swift: Alphabetiz data being parsed from a JSON - ios

Question

I wrote my own function in Swift2 to parse a JSON. Once the JSON is parsed, a list of data that was pulled from the JSON is displayed in a tableView on my app. I am trying to figure out how to display this data in alphabetical order. I think this needs to happen somewhere before the append method I call in the function. I would imagine this needs to be a sort function but I have not been able to figure out the correct sort function in Swift2 that will execute this properly. Any help I can get is appreciated!
Here is my parseJSON function:
func parseJSON(){
do{
let data = NSData(contentsOfURL: NSURL(string: "https://jsonblob.com/api/jsonBlob/580d0ccce4b0bcac9f837fbe")!)
let jsonResult = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers)
for anItem in jsonResult as! [Dictionary<String, AnyObject>]{
let mifiName2 = anItem["name"] as! String
let mifiId = anItem["employeeId"] as! Int
let newName = Name(mifiName: mifiName2, mifiId: mifiId)
nameOfMifi.append(newName)
//print("Name: \(newName)")
}
}
catch let error as NSError{
print(error.debugDescription)
}
}

You need to sort your array after all the object is append in Array means after the for loop.
for anItem in jsonResult as! [Dictionary<String, AnyObject>]{
let mifiName2 = anItem["name"] as! String
let mifiId = anItem["employeeId"] as! Int
let newName = Name(mifiName: mifiName2, mifiId: mifiId)
nameOfMifi.append(newName)
//print("Name: \(newName)")
}
//Now you need to sort your array on the basis of name like this
nameOfMifi.sortInPlace { $0.mifiName < $1.mifiName }
Edit: As #vadian suggested do not use NSData(contentsOfURL:) because it will block your UI, so batter to use NSURLSession like this.
let session = NSURLSession.sharedSession()
let url = NSURL(string: "https://jsonblob.com/api/jsonBlob/580d0ccce4b0bcac9f837fbe")!
var task = session.dataTaskWithURL(url, completionHandler: {
(data, response, error) -> Void in
if error != nil {
return
}
if let jsonResult = try? NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers) as? [Dictionary<String, AnyObject>] {
for anItem in jsonResult {
let mifiName2 = anItem["name"] as! String
let mifiId = anItem["employeeId"] as! Int
let newName = Name(mifiName: mifiName2, mifiId: mifiId)
nameOfMifi.append(newName)
//print("Name: \(newName)")
}
//Now you need to sort your array on the basis of name like this
nameOfMifi.sortInPlace { $0.mifiName < $1.mifiName }
//Now reload tableView on main thread.
dispatch_async(dispatch_get_main_queue()) {
self.tableView.reloadData()
}
}
})
task.resume()
