Seems that xcode has trouble lint/type checking inside closures. I was building the below view and made some typos, then my macbook started overheating due to xcode and could not get proper lint errors. struct ContentView: View {   let astronauts: [Astronaut] = Bundle.main.decode("astronauts.json")   let missions: [Mission] = Bundle.main.decode("missions.json")   var body: some View {     NavigationView {       List(missions) { mission in         NavigationLink(           destination: Text("Detail View"),           label: {             Image(mission.image)               .resizable()               .scaledToFit()               .methodThatDoesntExit()               .frame(width: 44, height: 44)             VStack(alignment: .leading) {               Text(mission.displayName)                 .font(.headline)               Text(mission.formattedLaunchDate)             }           })       }       .navigationTitle("Moonshot")     }   } } This will will throw a generic error instead of telling me .methodThatDoesntExit() doesn't exist. The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions One solution is to create a separate item view and provide that in the closure, then everything works as expected.
