Best way to work with store hours in Swift

Question

I'm building an app in Swift that will take in a store's hours from Firebase and want to represent it in my code as something like "monday.close" to get 02:30. What's the best way to do something like this? Pic below is what the data looks like in Firebase.

init(dictionary: [String: Any]) {
    //initialize food item here
    self.name = dictionary["name"] as? String ?? ""
    self.address = dictionary["address"] as? String ?? ""
    self.restaurantLogo = UIImage(named: "")
    self.menuItems = dictionary["menuItems"] as? [Food] ?? []
    self.deliverUberEats = dictionary["uberEatsLink"] as? String ?? ""
    self.deliverDoorDash = dictionary["doordashLink"] as? String ?? ""
    self.deliverGrubhub = dictionary["grubhubLink"] as? String ?? ""
    self.restaurantID = ""
    self.priceRange = dictionary["price"] as? Int ?? 0
    self.hoursOpen = dictionary["hours"] as? [String : [String: String]]
}

struct RestaurantHours {
    var MonOpen: Date?
    var MonClose: Date?
}
