http request with consumer key in swift 3.0 - swift

Question

I am really new to Swift and I'm trying to make a http request to a URL with consumer key and consumer secret and honestly I'm not sure that is even possible to do in Swift.
I've been trying to make this work with authentication method but it only gives me an error.
My code (Hope this helps you to understand what I'm trying to do..)
let baseUrl = "my url"
let consumer_key = "consumer_key"
let consumer_secret = "consumer_secret"
let loginString = NSString(format:"%#:%#", consumer_key, consumer_secret)
let loginData = loginString.data(using: String.Encoding.utf8.rawValue)!
let base64LoginString = loginData.base64EncodedString()
let url = URL(string: baseUrl)
var request = URLRequest(url: url!)
request.httpMethod = "GET"
request.setValue("Basic \(base64LoginString)", forHTTPHeaderField: "Authorization")
let config = URLSessionConfiguration.default
let authString = "Basic \(base64LoginString)"
config.httpAdditionalHeaders = ["Authorization" : authString]
let session = URLSession(configuration: config)
session.dataTask(with: url!) {
(data, response, error) in
if (response as? HTTPURLResponse) != nil {
print("in session")
let dataString = NSString(data: data!, encoding: String.Encoding.utf8.rawValue)
print("data please...",dataString!)
}
}.resume()
If this http call with consumer key and consumer secret is totally unacceptable in Swift or if there is any other way that I can get by this, please let me know.
Thank you in advanced.

Answer 1

Based on your response, it looks as if you are running into ATS issues - the network code does not run at all since the URL is an http:// URL and not an https:// one.
If you have a secure URL with https:// I would suggest you use it. Otherwise, you can add an ATS exception as detailed in the following SO thread:
Transport security has blocked a cleartext HTTP

Answer 2

I figured this out by changing my URLsession function.
session.dataTask(with: url!, completionHandler: {
(data, response, error) in
if (error != nil) {
print("in session error", error.debugDescription)
} else {
do {
print("in session")
self.orderData = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as! NSDictionary
OperationQueue.main.addOperation {
self.orderView.reloadData()
print("data", self.orderData)
}
} catch let error as NSError {
print(error)
}
}
}).resume()
Now I see "in session" in my console which means it making http call properly but I'm facing a new problem which it says Cannot assign value of type 'NSDictionary' to type '[[String: AnyObect]]'. But I'm still happy that my http call works and finally I can start banging my head to a different problem.
Thank you all for helping and I hope this answer can help others as well.
