My project works fine on one MacBook, but after I transfering it to another MacBook, it crashes.Here is a part of my code:func MusicPlay() { Playnow = true self.ipv.start() self.playButton.isHidden = true self.pauseButton.isHidden = false var path = Bundle.main.path(forResource:music!,ofType :"mp3") if Initial == true{ path = Bundle.main.path(forResource:music!,ofType :"mp3") } else{ switch music { case "Viva La Vida": path = Bundle.main.path(forResource:"result1",ofType :"mp3") case "Something Just Like This": path = Bundle.main.path(forResource:"result2",ofType :"mp3") case "Señorita": path = Bundle.main.path(forResource:"result3",ofType :"mp3") default: path = Bundle.main.path(forResource:music!,ofType :"mp3") } } let soundUr1 = URL(fileURLWithPath: path!) do{ try audioPlayer = AVAudioPlayer(contentsOf: soundUr1) audioPlayer.volume = 1.0 audioPlayer.numberOfLoops = -1 audioPlayer.delegate = self audioPlayer.play() } catch{ print(error) } }After choosing a music at tableView, it performs the function "MusicPlay",and then the project crashes at line 26:try audioPlayer = AVAudioPlayer(contentsOf: soundUr1)Error message:2020-02-15 22:47:22.013016+0800 InteractivePlayerView[6645:253620] [plugin] AddInstanceForFactory: No factory registered for id <CFUUID 0x6000004d7120> F8BB1C28-BAE8-11D6-9C31-00039315CD46What should I do to address this problem?

When I run my project,it crashes quickly,with error message:"Unknown class _TtC10Soul_Music27CollectionViewSlantedLayout in Interface Builder file.""Soul_Music" is the name of my project and "CollectionViewSlantedLayout" is a class at my project.I'm sure that there is no class called "_TtC10Soul_Music27CollectionViewSlantedLayout".How to address this problem?Thanks in advance.

I am working on show weather project. I am listing the cities from database. When I click on a city, another viewcontroller should open. But when I click on a city, the didSelectRowAtIndexPath function does not work.Here is the my code:import UIKit import SCLAlertView import Popover class UserInfoViewController: UIViewController,UIImagePickerControllerDelegate,UINavigationControllerDelegate{ fileprivate var texts = ["Los Angeles", "New York", "Chicago"] fileprivate var popover: Popover! fileprivate var popoverOptions: [PopoverOption] = [ .type(.auto), .blackOverlayColor(UIColor(white: 0.0, alpha: 0.6)) ] @IBOutlet var compositionNum: UILabel! @IBOutlet var fans: UILabel! @IBOutlet var location: UILabel! @IBOutlet var userName: UILabel! @IBOutlet var userImag: UIImageView! @IBOutlet var imagBt: UIButton! @IBAction func modifyInfo(_ sender: Any) { let alert = SCLAlertView() let textField1 = alert.addTextField(userName.text) let textField2 = alert.addTextField(location.text) alert.addButton(“Done”) } } @IBOutlet var topButton: UIButton! @IBAction func expandSet(_ sender: Any) { self.popover = Popover(options: self.popoverOptions) let tableView = UITableView(frame: CGRect(x: 0, y: 0, width: self.view.frame.width-250, height: 120)) tableView.delegate = self tableView.dataSource = self tableView.isScrollEnabled = false tableView.allowsSelection = true self.popover.show(tableView, fromView: self.topButton) } @IBAction func modifyImag(_ sender: Any) { showBottomAlert() } override func viewDidLoad() { super.viewDidLoad() view.bringSubviewToFront(userImag) view.bringSubviewToFront(imagBt) } func photos() { self.showBottomAlert() } func showBottomAlert(){ let alert = SCLAlertView() } func goCamera(){ if UIImagePickerController.isSourceTypeAvailable(.camera){ let cameraPicker = UIImagePickerController() cameraPicker.delegate = self cameraPicker.allowsEditing = true cameraPicker.sourceType = .camera self.present(cameraPicker, animated: true, completion: nil) } else { SCLAlertView().showError("",subTitle: "",closeButtonTitle: "") } } func goImage(){ let photoPicker = UIImagePickerController() photoPicker.delegate = self photoPicker.allowsEditing = true photoPicker.sourceType = .photoLibrary self.present(photoPicker, animated: true, completion: nil) } func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) { let image : UIImage = info[UIImagePickerController.InfoKey.editedImage] as! UIImage userImag.image = image userImag.layer.cornerRadius = userImag.frame.size.width / 2 self.dismiss(animated: true, completion: nil) } } extension String{ var isBlank:Bool{ return allSatisfy({$0.isWhitespace}) } } extension UserInfoViewController: UITableViewDelegate { func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) { self.popover.dismiss() } } extension UserInfoViewController: UITableViewDataSource{ func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int{ return 3 } func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = UITableViewCell(style: .default, reuseIdentifier: nil) cell.textLabel?.text = self.texts[(indexPath as NSIndexPath).row] return cell } func tableView(_ tableView: UITableView, didSelectRowAtIndexPath indexPath: IndexPath) { if(indexPath.row == 0){ let storyboard = UIStoryboard(name: "Main", bundle: nil) guard let secondVC = storyboard.instantiateViewController(withIdentifier: "Main") as? MainViewController else { return } self.present(secondVC, animated: true, completion: nil) } else if(indexPath.row == 1){ } else{ } } }What should I do to make it correct?Thanks in advance.
