Any nicer way than this???

// Case 1:
let indexText = atIndex != nil ? "-\(atIndex!)" : ""

// Case 2:
let myArray = someObject != nil ? [someObject!] : []

// Longer solution
var myArray = []
if let obj = someObject {
   myArray = [obj]
}

// Other similar cases :)
let myPrice: GraphQL.PriceInput? = price != nil ? GraphQL.PriceInput(amount: price!.amount, currency: price!.currency) : nil
// ------------------------------------
let width = ad.width != nil ? R.string.localizable.ad_details_attr_measurement_centimetres(Double(ad.width!)) : nil
// ------------------------------------
return intValue != nil ? String(intValue!) : nil
