Unsafe Binding Access on SwiftUI

It’s not always safe to access a Binding within a callback that isn’t part of SwiftUI’s event system. An example is illustrated in the following sample code:

extension Notification.Name {
    static let event = Notification.Name("event")
}

Use var in struct in Swift

TL;DR: Use var for properties in struct as long as it serves as a nominal tuple. In most cases, there is no obvious benefit to using let for struct properties.

Simple Example

Let's start with a simple example:

struct MyStruct {

import SwiftUI

struct ContentView: View {
    var body: some View {
        VStack {
            TextSampleView(style: .foreground)
            TextSampleView(style: .mint)
            TextSampleView(style: linearGradient)
        }
        .font(.largeTitle)

import SwiftUI

struct ContentView: View {
    @State var rating: Double = 0

    var body: some View {
        HStack(spacing: 18) {
            Button(
                action: { withAnimation { rating -= 1 } },
                label: { Image(systemName: "minus.circle") }
