This extension lets us add the .if modifier to our Views and will only apply the modifiers we add if the condition is met.

SwiftUI Conditional

With this extension, we can add the .if() modifier to our View!

Example

struct ContentView: View {
    @State private var shouldAddShadow: Bool = true

    var body: some View {
        Text("Hello, world!")
            .if(shouldAddShadow) { view in
                view.shadow(color: .black, radius: 10, x: 0.0, y: 0.0)
            }
    }
}

SwiftUI+Conditional.swift

import SwiftUI


// [Conditional modifier](https://designcode.io/swiftui-handbook-conditional-modifier)
extension View {
    
    @ViewBuilder func `if`<Content: View>(_ condition: Bool, then transform: (Self) -> Content) -> some View {
        if condition {
            transform(self)
        } else {
            self
        }
    }
    
    @ViewBuilder func `if`<Content: View>(_ condition: Bool, then transformThen: (Self) -> Content, else transformElse: (Self) -> Content ) -> some View {
        if condition {
            transformThen(self)
        } else {
            transformElse(self)
        }
    }
