this maybe of use: let now = Date() let startOfDay = Calendar.current.startOfDay(for: now) print("startOfDay: \(startOfDay)") You can format the date, like: let formatter = DateFormatter() formatter.dateStyle = .full formatter.timeStyle = .medium print(" now: \(formatter.string(from: now)) \n startOfDay: \(formatter.string(from: startOfDay))")

glad it helped. As for the Core Data Fetch Request question, show us the code you are using.

definitely things have changed in macOS 11.3 beta. This is what I get when I start the app, click in the 1st text field, then click in the 2nd text field. I never get any "commit" unless I press the return key. changed 1 changed 1 changed 2

Maybe I don't understand the question properly, but I'm not getting a "onCommit" trigger when changing the focus. Using xcode 12.5-beta, macos 11.3-beta, targets ios 14.x, catalyst 11.3 with the following test code: struct ContentView: View { @State var searchQuery1 = "" @State var searchQuery2 = "" var body: some View { VStack { TextField("TextField 1", text: $searchQuery1){ _ in print("changed 1") } onCommit: { print("----- commit 1") } // only when the return key is pressed // another TextField to change focus TextField("TextField 2", text: $searchQuery2, onEditingChanged: { _ in print("changed 2") }, onCommit: { print("commit 2") } ) // a button to change focus Button(action: {print("button action")}) { Text("button") } } } }

it's not really clear what you are asking. The following code shows how you could navigate to "different views" from your list. struct ContentView: View { let contacts = [ Settings(imageName: "image1", name: "NumberOne"), Settings(imageName: "image2", name: "NumberTwo"), Settings(imageName: "image3", name: "NumberThree"), Settings(imageName: "image4", name: "NumberFour"), ] var body: some View { NavigationView { List(contacts) { contact in NavigationLink(destination: NumberView(contact: contact)) { ContactRow(contact: contact) } } .navigationBarTitle("Contacts") }.environment(\.colorScheme, .light) } } struct ContactRow: View { let contact: Settings var body: some View { HStack { Image(contact.imageName) .resizable() .aspectRatio(contentMode: .fill) .frame(width: 20, height: 20) VStack(alignment: .leading) { Text(contact.name) .font(.system(size: 21, weight: .medium, design: .default)) } } } } struct Settings: Identifiable { let imageName: String let name: String let id = UUID() } struct NumberView: View { let contact: Settings var body: some View { Text("view: \(contact.name)") } } Is this what you are looking for?

you can achieve what you want with the following, but it is not a good idea to structure your code this way. The NumberView should be generic and deal with the different "contact" as required, not a different separate view for different contact. Imagine if you have 100 contacts, then you would need 100 different views. struct NumberView: View { let contact: Settings var body: some View { switch contact.name { case "NumberOne": NumberOneView(contact: contact) case "NumberTwo": NumberTwoView(contact: contact) case "NumberThree": NumberThreeView(contact: contact) case "NumberFour": NumberFourView(contact: contact) default: NumberOneView(contact: contact) } } } struct NumberOneView: View { let contact: Settings var body: some View { Text("NumberOneView: \(contact.name)") } } struct NumberTwoView: View { let contact: Settings var body: some View { Text("NumberTwoView: \(contact.name)") } } struct NumberThreeView: View { let contact: Settings var body: some View { Text("NumberThreeView: \(contact.name)") } } struct NumberFourView: View { let contact: Settings var body: some View { Text("NumberFourView: \(contact.name)") } }

Just to let you know, I tested your code as a macOS app, using xcode 12.5-beta on macos 11.3-beta and all is working well for me with or without the DispatchQueue.main.async.

have a look at this answer on Stack Overflow: https://stackoverflow.com/questions/66301334/swiftui-datepicker-day-of-week-language

you have the ") - Error Here }" the wrong way around. It should be: navigationBarItems(trailing: Button(action: { print("Hello") }) { Image(systemName: "square.and.pencil") .resizable() .frame(width: 50, height: 50) }) - Error not Here

Instead of sending a String I would send a message (MyMessage) where you can include a type, for example: public struct MyMessage: Codable { var type: Int // 0=word, 1=answer var data: String // the string value public init(type: Int, data: String) { self.type = type self.data = data } } You will have to encode/decode this, then you can find what type of message you received: func session(_ session: MCSession, didReceive data: Data, fromPeer peerID: MCPeerID) { if let response = try? MyMessage.decode(from: data) { DispatchQueue.main.async { if response.type == 0 { self.dictionaryValues["word"] = response.data } else { self.dictionaryValues["answer"] = response.data } } } else { // deal with no data } }

how about just this: let img = UIImage(...) img.pngData() // the data to be saved as png

Yes, as I said, you have to encode/decode this. Try this: extension Encodable { func encode(with encoder: JSONEncoder = JSONEncoder()) throws - Data { return try encoder.encode(self) } } extension Decodable { static func decode(with decoder: JSONDecoder = JSONDecoder(), from data: Data) throws - Self { return try decoder.decode(Self.self, from: data) } } func randomWordSession() { guard let word = try? MyMessage(type: 0, data: dictionaryValues["word"] ?? "").encode() else { return } ... } func answerSession() { guard let answer = try? MyMessage(type: 1, data: dictionaryValues["answer"] ?? "").encode() else { return } ... }

this is untested, you could try something like this: Image(...).highPriorityGesture( DragGesture(minimumDistance: 1, coordinateSpace: .global) .onChanged { let theCGPoint = $0.location ... })

nice solution and article from SwiftUI-Lab. It seems you could achieve something similar with just the following: (let me know if this works for you) struct ContentView: View { var mouseLocation: NSPoint { NSEvent.mouseLocation } @State var overImg = false var body: some View { Image(systemName: "clock").resizable().frame(width: 444, height: 444) .onHover { over in overImg = over } .onAppear(perform: { NSEvent.addLocalMonitorForEvents(matching: [.mouseMoved]) { if overImg { print("mouse: \(self.mouseLocation.x) \(self.mouseLocation.y)") } return $0 } }) } }

you are missing these frameworks: import SwiftUI import CoreLocation
