ViewCondition – systamatic coding viewcontroller

July 15, 2025

✨ Super sweet syntactic sugar for SwiftUI.View initializers.

At a Glance


                                              
                                                struct BorderTextView: View {

var color: Color?
@ViewBuilder

var body: some View {

Text(“Hello”)

.if(let: color) {

$0.border($1)

}

}

}

This is equivalent to:


                                              
                                                struct BorderTextView: View {

var color: Color?
@ViewBuilder

var body: some View {

let text = Text(“Hello”)

if let color = color {

text.border(color) // border doesn’t allow optional

} else {

text

}

}

}

Operators

if let


                                              
                                                let color: Color?

Text(“Hello”)

.if(let: color) {

$0.border($1)

}

if


                                              
                                                let text = “”

Text(“Hello”)

.if(text == “Hello”) {

$0.bold()

}

ifNot


                                              
                                                let text = “”

Text(“Hello”)

.ifNot(text == “Hello”) {

$0.bold()

}

then


                                              
                                                let text = “”

Text(“Hello”)

.then {

if text == “Hello” {

$0.bold()

} else {

$0.italic()

}

}

⚠️ Becareful

If you don’t return view in else, the view may not come out.
