Hi, is there any possibility to localize my Swift Playgrounds APP? In the Build meta data it is always only English, and the "traditional" localization process doesn't work in Swift Playgrounds on iPad or in Xcode on Mac.

Is there a Form where I, a noobie, can ask really basic questions about this learning environment? As an example, I discovered the semi-colon in doing a task in the early part of "learn to Code" but I have not found any documentation for it. I am sure I will have other questions but right now I am just looking for a place to ask them. Thank you in advance.

Can it be done? I can reliably crash Xcode by attempting the following in a playground: import UIKit import WeatherKit import CoreLocation let sanFrancisco = CLLocation(latitude: 37.7749, longitude: 122.4194) let weatherService = WeatherService() let weather = try await weatherService.weather(for: sanFrancisco) let temperature = weather.currentWeather.temperature print(temperature) Xcode 14.3.1 macOS 13.4.1

I'm encountering the same problem, the chart view stays blank! The code supposed to draw a PiChart with a customization in its style. The exercise is as follows: Pie Charts, Revisited The new API for pie charts exposes two new types: PieWedge and PieChartView. The PieWedge struct gives you several ways to create visual effects with pie charts. It has the following properties: proportion: The percentage of the pie occupied by the wedge, expressed as a Double. color: The color of the wedge. You can use any one of the following values. (Remember to use a period before the color name. If you don't, Swift will return a "use of unresolved identifier" error.) .black .blue .brown .cyan .darkGray .gray .green .lightGray .magenta .orange .purple .red .yellow scale: The radius of the wedge relative to the pie's natural radius, expressed as a Double. Less than 1.0 will make the wedge smaller than normal-sized wedges, and greater than 1.0 will make the wedge larger (typically the desired effect). offset: The distance a wedge lies from the center of the pie, relative to the size of the wedge. An offset of 0 keeps the wedge at the center of the pie. An offset of 1.0 moves the center point of the wedge to where its outer edge would be. The makePieChart() function creates an instance of a PieChartView named pieChartView. PieChartView has one property named wedges, which is an array of PieWedge instances. Assign an array of wedges to this property, or use the append() method of Array to add them one at a time. Keys makePieChart() also creates a key named keyView. It's an instance of ChartKeyView, which has a keyItems property. keyItems is an array of ChartKeyItem instances. ChartKeyItem has the following properties: color: The color swatch displayed in the key. You can use any of the following values. .black .blue .brown .cyan .darkGray .gray .green .lightGray .magenta .orange .purple .red .yellow name: The text to display expressed as a String. Create a pie chart using your own data. Play with different scale and offset properties to see how they affect the look of your chart. My Code: makePieChart() let myPiWedge1 = PieWedge(proportion: 0.1, color: .red, scale: 1.0, offset: 1.0) let myPiWedge2 = PieWedge(proportion: 0.4, color: .blue, scale: 1.0, offset: 1.0) let myPiWedge3 = PieWedge(proportion: 0.5, color: .yellow, scale: 1.0, offset: 1.0) var myPieChartViewArray = PieChartView().wedges myPieChartViewArray = [myPiWedge1, myPiWedge2, myPiWedge3] var myKeyView = keyView.keyItems let myChartKeyItem1 = ChartKeyItem(color: .red, name: "w1") let myChartKeyItem2 = ChartKeyItem(color: .blue, name: "w2") let myChartKeyItem3 = ChartKeyItem(color: .yellow, name: "w3") myKeyView = [myChartKeyItem1, myChartKeyItem2, myChartKeyItem3] I tried this as well, it shows the same issue: makePieChart () //Create an array of PieWedge instances var wedges: [PieWedge] = [] // Create individual PieWedge instances and add them to the wedges array let wedge1 = PieWedge(proportion: 0.3, color: .red, scale: 1.0, offset: 0) let wedge2 = PieWedge(proportion: 0.2, color: .blue, scale: 0.8, offset: 0.2) let wedge3 = PieWedge(proportion: 0.5, color: .green, scale: 1.2, offset: 0) wedges.append(wedge1) wedges.append(wedge2) wedges.append(wedge3) // Create an instance of PieChartView and assign the wedges array let pieChartView = PieChartView() pieChartView.wedges = wedges // Create an instance of ChartKeyView and configure its keyItems array let keyItem1 = ChartKeyItem(color: .red, name: "Red Wedge") let keyItem2 = ChartKeyItem(color: .blue, name: "Blue Wedge") let keyItem3 = ChartKeyItem(color: .green, name: "Green Wedge") let keyItems = [keyItem1, keyItem2, keyItem3] let keyView = ChartKeyView() keyView.keyItems = keyItems Any one can help? to me it sounds that the playground has some bug in it :) This exercise from the book "Explorations": Exploration --> Student --> 3-Organizing Data --> 2-Play with Complex Data --> I-Visualization Revisited

Hi, I have a problem with making a swift playgrounds app walkthrough. I followed the steps exactly and modified my Package.swift a bit (in the targets section): .executableTarget(name: "App", dependencies: ["Guide"], path: "App"),         .target(             name: "Guide",             path: "Guide",             resources: [             .process("Guide.tutorial"),             ]) Now when I open the project in Playgrounds I get this error: public headers ("include") directory path for 'Guide' is invalid or not contained in the target Any help would be appreciated. Thanks

I just started to learn how to code with "Intro to App Development With Swift" from Apple on iBooks and whenever I try to edit one of the given practice files, a window pops up saying "The document “02_Naming.playground” could not be saved. The file has been changed by another application. Click Save Anyway to keep your changes and save the changes made by the other application as a version, or click Revert to keep the changes from the other application and save your changes as a version. You can also click Save As to save your changes to a different file." This error pops up every time I type a keystroke in the file. How do I fix this?
