Hi, I'm just following up to see if anyone has any thoughts on this.

Hi, Thanks for your response, however I'm not sure where that file would be located. I don't see a database file in my file directory. All I have is the file with the model class.

Hi, Thank you for your response. Using Xcode 15.4, how can I create a git repository for an already existing project? The Source Control tab is blank and I don't see a button to create a repository.

Hi, Just bumping this to see if anyone knows why I'm getting these errors. Please let me know if anymore information is needed.

With this code I get the error: .onChange(of: buttonState) { oldState, newState in } But not with this: .onChange(of: buttonState) { state in } Would it be recommended to use a slightly older target so that more users would be able to access the app?

Hi, I have a follow up question. In an older project, using that code, I get an error: 'onChange(of:initial:_:)' is only available in iOS 17.0 or newer The solution provided is to wrap the code in if #available(iOS 17.0, *) { }, but I'm only able to wrap the whole view inside of it, like so: if #available(iOS 17.0, *) { VStack () { // view with .onChange } } else { VStack () { // view with older solution } } The view is quite lengthy so it would be very redundant to have the same view twice, (the same view for each component of the if/else statement). Is there a way to implement an if statement so that I would only need the code for the view once (something like the code below)? VStack { } if #available(iOS 17.0, *) { .onChange() { } } else { // older solution }

Hi, Thank you for all the help. There was a discrepancy in the bytes because I removed a field from the data set. I was missing the Content-Type: application/json header which caused the issue.

Hi, Thank you for your response. Here is the whole function: func createAccount(account: AccountCreationData, completion: @escaping (Response) -> Void) { guard let url = URL(string: "http://localhost:4300/account/create-account") else { return } var request = URLRequest(url: url) request.httpMethod = "POST" print(account) guard let encoded = try? JSONEncoder().encode(account) else { print("Failed to encode request") return } print(encoded) request.httpBody = encoded URLSession.shared.dataTask(with: request) { (data, response, error) in guard let data = data else { return } do { let resData = try JSONDecoder().decode(Response.self, from: data) DispatchQueue.main.async { completion(resData) } } catch let jsonError as NSError { print("JSON decode failed: \(jsonError)") } }.resume() } Below are print statements of account and encoded: AccountCreationData(name: "name", email: "email", phone: "phone", password: "password") 110 bytes

One thing I now realize is that it's not practical to have a Canvas inside a ScrollView because it interferes with the drawing gesture. However, I'm still unsure of how to draw on a Canvas upon loading.

One thing I have noticed is the Canvas code doesn't run until there's a gesture, and I'm not sure why that is because the documentation has an example that displays a drawing upon loading the Canvas. struct Line { var points: [CGPoint] var color: Color } var body: some View { @State var lines: [Line] = [] Canvas { ctx, size in for line in lines { let color = line.colorName == nil ? getColor(colorName: nil, rgb: line.rgb) : getColor(colorName: line.colorName, rgb: nil) var path = Path() print(line.points) // this is how I noticed this code doesn't run until the gesture runs. This print statement doesn't run upon loading the Canvas path.addLines(line.points) ctx.stroke(path, with: .color(color), style: StrokeStyle(lineWidth: 5, lineCap: .round, lineJoin: .round)) } } .gesture(DragGesture(minimumDistance: 0, coordinateSpace: .local) .onChanged({ value in draw(position: value.location, translation: value.translation) } }) ) .onAppear { lines = parseLinesString() for line in lines { for point in line.points { draw(position: point, translation: nil) } } } func draw(position: CGPoint, translation: CGSize?) { if translation == .zero || translation == nil { lines.append(Line(points: [position], color: color.black)) } else { guard let lastIndex = lines.indices.last else { return } lines[lastIndex].points.append(position) unsaved = true } } } As I mentioned previously, I'm not sure how to translate the documentation example to my application. If anyone could point me in the right direction that would be greatly appreciated. Thank you.

@Claude31 Thank you for your response. Below is revised code, with the ScrollView implemented, so the drawing aspect isn't going to work unless that's removed. I put a comment in .onAppear { } where I'm assuming code needs to be written to plot the points from lines onto the canvas. I looked at the official documentation for canvas' that draws upon loading but I can't seem to figure out how to apply it to what I'm doing. import SwiftUI struct LineData { var points: [CGPoint] var color: Color } struct CanvasExample: View { @State var lines: [LineData] = [] @State var selectedColor: Color = Color.black var body: some View { ScrollView (showsIndicators: false) { VStack { Canvas { ctx, size in for line in lines { var path = Path() path.addLines(line.points) ctx.stroke(path, with: .color(line.color), style: StrokeStyle(lineWidth: 5, lineCap: .round, lineJoin: .round)) } }.gesture(DragGesture(minimumDistance: 0, coordinateSpace: .local) .onChanged({ value in let position = value.location if value.translation == .zero { lines.append(LineData(points: [position], color: selectedColor)) } else { guard let lastIndex = lines.indices.last else { return } lines[lastIndex].points.append(position) } }) ) .onAppear { // code that takes data passed to variable lines and draws on canvas } } } } } #Preview { CanvasExample() } Thank you.

I have two follow up questions. Any help would be greatly appreciated. How can I implement a scroll feature with the Canvas so that the Canvas itself would be larger than the screen? How can I draw on the canvas upon loading the canvas? For example, if I pass data stored as a Line variable to the view that the Canvas is on, how can I draw onto the canvas upon loading based off of that data? Thank you.

@sha921 @thibautrichez Thank you for your responses. I get the following errors with the code below: Button { login() } label: { ZStack { RoundedRectangle(cornerRadius: 5) .fill(Color.black) .frame(width: UIScreen.main.bounds.width - 50, height: 50) Text("Sign in") .foregroundColor(.white) } } func login() { print("test") } Incorrect argument label in call (have '_: label:', expected 'value:selected:') Trailing closure passed to parameter of type 'String' that does not accept a closure Thank you again for the help so far.
