSString? = dict?["formattedName"] as? NSString
let linkedInID : NSString? = dict?["id"] as? NSString
let link : NSString? = dict?["publicProfileUrl"] as? NSString
let liid : NSString? = dict?["id"] as? NSString
let picurl : NSString? = dict?["pictureUrl"] as? NSString
// let summary : NSString? = dict?["summary"] as? NSString
let positions : NSString? = dict?["positions"] as? NSString
}, error: { (error) -> Void in
print(error!)
})
}
}) { (error) -> Void in
print("Error: \(error)")
}
}
func convertToDictionary(text: String) -> [String: Any]? {
if let data = text.data(using: .utf8) {
do {
return try JSONSerialization.jsonObject(with: data, options: []) as? [String: Any]
} catch {
print(error.localizedDescription)
}
}
return nil
}
