Alamofire json parsing - ios

Question

self.manager!.request( url+"FindNearestClasses", method: .post, parameters: requestDictionary, encoding: URLEncoding.httpBody,headers: headers
).responseJSON { response in
print(response.result.value)
}
The problem I have the json returned to me is like below. How can I parse it by number that is get array, and then after array each read first second third and fourth numbers.
[
[
"1",
"2",
"3",
4],
[
"5",
"6",
"7",
8]
]

Answer 1

let myjson = [ [ "1", "2", "3", "4"], [ "5", "6", "7", "8"] ]
let myInt = Int(myjson[0].first as! String)
/*
let i = 0
let j = 0
let myInt = Int(myjson[i][j] as! String)
i stands for the which array 0 or 1 in this case. j stands for the value inside that array.
*/
print(myInt)
This will print 1 as Int, if you want to loop through entire array then use for loop.
for myi in myjson{
for myj in myi {
print(myj) // this will print all the contents of both array.
}
}
To convert string to Int, use _ = Int(myjson[i][j] as! String)

The best way is to use a tool to map the response into swift objects, an example is Object mapper: https://github.com/tristanhimmelman/AlamofireObjectMapper
import AlamofireObjectMapper
let URL = "https://raw.githubusercontent.com/tristanhimmelman/AlamofireObjectMapper/d8bb95982be8a11a2308e779bb9a9707ebe42ede/sample_json"
Alamofire.request(URL).responseObject { (response: DataResponse<WeatherResponse>) in
let weatherResponse = response.result.value
print(weatherResponse?.location)
if let threeDayForecast = weatherResponse?.threeDayForecast {
for forecast in threeDayForecast {
print(forecast.day)
print(forecast.temperature)
}
}
}
