@ViewBuilder with custom functions to create reusable conditional view logic. Instead of repeating if-else statements across views, extract them into computed properties or functions marked with @ViewBuilder for cleaner, more maintainable code.Extract complex conditional view logic into separate ViewBuilder computed properties or functions instead of cluttering the main body. This separates concerns and makes the view structure more readable.
struct ContentView: View {
let isLoggedIn: Bool
let hasNotifications: Bool
var body: some View {
VStack {
headerContent
mainContent
}
}
@ViewBuilder
private var headerContent: some View {
if isLoggedIn {
HStack {
Text("Welcome back!")
Spacer()
if hasNotifications {
Badge("3")
}
}
} else {
Button("Sign In") {
// Handle sign in
}
}
}
@ViewBuilder
private var mainContent: some View {
if isLoggedIn {
DashboardView()
} else {
OnboardingView()
}
}
}This approach improves code organization, makes views easier to test and debug, enables better reusability across components, and keeps the main body focused on layout structure rather than conditional logic details.
