How to search an element in Array of Dictionary?

Below mentioned is my array. I need to check if the barcode 8901058847857 or barcode xxxxxxxxxxx exists in array or not. 

    (
        {
        barcode = 8901058847857;
        image =         (
        );
        name = "Maggi Hot Heads";
        productTotal = "60.00";
        quantity = 3;
    },
        {
        barcode = 8901491101837;
        image =         (
        );
        name = "Lays Classic Salted";
        productTotal = "20.00";
        quantity = 1;
    }
)

I tried using array.contains or array.elements but it is not working because barcode exists in an array.

You can also run for loop to check the presence of element in your Array of dictionary.

let DictnaryArray =     (
        {
        barcode = 8901058847857;
        image =         (
        );
        name = "Maggi Hot Heads";
        productTotal = "60.00";
        quantity = 3;
    },
        {
        barcode = 8901491101837;
        image =         (
        );
        name = "Lays Classic Salted";
        productTotal = "20.00";
        quantity = 1;
    }
)

for (index,element) in DictnaryArray{

let dict = DictnaryArray[index]

   if dict["barcode"] == 8901058847857 || dict["barcode"] == XXXXXXXXXXX{
     print("BarCode Exist")
     print("\(dict["barcode"])")
   }
}

Hope it helps!

** Try this ** 

 // Put your key in predicate that is "barcode"

var namePredicate = NSPredicate(format: "barcode contains[c] %@",searchString);

let filteredArray = arrayOfDict.filter { namePredicate.evaluate(with: $0) };

print("names = ,\(filteredArray)")

You can search your array of dictionaries using contains where but you need to cast your value from Any to Int before trying to compare them:

if array.contains(where: {$0["barcode"] as? Int ?? 0 == 8901058847857}) { 
    print(true)
}
