我使用Branch框架时应用程序崩溃

Question

我使用Branch SDK获取iOS应用程序的深层链接。如果您快速向第三方应用程序（例如，Slack，Facebook）发送深层链接，则会出现问题，然后发生应用程序崩溃。控制台显示以下结果import UIKit import CoreData class ItemDetailsVC: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource { @IBOutlet weak var storePicker: UIPickerView! @IBOutlet weak var detailsField: CustomTextField! @IBOutlet weak var priceField: CustomTextField! @IBOutlet weak var titleField: CustomTextField! var stores = [Store]() var itemToEdit: Item? override func viewDidLoad() { super.viewDidLoad() storePicker.delegate = self storePicker.dataSource = self // let store = Store(context: context) // store.name = "Amazon" // let store1 = Store(context: context) // store1.name = "Flipkart" // let store2 = Store(context: context) // store2.name = "Snapdeal" // let store3 = Store(context: context) // store3.name = "Bigbasket" // let store4 = Store(context: context) // store4.name = "Groffers" // ad.saveContext() getStores() if itemToEdit != nil{ loadItemData() } if let topItem = self.navigationController?.navigationBar.topItem { topItem.backBarButtonItem = UIBarButtonItem(title: "", style: UIBarButtonItemStyle.plain, target: nil, action: nil) } // Do any additional setup after loading the view. } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? { let store = stores[row] return store.name } func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int { return stores.count } func numberOfComponents(in pickerView: UIPickerView) -> Int { return 1 } func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) { //Update } func getStores(){ let fetchRequest: NSFetchRequest<Store> = Store.fetchRequest() do{ self.stores = try context.fetch(fetchRequest) self.storePicker.reloadAllComponents() }catch{ //Handles the error } } @IBAction func savePressed(_ sender: Any) { var item: Item! if itemToEdit == nil{ item = Item(context: context) }else{ item = itemToEdit } if let title = titleField.text{ item.title = title } if let price = priceField.text{ item.price = (price as NSString).doubleValue } if let details = detailsField.text{ item.details = details } item.toStore = stores[storePicker.selectedRow(inComponent: 0)] navigationController?.popViewController(animated: true) } func loadItemData(){ if let item = itemToEdit{ titleField.text = item.title priceField.text = "\(item.price)" detailsField.text = item.details if let store = item.toStore{ var index = 0 repeat{ let s = stores[index] if s.name == store.name{ storePicker.selectRow(index, inComponent: 0, animated: false) break } index += 1 }while index < stores.count } } } } 如何解决？

我的代码

[core] SLComposeViewController dealloc <SLComposeViewController: 0x11fbf03a0>.
