Any reources available to learn advanced animation from scratch it would be helpful if someone mentions any resiurces thank you

I have created the .json file according to the https://developer.apple.com/documentation/createml/building-an-object-detector-data-source here is my .json file below     {         "imagefilename":"Five Fingers.HEIC",         "annotation": [             {                 "coordinates": {                     "y": 156.062,                     "x": 195.122,                     "height": 148.872,                     "width": 148.03                 },                 "label": "Five Fingers"             }         ]     },     {         "imagefilename": "One Finger.HEIC",         "annotation": [             {                 "coordinates": {                     "y": 156.062,                     "x": 195.122,                     "height": 148.872,                     "width": 148.03                 },                 "label": "One Finger"             }         ]     },     {         "imagefilename": "Two Finger.HEIC",         "annotation": [             {                 "coordinates": {                     "y": 156.062,                     "x": 195.122,                     "height": 148.872,                     "width": 148.03                 },                 "label": "Two Finger"             }         ]     },     {         "imagefilename": "Four Finger.HEIC",         "annotation": [             {                 "coordinates": {                     "y": 156.062,                     "x": 195.122,                     "height": 148.872,                     "width": 148.03                 },                 "label": "Four Finger"             }         ]     }     ] but it shows error as Missing required column 'label' in json. at "NameOfJsonFile.json" Were am I Wrong

As I’m interested to make HomeKit accessory while searching in the internet i found out that hobbyist can make HomeKit accessary without MFI license the link is given below https://mfi.apple.com/en/who-should-join.html but it says to download HAP Specification which is pdf containing all the information regarding interacting with Apple devices with HomeKit Accessories but im not able to see any pdf in the give link can anyone say where will be the pdf is present to download Thank you in advance

I have requested the access from the HealthKit by below code let calorieCount = HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.activeEnergyBurned)! and it working perfectly but not able to read the data using Query after reading the documentation I have found out HKStatisticsQuery is used for Query     func CaloriesBurned() {         let activeEnergy = HKQuantityType.quantityType(forIdentifier: .activeEnergyBurned)!         let startDate = Calendar.current.date(byAdding: .day,value: -7, to: Date())         let predicate = HKQuery.predicateForSamples(withStart: startDate, end: Date(), options: .strictStartDate)         let query = HKStatisticsQuery(quantityType: activeEnergy, quantitySamplePredicate: predicate,completionHandler: <#T##(HKStatisticsQuery, HKStatistics?, Error?) -> Void#>))     } but I don't understand what should be written in completion handler in above code to read the active Energy Burned I have read already documentation if anyone has sample code to read energy burned or sample code on how to use HKStatisticsQuery

I wanted to make a Gauge View to display the angle Moved below is the image and the needle give the angle according to the input is given ,but I need to change the direction of the needle with some animation as of now its just moving like a glitch below is my code import SwiftUI struct RudderView: View {     @State var ArrowValue: CGFloat = -100     let AngleTimer = Timer.publish(every: 0.1, on: .main, in: .common).autoconnect()     var body: some View {         NavigationView {             ZStack{                     Circle()                         .stroke(.gray.opacity(0.1),lineWidth: 25)                     Circle()                         .trim(from: 0,to: 0.75)                         .stroke(Gradient(colors: [.red,.white,.green]), style: StrokeStyle(lineWidth: 25,lineCap: .round,lineJoin: .round))                         .rotationEffect(Angle(degrees: -225))                                   ZStack {                         RoundedRectangle(cornerRadius: 20)                             .foregroundColor(.white)                             .frame(width: 25, height: 150)                     }                     .offset(x:0, y: -50)                     .rotationEffect(Angle(degrees: ArrowValue))                     .onReceive(AngleTimer) { _ in                         withAnimation {                                                              }                         }                     }                     Text("40")                         .font(.largeTitle)                         .fontWeight(.thin)                         .foregroundColor(.white)                         .offset(x:100, y:170)                     Text("-40")                         .font(.largeTitle)                         .fontWeight(.thin)                         .foregroundColor(.white)                         .offset(x:-100, y:170)             }             .padding()         }                      }             } struct RudderView_Previews: PreviewProvider {     static var previews: some View {         RudderView()             .preferredColorScheme(.dark)     }]w } can anyone say what to type in the animation bracket to move my needle smoothly according to the changes of input for arrow

I have created Swift Charts using Ready Made Data Like below static let last12Months = [ (month: date(year: 2022, month: 6), KW: 3952, dailyAverage: 127, dailyMin: 95, dailyMax: 345), (month: date(year: 2022, month: 7), KW: 8322, dailyAverage: 124, dailyMin: 55, dailyMax: 255), (month: date(year: 2022, month: 8), KW: 2952, dailyAverage: 245, dailyMin: 99, dailyMax: 673), (month: date(year: 2022, month: 9), KW: 3352, dailyAverage: 875, dailyMin: 92, dailyMax: 623), (month: date(year: 2022, month: 10), KW: 3252, dailyAverage: 257,dailyMin: 55, dailyMax: 675), (month: date(year: 2022, month: 11), KW: 3232, dailyAverage: 537,dailyMin: 65, dailyMax: 643), (month: date(year: 2022, month: 12), KW: 9871, dailyAverage: 253,dailyMin: 25, dailyMax: 987), (month: date(year: 2023, month: 1), KW: 8623, dailyAverage: 235, dailyMin: 96, dailyMax: 353), (month: date(year: 2023, month: 2), KW: 7612, dailyAverage: 276, dailyMin: 64, dailyMax: 765), (month: date(year: 2023, month: 3), KW: 2335, dailyAverage: 978, dailyMin: 36, dailyMax: 456), (month: date(year: 2023, month: 4), KW: 9087, dailyAverage: 667, dailyMin: 63, dailyMax: 675), (month: date(year: 2023, month: 5), KW: 2823, dailyAverage: 865, dailyMin: 100, dailyMax: 765), (month: date(year: 2023, month: 6), KW: 9762, dailyAverage: 544, dailyMin: 36, dailyMax: 999), ] `but now I want to create same charts with real world reading like Health App. For example aim taking the sensor value through bluetooth, I can show the reading from sensor to app but how can I store the data for months and show them in Charts Any Ideas where am I lagging`

I have just started to learn Storyboard While I was Creating the View Controller, the Assistant doesn't open up to opens up only for navigation controller. I have like 2 View Controller, Assistant doesn't showing up for those two of them. can anyone point out where it I make a mistake.
