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)
}
