A long time since I have written iOS code but I have the following Model in an iOS app and works great but now we are finding out that detail is optional and we should allow nil values. How would I adjust the initializer to support this? Sorry, I find the optionals a bit difficult to grasp (concept makes sense - executing it is difficult).
class Item{
var id:Int
var header:String
var detail:String
init?(dictionary: [String: AnyObject]) {
guard let id = dictionary["id"] as? Int,
let header = dictionary["header"] as? String,
let detail = dictionary["detail"] as? String else {
return nil
}
self.id = id
self.header = header
self.detail = detail
}
and creating:
var items = [Item]()
if let item = Item(dictionary: dictionary) {
self.items.append(item)
}
