When enrolling in the Apple developer program, it asks me to type my last name. Is the first one the only one required, or should I put both ?

I'm trying to get the array listaDeJugadores to be used in all my views. I am able to add a Player to it and its name and age. However, when I try to display it in the view called otherPage, it gives me an error, thread 1: Fatal error: Index out of range. I also want to be able to save the array listaDeJugadores with app Storage, however, I don't know if it's possible to use app Storage in this case. Any help will be appreciated! Thank you!. import SwiftUI class Todo: ObservableObject {   class Player {           var name = ""           var age = 0   }   @Published var listaDeJugadores: [Player] = [] } struct ContentView: View {          class Player {           var name = ""           var age = 0   }          @State var index = 0       @StateObject var lista = Todo()       @State var playerName = ""           @State var firstView = true   @State var secondView = false   @State var agePlayer = 0       var body: some View {           if firstView == true {       VStack {                   ZStack{           Color.pink                       TextField("Player name", text: $playerName)         }         .frame(width: 350, height: 50)         .cornerRadius(25)                   ZStack{           Color.pink           TextField("Player Age", value: $agePlayer, format: .number)         }         .frame(width: 350, height: 50)         .cornerRadius(25)                   Button(action: {                       lista.listaDeJugadores.append(Todo.Player())           lista.listaDeJugadores[index].name = playerName           lista.listaDeJugadores[index].age = agePlayer           playerName = ""           index += 1         }, label: {                       ZStack{             Color.black                           Text("Add")               .font(.title)               .foregroundColor(Color.white)                         }           .frame(width: 350, height: 50)           .cornerRadius(25)                     })         Button(action: {           firstView = false           secondView = true         }, label: {           ZStack{             Color.black                           Text("Done")               .font(.title)               .foregroundColor(Color.white)           }           .frame(width: 350, height: 50)           .cornerRadius(25)         })       }     } else if secondView == true {               otherPage()         .environmentObject(Todo())     }        }     } struct otherPage: View {       @EnvironmentObject var lista: Todo               var body: some View {     Text("\(lista.listaDeJugadores[0].name)")   } }

I'm trying to change the attribute of points by adding 1 every time the button is pressed, however, it does not change. How could I accomplish this?           class Person{           var name = ""     var points = 0   }   var Greg = Person()   var Jeo = Person()   var Humio = Person()       init(Greg: Person = Person(), Jeo: Person = Person(), Humio: Person = Person()) {     self.Greg = Greg     self.Jeo = Jeo     self.Humio = Humio           Greg.name = "Greg"     Jeo.name = "Jeo"     Humio.name = "Humio"   }           var body: some View {           var nombres:[Person] = [Greg, Jeo, Humio]          VStack {       ForEach(nombres, id: \.name){         names in                   ZStack{           Rectangle()            .frame(width: 200, height: 200)           VStack{             Text("\(names.points)")               .foregroundColor(Color.white)                           Button(action: {                               names.points += 1                             }, label: {                               Text(names.name)                             })                         }                     }                 }     }     .padding()   } }

I'm trying to create a new instance of my class "people" and add it to my list called listOfPeople. At the start, I ask how many people am I going to add. After I answer that, I add 1 to the variable "level" so I can continue as if it where a for loop. Now at level 1, I add the name and numberAssigned to the new instance which would supposedly go in listOfPeople in the position in which the variable counter is on. After I click the button with text "Add name" I would add another name and so on until I reach the numberOfpeople, so again, trying to simulate a for loop (I'm aware I have not added the logic for the textfield and button to add a new instance and stop when counter reaches the numberOfpeople). However, in this case, after I add the persons name and numberAssigned, it gives me the error in image number three. Which says "Thread 1: Fatal error: Index out of range." How could I make this work? I learned how to do this in c++ but I clearly do not know how to accomplish it in swiftui. Any help is appreciated! ;) I could make it work this way, the only problem is that if the user wants to add 1,000 people, I would have to have 1,000 variables pre-created, which I do not want, I want to be able to do it as a for-loop per se.

I want to display a random view, whether it's the firstScreen, secondSscreen or thirdScreen as seen in the pictures. I tried selecting a random element from my array but that does not seem to work. I hope you can help me! Thank you!

I have a tasks/notes app in the form of a list that when I add a task, I give it a title, for example “Groceries". I want to be able to click “groceries" and for there to appear a new list with new notes that would be such as beverages or food. Such notes would be added by the user.  Then in the main section if I want to add a new task or notes such as “Chores” ,when I click on chores it takes me to a new page in which the user can add chores.  However, right now I only know how to take it to the same view. So in other words, if i click on “groceries", I will see the same as if I click on “Chores”. In my app, it takes me to exampleView as you can see below. My app is made around core data, what I essentially want is for when I click a note such as groceries or chores, I can have a page in which I store new notes.  How can I make it so when I click on a note on the main page, it takes me to a new page? Any advice, tutorials, or anything helps. Thank You. ForEach(notesVM.notes, id: \.id){note in          NavigationLink(destination: exampleView()){          NotesCell(note: note)         } This is what I Have: This is what I Want:
