How to check specific value in JSONArray? - json

Question

I have a little problem with looping in Swift 3. I have one JSONArray and one JSONObject like below :
dataReqList [Any] :
[{
bezeich = "MORE SALT";
grpnr = 0;
nr = 1;
}, {
bezeich = "MORE SWEET";
grpnr = 0;
nr = 2;
}, {
bezeich = "MORE PEPPER";
grpnr = 0;
nr = 3;
}, {
bezeich = "MORE CHILLI";
grpnr = 0;
nr = 4;
}, {
bezeich = COLD;
grpnr = 0;
nr = 5;
}, {
bezeich = HOT;
grpnr = 0;
nr = 6;
}, {
bezeich = SMALL;
grpnr = 0;
nr = 7;
}, {
bezeich = LARGE;
grpnr = 0;
nr = 8;
}, {
bezeich = "MEDIUM COOKED";
grpnr = 0;
nr = 9;
}, {
bezeich = "WELL DONE";
grpnr = 0;
nr = 10;
}]
currArticle [Anyhashable: Any] :
Optional([AnyHashable("bezeich"): Fresh and Green Salad,
AnyHashable("special-request"): ["MORE PEPPER", "COLD", "HOT"]])
I want to know, how to print the key bezeich in array , if the JSONArray have same String with special-request in JSONObject. I've try this but its not working :
for i in 0..<dataReqList.count {
if ( ((dataReqList[i] as? [AnyHashable: Any])? ["bezeich"] as! String) == (("\(currArticle?["special-request"]!)") as String) ) {
print (dataReqList[i])
}
Any answer and suggest will help for me. Thanks in advance
EDIT :
I'm new in Swift. I have read THIS before but its still not work.

Key special-request with currArticle Dictionary having Array of String as value so you can not directly compare it with string, you can use filter for that like this.
var filterArray = [[String:Any]]()
if let dataArray = dataReqList as? [[String:Any]],
let specialRequestArray = currArticle["special-request"] as? [String] {
filterArray = dataArray.filter { specialRequestArray.contains($0["bezeich"] as? String ?? "") }
print(filterArray)
}
