Я передаю объект Venue из PreferencesVC в DiscoverVC, объявив экземпляр класса и установив переменную venue для передаваемого объекта.
К моменту выполнения кода beginLoadView() объект Venue равен nil и, следовательно, оператор if некорректно выполняет
Вывод на консоль:
Class PreferencesVC: UIViewController{
@IBAction func doneBtnTapped(_ sender: Any) {
print("inside doneBtnTapped selectedVenue.name: \(selectedVenue?.name ?? "selectedVenue is nil")")
guard let discoverVC = storyboard?.instantiateViewController(withIdentifier: "DiscoverVC") as? DiscoverVC else { return }
discoverVC.venue = self.selectedVenue!
DataService.run.updateUserDiscoveryPreferences(forUID: Auth.auth().currentUser!.uid, discoverableBool: discoverable!, preferences: preferences) { (success) in
self.dismissDetail()
}
}//end func
}
Class DiscoverVC: UIViewController{
var venue: Venue?{
didSet{
print("DiscoverVC venue name: \(venue?.name ?? "venue name")")
}
}
override func viewWillDisappear(_ animated: Bool) {
print("inside viewWillDisappear")
venue = nil
}//end func
override func viewWillAppear(_ animated: Bool) {
print("inside viewWillAppear")
beginLoadView()
}
func beginLoadView(){
