I am new to Swift 4
and working on an iOS app
. I have the following JSON
data retrieved from the server
which will be extracted to data table
.
[
{
"fund_nav_validity":"24 August to 31 August 2016\n",
"fund_nav_cost":10,
"fund_nav_sell":9.85,
"nav_id":118,
"fund_nav_buy":10,
"fund_id":1,
"nav_as_on_date":"24-Aug-16",
"fund_nav_market":9.95
},
{
"fund_nav_validity":"04 September to 07 September 2016\n",
"fund_nav_cost":10,
"fund_nav_sell":9.85,
"nav_id":117,
"fund_nav_buy":10,
"fund_id":1,
"nav_as_on_date":"01-Sep-16",
"fund_nav_market":9.95
}
]
I have done following task in the navdata function to retrieve the '__NSIArrayI' to JSON:
func getNAVData(){
Alamofire.request(url, method: .post).responseJSON{
response in
if response.result.isSuccess{
print("Success")
//let navDataJSON : JSON = JSON(response.result.value!
let navDataJSON : JSON = JSON(response.result.value!)
print(navDataJSON)
}else{
print("Failed")
}
}
}
I need to convert it to JSON Array
which is done in java
. How to do the similar task in Swift 4
?
you are in the right way, in here you need to convert your JSON response to array the reason your json started with this type[{}] and check your JSON response contains the value or not in intially. try the below code
if response.result.isSuccess{
print("Success")
// convert your JSON to swiftyJSON array type if your JSON response as array as well as check its contains data or not
guard let resJson = JSON(responseObject.result.value!).array , !resJson.isEmpty else { return
}
// create the Swifty JSON array for global access like wise
var navDataJSON = [JSON]() //[JSON]() --> Swifty-JSON array memory allocation.
navDataJSON = resJson
}
