'fromPost' not found in type 'Destiny?' in Travis, but the type is declared in base file

I use public to declare type of Enum, I understand its the common base class of all Java language enumeration types.

public enum Destiny {
    case fromTrail
    case fromPost

And use in another part of code, like that:

 convenience init(withDestinySearch from: Destiny) {
        self.init(collectionViewLayout: UICollectionViewFlowLayout())
        destinySearch = from

Works locally I may add.
App/Features/Search/Controller/SearchController.swift:91:19: enum case ‘fromPost’ not found in type ‘Destiny’

Well, the problem is that destinySearch is an optional so the value theoretically is nil, unless you’re using the Null coalescing operator, so to get back on track, it’s actually expecting:

case .fromPost?:

Instead of:

case .fromPost:

To make this more clear, the types of shortForm and longForm in this snippet I created are the same:

let shortForm: Int? = Int("1")
let longForm: Optional<Int> = Int("2")

You may unwrap it before, or you can declare the destinySearch as an implicitly unwrapped value. Moving onto Travis, please make sure you’re using the latest version of Xcode via:

osx_image: xcode12.2
