adding buttons to the navigation bar in swiftui is a fundamental task that allows you to enhance user interaction in your app. swiftui provides a clean and declarative way to create user interfaces, including navigation bars. in this tutorial, we'll walk through the steps to add buttons to the navigation bar using swiftui.

step 1: setting up your swiftui project

first, create a new swiftui project in xcode:

1. open xcode and select "create a new xcode project."
2. choose "app" under the ios tab and click "next."
3. fill in the project details (product name, team, organization identifier, etc.) and ensure that "interface" is set to "swiftui."
4. click "next" and choose a location to save your project.

step 2: creating a basic navigation view

open `contentview.swift` and set up a basic `navigationview`. this serves as the container for your navigation bar and its items.

here’s how to do it:

```swift
import swiftui

struct contentview: view {
var body: some view {
navigationview {
vstack {
text("welcome to the app!")
.font(.largetitle)
.padding()
}
.navigationtitle("home") // set the title of the navigation bar
}
}
}
```

step 3: adding buttons to the navigation bar

swiftui allows you to add buttons to the navigation bar using the `.navigationbaritems` modifier. you can add buttons to the leading or trailing side of the navigation bar.

here’s an example of how to add buttons to both sides:

```swift
import swiftui

struct contentview: view {
var body: some view {
navigationview {
vstack {
text("welcome to the app!")
.font(.largetitle)
.padding()
}
.navigationtitle("home")
.navigationbaritems(leading: button(action: {
// action for leading button
print("leading button tapped!")
}) {
...
