So I just added charts to my app and I am having some problems. My app is randomly crashing and I cannot repro the issue no matter what I do. I have tried everything from trying this on a real device to logging in as the users who Crashlytics initially says were affected by the error to attempting to create new users and sign them in. Nothing I do causes the app to crash. I know this is a lot to look through but any advice would be very greatly appreciated. Thank you in advance for any help. This is the code: struct MultiLineChartView : UIViewRepresentable {   var entries1 : [ChartDataEntry]   var entries2 : [ChartDataEntry]   var months: [String]       func makeUIView(context: Context) -> LineChartView {     let chart = LineChartView()           return createChart(chart: chart)   }       func updateUIView(_ uiView: LineChartView, context: Context) {     uiView.data = addData()   }       func createChart(chart: LineChartView) -> LineChartView{     let numberFormatter = NumberFormatter()     numberFormatter.generatesDecimalNumbers = false     chart.leftAxis.valueFormatter = DefaultAxisValueFormatter.init(formatter: numberFormatter)     chart.chartDescription?.enabled = false     chart.xAxis.drawGridLinesEnabled = false     chart.xAxis.drawLabelsEnabled = true     chart.xAxis.drawAxisLineEnabled = false     chart.xAxis.labelPosition = .bottom     chart.rightAxis.enabled = false     chart.leftAxis.enabled = false     chart.drawBordersEnabled = false     chart.xAxis.forceLabelsEnabled = false     chart.xAxis.granularityEnabled = true     chart.xAxis.granularity = 1     chart.xAxis.valueFormatter = CustomChartFormatter(days: months, entries1: entries1)     chart.doubleTapToZoomEnabled = false     chart.dragEnabled = true     chart.noDataTextAlignment = .center     chart.noDataText = "Not enough data.

Hey everyone, When I try to create a Core ML Model in the Core ML Model Collection Dashboard located at: https://ml.developer.apple.com/core-ml/teams/XXXXX/model-collections It keeps giving me an error that says: "One of the fields was invalid." If I go into the developer console in Chrome to look at the exact error message coming back from the API I see that it says: detailedMessage: "errorResponse(clientCode: "noerror", serverCode: "unknown", operation: "SaveZone", message: "Custom Zone limit exceeded", retryAfterSeconds: "0", cloudDbErrorName: "SIZE_LIMIT_EXCEEDED", additionalInfo: "["operationType": "ZoneSave"]", stackTrace: "")" Has anyone else had this problem? I am new to Core ML and have never created a model before so maybe Im missing something.
