I would like to have different fill colors in my chart. What I want to achieve is that if the values drop below 0 the fill color should be red. If they are above the fill color should be red. My code looks as follows: import SwiftUI import Charts struct DataPoint: Identifiable {     let id: UUID = UUID()     let x: Int     let y: Int } struct AlternatingChartView: View {          enum Gradients {         static let greenGradient = LinearGradient(gradient: Gradient(colors: [.green, .white]), startPoint: .top, endPoint: .bottom)         static let blueGradient = LinearGradient(gradient: Gradient(colors: [.white, .blue]), startPoint: .top, endPoint: .bottom)     }          let data: [DataPoint] = [         DataPoint(x: 1, y: 10),         DataPoint(x: 2, y: -5),         DataPoint(x: 3, y: 20),         DataPoint(x: 4, y: -8),         DataPoint(x: 5, y: 15),     ]               var body: some View {         Chart {             ForEach(data) { data in                 AreaMark(                     x: .value("Data Point", data.x),                     y: .value("amount", data.y))                 .interpolationMethod(.catmullRom)                 .foregroundStyle(data.y < 0 ? Color.red : Color.green)                                  LineMark(                 x: .value("Data Point", data.x),                 y: .value("amount", data.y))                 .interpolationMethod(.catmullRom)                 .foregroundStyle(Color.black)                 .lineStyle(StrokeStyle.init(lineWidth: 4))                              }         }         .frame(height: 200)     } } #Preview {     AlternatingChartView() } The result looks like this: I also tried using foregroundStyle(by:) and chartForegroundStyleScale(_:) but the result was, that two separate areas had been drawn. One for the below and one for the above zero datapoints. So, what would be the right approach to have two different fill colors?

Hi, I'm try to convert from CoreData to SwiftData. Problem is that I'm using inheritance in CoreData. So, I have a base class "animal" and "cat" and "bird" inherit from it. I can have a array of type "animal" which contains both cats and dogs. Now as I try to move to SwiftData I tried the following approach protocol Animal { var name: String { get set } } @Model class Cat: Animal { var name: String var legs: Int } @Model class Bird: Animal { var name: String var legs: Int var wings: Int } @Model class Enviroment { //leads to error: //Type 'any Animal' cannot conform to 'PersistentModel' var animals: [any Animal] } So how to I get around of this? I would like to store multiple types of animals (classes that conform to protocol animal) … but how can I achieve that? Thanks

Hi, is there a way to different swift packages for different build configuration? I.e. when I do Release-Builds I'd like to use MyPackage and for debug builds I'd like to use MyPackage-Debug. My first thought was that I could handle this in the Package.swift but .target does not support configurations in .when but only plattforms. So is there any way to use different packages depending on configuration?
