Answer 1

I have created a sample to read json file placed in your project. and have integrated the code as per your requirement.
Json File
{"Status":"success","Data":[
{"activeFromDate":"01/01/2017","terminateDate":"02/05/2019"},
{"activeFromDate":"01/01/2013","terminateDate":null},
{"activeFromDate":"01/01/2017","terminateDate":"02/05/2018"},
{"activeFromDate":"07/01/2012","terminateDate":null},
{"activeFromDate":"01/01/2017","terminateDate":"02/05/2016"},
{"activeFromDate":"01/01/2017","terminateDate":"02/05/2019"}
]
}
In your View Controller
import UIKit
class HomeViewController: UIViewController {
let answerArray = NSMutableArray()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
jsonParsingFromFile()
}
func jsonParsingFromFile()
{
let path: NSString = Bundle.main.path(forResource: "tjw", ofType: "json")! as NSString
let data : NSData = try! NSData(contentsOfFile: path as String, options: NSData.ReadingOptions.dataReadingMapped)
self.startParsing(data: data)
}
func startParsing(data :NSData)
{
let dict: NSDictionary!=(try! JSONSerialization.jsonObject(with: data as Data, options: JSONSerialization.ReadingOptions.mutableContainers)) as? NSDictionary
//print(dict)
guard let dataArr:NSArray = dict.value(forKey: "Data") as? NSArray else {
return
}
print(dataArr.count)
for i in 0..<dataArr.count{
guard let currentDict:NSDictionary = dataArr[i] as? NSDictionary else {
return
}
let activeFromDateStr:String = currentDict.value(forKey: "activeFromDate") as? String ?? ""
let terminateDateStr:String = currentDict.value(forKey: "terminateDate") as? String ?? ""
print(activeFromDateStr, terminateDateStr)
if terminateDateStr != ""{
let date2 = convertToDate(dateStr: terminateDateStr)
let today = Date()
if date2>today{
answerArray.add(currentDict)
}
}else{
answerArray.add(currentDict)
}
}
print(answerArray)
}
func convertToDate(dateStr:String)->Date{
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd/MM/yyyy"
dateFormatter.locale = Locale(identifier: "en_IN")
let date = dateFormatter.date(from: dateStr)!
return date
}
}
