Answer is easy if you debug the code. But it can be tricky to catch by eye. Will it create a entity for this URL = "https://abc.com/aa" ? You can find an answer here: https://bugs.swift.org/browse/SR-2176

UniversalLinkExample.swift

struct UniversalLink {
    public enum Action {
        case none
        case landto
    }

    public let action: Action

    // Will it create a entity for this URL = "https://abc.com/aa"?
    public init?(url: URL) {
        guard let action = UniversalLink.action(from: url.path) else { return nil }

        self.action = action
    }

    private static func action(from path: String) -> Action? {
        switch path {
        case "/aa/landto":
            return .landto
        case "/aa/", "/aa":
            return .none
        default:
            return nil
        }
    }
}
