crashlytics 中报告了崩溃。部分应用于闭合 #1

问：

我在 crashlytics 中收到了关于部分应用于关闭的崩溃报告。我尝试过其他主要集中在使用[弱自我]的答案，但这没有帮助。但是，我的设备没有崩溃。 根据报告，崩溃发生在函数的某个地方，我在这里显示我的 dropDown 是代码

func showDropDown(_ names: [String], forResult result: SearchPatientResultResponnse) {
        guard let vc = viewController
        else { return }
        self.searchedPatientNames = result.data?.patientSearchSuggestions
        Helpers.showSearchDropdown(anchorView: vc.searchBar.searchTextField, dataSource: names, scrollToTop: true, completion: { [weak self] (i, item) in
            guard let self = self else {
                return
            }
            vc.searchBar.text = item
            vc.dismissKeyboard()
            self.selectedSearchPatient = self.searchedPatientNames?[i]
            if let d = self.searchedPatientNames?[i].dob {
                vc.dobTF.text = DateTimeFormatters.userUIDateFormatterInUTC.string(from: d)
            }
            self.search(self.selectedSearchFilter)
        }, fetchPaginationData: { [weak self] in
            guard let self = self, !self.isNameSearchLastPage, self.page != -1 else {
                return
            }
            vc.searchBar.isLoadingWithoutSearchIcon = true
            self.fetchPatientNameNextPage()
        }, cancel: { [weak self] in
            self?.resetPaginationParams()
        })
    }

这是我调用此showDropDown函数的函数

    func getQueryPatientResponse() {
        guard let vc = viewController else {
            return
        }
        SocketIOManager.shared.queryResponseForPatient = { [weak self] result in
            var names: [String] = []
            self?.isNameSearchLastPage = result.data?.isLastPage ?? true
            self?.page = result.data?.pageNumber ?? -1
            for data in result.data?.patientSearchSuggestions ?? [] {
                var name = ""
                if !data.middleName.isEmpty {
                    name = data.firstName + " " + data.middleName + " " + data.lastName
                } else {
                    name = data.firstName + " " + (data.lastName)
                }
                names.append(name)
            }
            vc.searchBar.isLoadingWithoutSearchIcon = false
            self?.page == 1 ? self?.showDropDown(names, forResult: result) : self?.updateDropDown(names, forResult: result)
        }
    }

这是crashlytics的崩溃报告：-
