Can't refresh view after changing published variable - ios

Question

I have three files: ContentView (main file), HomeView, ConfigView
I wish I could change one string that is located in HomeView by pressing a button in ConfigView, but I can't do it.
Edit: I realized the problem is because I'm storing objects inside the DadosTimes class. I tried to store a simple string and it worked. How can I make it work even using an object?
ContentView file:
import SwiftUI
extension View {
func inExpandingRectangle() -> some View {
ZStack {
Rectangle()
.fill(Color.clear)
self
}
}
}
//Here i have a declaration for a custom button
class Equipe {
var nome: String
var pontos: Int
var vitorias: Int
init(nome: String) {
self.nome = nome
self.pontos = 0
self.vitorias = 0
}
func addPontos(_qtd: Int){
self.pontos += _qtd
}
}
struct ContentView: View {
#EnvironmentObject var InfoJogo: DadosTimes
var body: some View {
TabView{
HomeView()
.tabItem({
Image(systemName: "house")
Text("Placar")
})
ConfigView()
.tabItem({
Image(systemName: "gear")
Text("Configurações")
})
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
class DadosTimes: ObservableObject{
#Published var time1 = Equipe(nome: "Nós")
#Published var time2 = Equipe(nome: "Eles")
}
HomeView file:
import SwiftUI
struct HomeView: View {
#EnvironmentObject var InfoJogo: DadosTimes
var body: some View {
ZStack{
Color("FundoVerde")
.ignoresSafeArea()
VStack {
HStack{
VStack(spacing: 0){
TextField("", text: $InfoJogo.time1.nome)
.foregroundColor(Color.black)
.font(.system(size: 50))
Text(String(InfoJogo.time1.pontos))
.foregroundColor(Color.black)
.font(.system(size: 85))
Text(String(InfoJogo.time1.vitorias) + " Vitórias")
.foregroundColor(Color(.darkGray))
.font(.system(size: 17))
BotaoPrimario(title: "+", size: 50, action: {
InfoJogo.time1.addPontos(_qtd: 1)
verificaGanhador()
})
}
.inExpandingRectangle()
.fixedSize(horizontal: false, vertical: true)
VStack(spacing: 0){
Text(InfoJogo.time2.nome)
.foregroundColor(Color.black)
.font(.system(size: 50))
Text(String(InfoJogo.time2.pontos))
.foregroundColor(Color.black)
.font(.system(size: 85))
Text(String(InfoJogo.time2.vitorias) + " Vitórias")
.foregroundColor(Color(.darkGray))
.font(.system(size: 17))
BotaoPrimario(title: "+", size: 50, action: {
InfoJogo.time2.addPontos(_qtd: 1)
verificaGanhador()
})
}
.inExpandingRectangle()
.fixedSize(horizontal: false, vertical: true)
}
.padding(.vertical, 50)
.frame(maxWidth: .infinity)
.background(Rectangle()
.foregroundColor(.white)
.cornerRadius(15)
.shadow(radius: 15)
)
}
.padding(.horizontal, 20)
}
}
}
struct HomeView_Previews: PreviewProvider {
static var previews: some View {
HomeView()
}
}
ConfigView file
import SwiftUI
struct ConfigView: View {
#EnvironmentObject var InfoJogo: DadosTimes
var body: some View {
ZStack{
Color("FundoVerde")
.ignoresSafeArea()
VStack{
Button("Mudar Nome"){
InfoJogo.time1.nome = "oiii"
}
TextField("", text: $InfoJogo.time1.nome)
}
}
}
}
struct ConfigView_Previews: PreviewProvider {
static var previews: some View {
ConfigView()
}
}
I have already logged in console the InfoJogo.time1.nome variable and it changes in the memory. It's not updating on the screen. What should I do? I've already looked for help everywhere but I couldn't find the solution.
Sorry if it's a basic question, but I've started learning swift yesterday ;)

#Paulw11 provided a perfect description why the change doesn't trigger an update.
What you can do is trigger the update manually with objectWillChange.send().
In your button action do:
BotaoPrimario(title: "+", size: 50, action: {
infoJogo.objectWillChange.send() // here
infoJogo.time2.addPontos(_qtd: 1)
verificaGanhador()
})
