Use if condition on SwiftUIView without breaking method chaining

View+Extensions.swift

extension View {
    @ViewBuilder
    func `if`<TrueContent: View, FalseContent: View>(
        _ condition: Bool,
        @ViewBuilder _ trueTransform: (Self) -> TrueContent,
        @ViewBuilder else falseTransform: (Self) -> FalseContent
    ) -> some View {
        if condition {
            trueTransform(self)
        } else {
            falseTransform(self)
        }
    } 
}

// Usage: -
struct ContentView: View {
    let isSelected: Bool = true

    var body: some View {
        Text("Hello, world!")
            .if(isSelected) {
                $0.foregroundColor(.primary)
            } else: {
                $0.foregroundColor(.secondary)
            }
    }
}
