Hi,create macOS project and I try to make UIViewRepresentable but get this error.import SwiftUI
struct WebView: UIViewRepresentable { //Error: Use of undeclared type 'UIViewRepresentable'
}What can I do with it or how can I make my own UIViewRepresentable for macOS to use WKWebView in my project?struct WebView: UIViewRepresentable {
func makeUIView(context: Context) -> WKWebView {
WKWebView()
}
func updateUIView(_ uiView: WKWebView, context: Context) {
}

I don't understand when I try to remove all items by calling viewContext.execute(deleteRequest) SwiftUI doesn't redraw UI. I see items from sqlite are gone.
swift
struct CloudKitTestView: View {
@Environment(\.managedObjectContext) private var viewContext
@FetchRequest(
sortDescriptors: [NSSortDescriptor(keyPath: \Item.timestamp, ascending: true)],
animation: .default)
private var items: FetchedResultsItem
var body: some View {
VStack {
Button("Remove all") {
let fetchRequest = NSFetchRequestNSFetchRequestResult(entityName: "Item")
let deleteRequest = NSBatchDeleteRequest(fetchRequest: fetchRequest)
do {
try viewContext.execute(deleteRequest)
} catch {
// Replace this implementation with code to handle the error appropriately.
// fatalError() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development.
let nsError = error as NSError
fatalError("Unresolved error \(nsError), \(nsError.userInfo)")
}
}
List {
ForEach(items) { item in
Text("Item at \(item.timestamp!, formatter: itemFormatter)")
}
.onDelete(perform: deleteItems)
}
.toolbar {
#if os(iOS)
EditButton()
#endif
Button(action: addItem) {
Label("Add Item", systemImage: "plus")
}
}
}
}
private func addItem() {
withAnimation {
let newItem = Item(context: viewContext)
newItem.timestamp = Date()
do {
try viewContext.save()
} catch {
// Replace this implementation with code to handle the error appropriately.
// fatalError() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development.
let nsError = error as NSError
fatalError("Unresolved error \(nsError), \(nsError.userInfo)")
}
}
}
private func deleteItems(offsets: IndexSet) {
withAnimation {
offsets.map { items[$0] }.forEach(viewContext.delete)
do {
try viewContext.save()
} catch {
// Replace this implementation with code to handle the error appropriately.
// fatalError() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development.
let nsError = error as NSError
fatalError("Unresolved error \(nsError), \(nsError.userInfo)")
}
}
}

I face an issue when I put WKWebView to View. As you can see Web page doesn't show from the begin.When I change the app window size the page shows correctly.What could be the problem?import SwiftUI
import WebKit
struct WebView: NSViewRepresentable {
func makeNSView(context: Context) -> WKWebView {
let view = WKWebView()
guard let url = URL(string: "https://github.com/filimo/ReaderTranslator") else { return view }
view.load(URLRequest(url: url))
return view
}
func updateNSView(_ view: WKWebView, context: Context) {
}
}
struct WKWebViewDemo: View {
var body: some View {
WebView()
}
}I left the link with images on https://stackoverflow.com/q/58491837/4067700If I added Text with multiple lines then WebView is trunced of the top.var body: some View {
VStack {
Text("line\nline\nline\nline\nline\nline\nline\nline\nline\nline\nline\nline\n")
WebView()
}
}
