Swift 3 JSON

iOS 10 ile beraber gelen Swift 3 bazı değişiklere sahip. Swift 2.3 de kullandığımız JSON kodlaması Swift 3.0 convert ettiğimizde hata verecektir.

Bu yazımda size Swift 3.0 JSON veri okumayı anlatacağım.

Aşağıdaki JSON verisini kullanacağız.

KODLAMA :


let requestURL: NSURL = NSURL(string: "http://www.learnswiftonline.com/Samples/subway.json")!
let urlRequest: NSMutableURLRequest = NSMutableURLRequest(url: requestURL as URL)
let session = URLSession.shared
let task = session.dataTask(with: urlRequest as URLRequest) {
(data, response, error) -> Void in

let httpResponse = response as! HTTPURLResponse
let statusCode = httpResponse.statusCode

if (statusCode == 200) {
print(“Everyone is fine, file downloaded successfully.”)

do{

let json = try JSONSerialization.jsonObject(with: data!, options:.allowFragments) as! [String:AnyObject]

if let stations = json[“stations”] as? [[String: AnyObject]] {

for station in stations {

if let name = station[“stationName”] as? String {

if let year = station[“buildYear”] as? String {
print(name,year)
}

}
}

}

}catch {
print(“Error with Json: \(error)”)
}

}
}

task.resume()
