Search string in array

Question

I have this code:

[
  {
    "id": 176,
    "aSegments": [
      "CUT_SPECIALITIES1", 
      "CUT_SPECIALITIES2", 
      "CUT_SPECIALITIE2S"
    ],
    "sunFl": true,
    "inPi": false,
    "noBox": 72,
    "prepOven": "15 min / 220C"
  }
]

let searchString = "CUT_SPECIALITIES2"
let products = DataMgr.instance.getProducts(reload: false)
var productsObjectArray = products.filter({
   return  (($0.aSegments?.filter({
       $0.description.lowercased().contains(searchString.lowercased())
   }))?.count)! > 0
})

How can I search CUT_SPECIALITIES2 to find the searched string?

Try to format you question, please. It's really hard to read the spaghetti in last line :( — pacification

This is the array I assumed you have :

let array = [
[
    "id" : 176,
    "aSegments": [
    "CUT_SPECIALITIES1",
    "CUT_SPECIALITIES2",
    "CUT_SPECIALITIE2S"
    ],
    "sunFl": true,
    "inPi": false,
    "noBox": 72,
    "prepOven": "15 min / 220C"
    ],
[
    "id" : 177,
    "aSegments": [
        "CUT_SPECIALITIES1",
        "CUT_SPECIALITIES2",
        "CUT_SPECIALITIE2S"
    ],
    "sunFl": true,
    "inPi": false,
    "noBox": 73,
    "prepOven": "18 min / 120C"
    ]
]

And from this Array of Dictionaries, you want to filter the dictionaries based on the searchString.

let searchString = "CUT_SPECIALITIES2"
let filteredArray = array.filter { (singleProduct) -> Bool in
    guard let aSegments = singleProduct["aSegments"] as? [String] else {
       return false
    }
    return (aSegments.filter({ $0 == searchString }).count > 0)
}

This gives an Array of Dictionaries which contains your searched string.
