Optionals in Swift - not assigning default value for optionals

Question

let company : String? // = nil

if company == nil {
   var newCompany = company ?? "apple"
}

In this code identifier company we need to assign as let company : String? = nil but apple documentation is telling that no need for assigning nil value

`let company: String? = Optional.none print(company == nil) //true` — Salman Ghumsani, Oct 06 '17 at 12:16

You declared a constant without a value and without an initializer that can change it, which is nonsensical. The compiler, therefore, warns you that you should initialize the constant.

Change let to var and your code will work fine.
