I created a SwiftChart as below and I would like to have two YAxis, one for amount and the second for count. So, the amount YAxis is a different scale then the count YAxis.
Does anybody have an example of this or shed some light on coding two different YAxis?
Thanks
ForEach(seriesArt) { series in
ForEach(series.chartSeries.chartEntry) {
BarMark(
x: .value("Tier", $0.tier),
y: .value("Price", $0.keyValue)
)
}
.foregroundStyle(by: .value("Count", series.chartCategory))
.position(by: .value("Price", series.chartCategory))
}
}
.frame(width: 400, height: 200)
.chartXAxis {
AxisMarks(position: .bottom, values: .automatic) {
AxisValueLabel()
.foregroundStyle(Color.white)
}
}
.chartYAxis {
AxisMarks(position: .leading, values: .automatic) { value in
AxisGridLine(centered: true, stroke: StrokeStyle(lineWidth: 1))
AxisValueLabel() {
if let intValue = value.as(Int.self) {
Text("\(intValue)")
.font(.system(size: 10))
.foregroundColor(.white)
}
}
}
.chartYAixs - for count sum by tier which needs to be a different scale from the amount YAxis
}
}
}

I understand by default SwiftData uses SQLite database but it can be configured to persist data in XML, binary and even in-memory databases. Does anybody know where SwiftData the SQLite database is located?
I don't see the structured editing popover when I command right click on an IOS SwiftUI project when I create a new project with just "Hello World" like I see in Xcode 13. Am I missing some thing or is this a bug?
Thanks
I have the following test code:
import SwiftUI
struct ContentView: View {
@State private var draggedImages: [UIImage?] = Array(repeating: nil, count: 5)
@State private var savedToDisk = false
var body: some View {
VStack {
HStack {
ForEach(0..<5, id: \.self) { index in
let image = draggedImages[index] ?? UIImage(systemName: "photo")
Image(uiImage: image!)
.resizable()
.frame(width: 80, height: 80)
.padding()
.background(Color.blue)
.foregroundColor(.white)
.cornerRadius(10)
.onDrag {
return NSItemProvider(object: UIImage(systemName: "photo")!)
}
.onDrop(of: ["public.image"], isTargeted: nil) { providers, _ in
providers.first?.loadDataRepresentation(forTypeIdentifier: "public.image") { data, error in
if let data = data, let uiImage = UIImage(data: data) {
draggedImages[index] = uiImage
saveImageToDisk(image: uiImage, imageNumber: index)
}
}
return true
}
}
.alert(isPresented: $savedToDisk) {
Alert(title: Text("Images Saved"), message: Text("The images have been saved to disk."), dismissButton: .default(Text("OK")))
}
Spacer()
}
}
.padding()
}
private func saveImageToDisk(image: UIImage, imageNumber: Int) {
if let imageData = image.pngData() {
do {
let documentsDirectory = try FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false)
let imageUrl = documentsDirectory.appendingPathComponent("image_\(imageNumber).png")
try imageData.write(to: imageUrl)
savedToDisk = true
} catch {
print("Error saving image: \(error)")
}
}
}
}
I can drag and drop as well as the dragged image is save on the second placeholder thru the fifth but not the first When I drag and drop to the first image another files app opens but when I close this the image is not saved. Any Ideas why the first image behaves differently to all the others?
I test on Sonoma and Xcode 15 beta 7, I wil give it a try on Ventura and Xcode 14 later today to see if the same thing happens.

I have the following test code
import SwiftUI
struct ContentView: View {
@State private var field1 = ""
@State private var field2 = ""
@State private var field3 = ""
var body: some View {
VStack {
Form {
Section(header: Text("Input Fields")) {
TextField("Field 1", text: $field1)
TextField("Field 2", text: $field2)
TextField("Field 3", text: $field3)
}
}
List {
ForEach(1..<6) { index in
Text("Item \(index)")
}
}
.listStyle(InsetListStyle())
}
.navigationTitle("Form and List View")
.toolbar {
ToolbarItem(placement: .cancellationAction) {
Button("Dismiss") {
// Handle dismiss action
}
.foregroundStyle(.red) //
}
ToolbarItem(placement: .primaryAction) {
Button("Done") {
// Handle done action
}
.foregroundStyle(.green) //
}
}
}
}
I can't customize the color of the Buttons. Besides .foreground modifier I have tried ..foregroundColor(.red) and .foregroundColor(.green) to no avail. How can I customize the buttons in the toolbar for both macOS and IOS

I am getting the following error on this line of code
@Query(sort: \.id, order: .reverse) private var artList: [ArtInventory]
Cannot infer key path type from context; consider explicitly specifying a root type
So, I select fix and then the line of code then look like this
@Query(sort: \<#Root#>.id, order: .reverse) private var artList: [ArtInventory]
with this error
Invalid component of Swift key path
Some seems to have changed with the @Query macro in beta 5, which now needs a root type, but not sure how to proceed.
Any ideas how to fix?

I have a test project with a bar progress indicator create on Ventura with Xcode 14.3.1., It does not show the any animation until the @IBAction function completes.
I want to show progress as it progresses not a just the end? Any ideas how to fix this?
Below is my test project code..
//
// ViewController.swift
// ProgressTest
//
// Created by Bob on 6/5/23.
//
import Cocoa
class ViewController: NSViewController {
@IBOutlet weak var progressIndicator: NSProgressIndicator!
// var progress: Double = 0.0
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override var representedObject: Any? {
didSet {
// Update the view, if already loaded.
}
}
@IBAction func progressStart(_ sender: Any) {
// Start the progress animation
progressIndicator.startAnimation(self)
// Do some work here...
// Do some work here...
var progress: Double = 0.0
for _ in 0..<100 {
// Update the progress value in a loop
progress += 1.0
progressIndicator.doubleValue = progress
// progress = Double(i)
// progressIndicator.increment(by: 10)
// progressIndicator.doubleValue = progress
// Do some work here...
}
// Stop the progress animation
progressIndicator.stopAnimation(self)
}
}
thanks

The find and replace in project is not working for me in Xcode 14.2 on Ventura 13.2. When I enter the find text as well as the replace text the "Replace" and "Replace All" buttons remained grayed out.
Is this a bug with Xcode or am I missing something?
Please advise.

I want to put some code to be run when my app terminates but the following:
func applicationWillTerminate(_ aNotification: Notification) {
// Insert code here to tear down your application
print("Termination Code")
}
in the AppDelegate class is not called, any ideas how to fix this issue.
I saw this posts https://developer.apple.com/forums/thread/126418 but I do not have an info.plist. I think the info.plist is not longer needed.
The following doc does not have much to say about this??

For a macOS app using Xcode 14.1. I have a bar chart with two bars for each interval. See screen chart below. I want to change the "Invoice" and Payments" text
I can't seem to find a modifier for the Legend text. How do you change the text color for SwiftUI Chart's legend text?
I have a macOS tableview I have a textfield as a column along with an IBAction code to capture the data from this field. I wanted to add continuous spell check for this column .
So, I decided to change the column from a TextField to a ScrollView to take advantage of the continuous spell check. Using Xcode 14 I changed the Cell to a custom Cell. The custom cell has a scrollview object as the object because I want to take advantage of the built in continuous spell checking instead of using a textfield. All is well with this implementation until I tried to add a IBAction code for when I enter text in the scrollview/textView field.
There does not seem to be a way to capture the text? Am I trying to do something that can't be done or is there a way to add continuous spell check to a textField?
I have the following code:
class ChartSeriesRow: ObservableObject {
var id = UUID()
var chartCategory: String
struct ChartSeriesData {
var chartEntry: [ChartData]
}
var chartSeries : ChartSeriesData
struct ChartData: Codable, Identifiable, Hashable {
var id = UUID()
let chartMonth: String
let chartSales: String
}
init() {
chartCategory = ""
chartSeries = ChartSeriesData(chartEntry: [ChartData(chartMonth: "01", chartSales: "10.0") ] )
}
}
How do I populate ChartSeriesData? I thought I could just add the following: However coding this way there is no append method.
extension ChartSeriesRow {
func addRow(chartRow: ChartSeriesData){
ChartSeriesRow.ChartSeriesData.chartEntry.append(contentsOf: chartRow)
}
}
From the class below how do I initialize chartEntry for the structure array? As it is below chartEntry is outside scope of init?
class ChartSeriesRow: ObservableObject {
var id = UUID()
var chartCategory: String
struct chartSeriesData{
var chartEntry: [ChartData]
}
struct ChartData: Codable, Identifiable, Hashable {
var id = UUID()
let chartMonth: String
let chartSales: String
}
init() {
chartCategory = ""
chartEntry = chartSeriesData: [ChartData.chartMonth: "01", ChartData.chartSales: "10.0"]
}
}

Environment : macOS Ventura Xcode beta 14.1:
I have the following chart I was using to learn about SwifUI Charts:
I wanted to have different scales on the leading and trailing yaxis as well as have the first 3 bars to use leading scale and the last two bars use the trailing scale.
Can this be done? If so, how?
Thanks
