I have above json. what i want is to use filter to get skudetails of object for only those whose color is gold and storage is 64 gb. can it be achievable through filter? As for first level filtering its working fine for me like this :
if let skuDetailArray = self.deviceSKUsAndDetailsResponse?.skuDetails
let demandId = skuDetailArray.first(where: { $0.demandId == "3060416" })
but i could not able to parse data for above conditions, and if its not possible through than can it be possible through predicate, or any other method than please let me know.
**

let displayText : String?
let key : String?
let value : String?
}

Answer 1

The following code will return any SWSkuDetail that has the Color = Gold and Storage = 64 GB.
The filter function first filters out the elements with the given keys and then check that it has gotten 2 hits and that both values exists in those two.
let keyColor = "Colour"
let keyStorage = "Storage"
let filtered = skuDetailArray.filter { detail in
guard let props = detail.skuCoreProperties else { return false }
let array = props.filter { $0.key == keyColor || $0.key == keyStorage }.map {$0.value}
return array.count == 2 && array.contains("Gold") && array.contains("64GB")
}
