SwiftUI 崩溃 &lt;&lt; <opaque return type of view.contextmenu<a> （菜单项：）&gt;&gt;</opaque>

Question

我注意到一些崩溃，但我似乎真的找不到崩溃的任何具体原因，Xcode 也没有帮助我识别它。 QueryLogView.body.getter和ActiveInstance.swift:43都是代码中的空行，我不确定closure in closure in closure能告诉我什么。

也许它与报告中的第 3 行partial apply... 有人知道在哪里看吗？

编辑：

这是QueryLogView中我使用.contextMenu的代码：

ForEach(filterQueries(array: queries.data), id: \.self) { query in
    NavigationLink(destination: QueryDetailView(query: query, instance: intIDtoInstance(Int(query.last ?? "1"))).environmentObject(self.state)) {
        QueryRow(headline: .all, instance: self.activeInstance, query: query)
            .contextMenu {
                Section {
                    Button(action: {
                        self.showSheet = .queriesToDomain(query[2])
                    }) {
                        Text("view_queries_to_domain")
                        Image(systemName: "doc.text.magnifyingglass")
                    }
                    Button(action: {
                        self.showSheet = .queriesToClient(query[3])
                    }) {
                        Text("view_queries_from_client")
                        Image(systemName: "doc.text.magnifyingglass")
                    }
                }
                Section {
                    if #available(iOS 14.0, *) {
                        if let domainURL = URL(string: "https://\(query[2])") {
                            Link(destination: domainURL, label: {
                                Text("visit_domain")
                                Image(systemName: "network")
                            })
                        }
                    }
                    Button(action: {
                        UIPasteboard.general.string = query[2]
                    }) {
                        Text("copy_domain")
                        Image(systemName: "doc.on.doc")
                    }
                    Button(action: {
                        UIPasteboard.general.string = query[3]
                    }) {
                        Text("copy_hostname_or_ip")
                        Image(systemName: "doc.on.doc")
                    }
                }
                Section {
                    Button(action: {
                        addToList(query)
                    }) {
                        Text("add_to_list_dots")
                        Image(systemName: "shield.lefthalf.fill")
                    }
                }
            }
    }.modify {
        if #available(iOS 15.0, *) {
            $0.swipeActions(edge: .leading, allowsFullSwipe: true) {
                Button {
                    addToList(query)
                } label: {
                    Label(queryToListTuple(query).list, systemImage: "shield.lefthalf.fill")
                }.tint(queryToListTuple(query).color)
            }
        } else {
            $0
        }
    }
    #if targetEnvironment(macCatalyst)
    .padding(.horizontal, -12)
    #endif
}

.modify用于具有基于 iOS 版本的条件修饰符：

extension View {
    func modify<T: View>(@ViewBuilder _ modifier: (Self) -> T) -> some View {
        return modifier(self)
    }
}

发现删除所有出现的.modify修复了崩溃。 不知道实际上出了什么问题，但它似乎可以解决它。
