Searchbar filter based on json - ios

Question

I'm having a name value to my tableviewcell like so..
for asd in orderDetails {
if let jsonStr = asd.value(forKey: "customerJson") as? String {
let data = jsonStr?.data(using: String.Encoding.utf8, allowLossyConversion: false)!
do {
if let json = try JSONSerialization.jsonObject(with: data!) as? [String: Any] {
for item in json {
if item.key == "first_Name" {
cell.nameLabel.text = item.value as? String //ASSIGNED HERE
}
}
}
} catch let error as NSError {
print("Failed to load: \(error.localizedDescription)")
}
}
}
Now I want to search on the search bar based on this name. While searching in other cases where the core data attributes were mentioned directly I did something like so which worked fine..
filtered = self.newProdDetails.filter({( data : NewProduct) -> Bool in
return (data.name?.lowercased().contains(searchText.lowercased()))! //Here the entity NewProduct has an attribute name
})
But in the current scenario, the attribute is a json string called customer_json given like so and I wanted to filter based on the first_name..
customer_json={
"mobile_number”:”9876543210”,
"first_name”:”testName”,
"last_name”:”testLastName”,
"seller_id":"93"
}

simply parse your JSON into the array or dictionary a/c to json with help :
let arrayJson = JSONSerialization.jsonObject(with:....
.....
then apply Search simply on an array like this :
let filterArr = arrayJson.filter {
return (($0["first_name"] as! String).lowercased().contains(searchText.lowercased()))
}
