extension Date: RawRepresentable { public var rawValue: String { self.timeIntervalSinceReferenceDate.description } public init?(rawValue: String) { self = Date(timeIntervalSinceReferenceDate: Double(rawValue) ?? 0.0) } } This one works Thank you!

Your code makes CloudKit work but stops the widget extension from connecting to the CoreData Database. Thank you for your time.

I don't think it's working. It still syncs the data across devices just if I close and reopen the app. I had also tried using a timer, to call the readData function every second, but it creates several bugs in the app.

The problem is not the onTapGesture (the onTapGesture is also a placeholder), the problem is that valori has fewer elements than valoriAsseX, I want that if valori[I] doesn't exist it becomes 0. Don't look at the onTapGesture, it's not a problem

The ** values ** array is just a placeholder for now, it can be empty or have N elements, I just want to assign 0 to values[i] when it doesn't exists, but when I try it it crashes anyway

That is what I wanted, thank you

Can you describe how you want to use it more specifically? I want to trim it 50% from top to bottom not from right to left, at the end I want it trimmed from the center to the top.

It is not the right description of trim(from:to:). Ok, thanks for the correction you may need something other than trim(from:to:). What would you use or how would you do it?

Text( "\(networkController.users.main ?? Main(temp: 0).temp)") Gives some errors: Cannot convert value of type 'Float' to expected argument type 'Main' Instance method 'appendInterpolation' requires that 'Main' conform to '_FormatSpecifiable' But yes, (this: Text( "\(networkController.users.main ?? Main(temp: 0).temp)")), this is what I want to do.

Actually this is not working: ForEach(networkController.users, id: \.self){ user in I thought it was right, that's why I checked it

Did you get some different results than this? No

Try 0.1 + 0.2, you won't get the right result (at least for me)

So, when I press the decimal point button it should add a decimal point, what happens is that when I press the decimal point it doesn't consider the numbers that I write after the decimal point. Sorry for my inaccuracy, I'm still learning and thank you very much

Sorry, I didn't make myself clear I made a calculator and when I tap the numbers, they don't append to each other, how do I solve it This is what I am doing: // // ContentView.swift // Calcolatrice // // Created by Jad Taljabini on 26/03/21. // import SwiftUI import Combine enum Nums: String{ case uno = "1" case due = "2" case tre = "3" case quattro = "4" case cinque = "5" case sei = "6" case sette = "7" case otto = "8" case nove = "9" case zero = "0" case moltiplicazione = "X" case divisione = "/" case somma = "+" case meno = "-" case uguale = "=" case AC = "AC" case piùMeno = "±" case percentuale = "%" case virgola = "." case niente = "" } struct ContentView: View { var numeri: [[Nums]] = [ [Nums.AC, Nums.piùMeno, Nums.percentuale, Nums.divisione], [Nums.sette, Nums.otto, Nums.nove, Nums.moltiplicazione], [Nums.quattro, Nums.cinque, Nums.sei, Nums.meno], [Nums.uno, Nums.due, Nums.tre, Nums.somma], [Nums.zero, Nums.niente, Nums.virgola, Nums.uguale] ] private var gridItemLayout = [GridItem(.flexible()), GridItem(.flexible()), GridItem(.flexible()), GridItem(.flexible())] @State var res: Double = 0 @State var previousVar: Double = 0 let timer = Timer.publish(every: 0.001, on: .main, in: .common).autoconnect() @State var con: Int = 0 @State var final: Double = 0 @State var operat = Nums(rawValue: "") var body: some View { VStack{ Spacer() HStack{ Spacer() Text("\(res, specifier: "%.2f")") .font(.system(size: 50)) .bold() .padding() } Spacer() LazyVGrid(columns: gridItemLayout, content: { ForEach(0..5){ i in ForEach(0..4){ j in RoundedRectangle(cornerRadius: 35.0) .foregroundColor(.orange) .frame(width: 80, height: 80, alignment: .center) .overlay( Text("\(numeri[i][j].rawValue)") .font(.largeTitle) .foregroundColor(.black) ).onTapGesture { switch numeri[i][j] { case Nums.AC: operat = Nums.AC; res = 0 case Nums.uguale: operat = Nums.uguale; res = final case Nums.somma: operat = Nums.somma; previousVar = res; res = 0; con = 0 case Nums.meno: operat = Nums.meno; previousVar = res; res = 0 con = 0 case Nums.divisione: operat = Nums.divisione; previousVar = res; res = 0; con = 0 case Nums.moltiplicazione: operat = Nums.moltiplicazione; previousVar = res; res = 0; con = 0 case Nums.percentuale: operat = Nums.percentuale; res = res / 100 case Nums.piùMeno: operat = Nums.piùMeno; res = res * -1; con = 0 case Nums.virgola: operat = Nums.virgola; res = Double(String(res) + ".") ?? 0 default: res = Double(numeri[i][j].rawValue) ?? 0 con += 1 } } } } }).onReceive(timer) { _ in if con != 0 { if operat == Nums.divisione{ final = previousVar / res } else if operat == Nums.meno{ final = previousVar - res } else if operat == Nums.moltiplicazione{ final = previousVar * res } else if operat == Nums.somma{ final = previousVar + res } } } }.padding(2) } } At line 115 I am making res equal a number, what I want to do is to append that number to res Thank you
