Swiftui navigation bar background

Welcome back to a new tutorial of our SwiftUI series. In this tutorial, we are going to learn how to implement a navigation drawer in SwiftUI, also know as side menu, side bar menu or hamburger menu. If you have ever worked with it in UIKit, you will understand its nature thoroughly. We will simply create a ViewController and assign it as a quick navigator. Before getting into it, we would like to make sure that you do not miss any of our previous articles related to SwiftUI — they are extremely clear, concise and helpful.

In this first step, we are going to create two things. The first one is the content of the navigation drawer. This will usually be a list of screens that users can navigate to. You could see an example in the image below. This is one of our templates where we implemented the navigation drawer. The second part is the underlying padding. Its responsibility is to take care of tasks such as frames, transitions, opacities, borders, etc. This block of code looks quite wordy but it is relatively simple.

It declares a navigation bar with the title and a left item which is a button. Tapping on that will trigger our drawer. Now, this is the most important part — how to emit a signal to show or hide the navigation drawer. Then, we will pass the latest value into the NavigationDrawer. And once the NavigationDrawer receives the signal, it will update its frame correspondingly. In this tutorial, you learned the basic concepts needed to implement a navigation drawer in SwiftUI.

If you have any questions or comments as you work through this SwiftUI tutorial, feel free to comment below or ask us here. Thanks so much and b e sure to stay tuned for more tutorials!I started to use it for a personal project to understand its potential.

In the last week I started to develop a new personal project: a new iOS mobile app that I will show you in the following months. As a consequence of the fact that this was a greenfield project I decided to use SwiftUI to develop all the User Interface and Combine for data binging. These frameworks are the Apple implementation of reactive programming combine and declarative user interface programming SwiftUI. In this post we will focus on SwiftUI we will see combine in another post later.

In this post I will show you how I created a custom tab bar with the ability to open a modal from a tab bar item like some major apps, e. Instagram and a customized navigation where the TabBar is shown only on the first level of navigation.

Below you can find a video that shows the final result. In the custom tab bar there will be three element, but only two are real tabs as you see from the video above the one in the middle is modal. The main view MainView contains 2 variable fields:. The body of the view is composed by a NavigationView that contains a VStack with main components of the custom tab bar implementation:.

There are also some style customization like forcing the navigationViewStyle to StackNavigationViewStylein order to avoid to see a blank screen on iPad because the NavigationView on iPad is a split view by default. Last but not least, there is a sheet defined to show a ScreenModal view as a modal whenever the state variable showModal changes.

This view is really simple: it shows a specific screen based on the value of its currentView. As you may already noticed, currentView is a not a state variable. It is annotated with the property wrapper Binding. What does it mean?

The Binding property wrapper lets us declare that one value actually comes from elsewhere, and should be shared in both places. This basically means that this variable will be updated as soon as the variable passed at construction time for this view will be update, and the view will be update consequently by changing the screen shown. Also this view contains two Binding variables:. The implementation of TabBarItem is simple. It contains the styling for the tab bar item.

The important thing to notice is here is the onTapGesture modifier. Whenever a user taps on it the Binding currentView variable will be updated and so also the State variable currentView in the MainView and consequently also the CurrentScreen view will be update.

It contains the style for the custom TabBar item and it attach the action to show the modal to the view with the onTapGestureModifier. Screen1Screen2 and ScreenModal are full screen VStack view that defined the content for each screen. The important part is the definition of the title on Screen1 and Screen2 to modify the navigation bar using the navigationBarTitle modifier.

As you remember in the MainView we defined a NavigationView as container of the custom TabBar with the current content.

This let us keep the TabBar only on the first level of navigation and it when the user enters in the details screen. You can find all the code shown in this post in this Github repo. If you already used powerful declarative framework like React or React Native you will feel at home seems like a copy of each other.

Stay tuned for other post about SwiftUI and Combine soon. There are a lot of dependency injection framework in the open source swift world with really cool features like object graph, persistence etc. But what if all you need is a lightweight dependencies container?

In this post I will show you how to create it by leveraging the Metatype Type, Generics, the Hashable protocol and the Equatable protocol. React native 0. PWA offer great native alike offline capabilities. But what about tracking? Home Blog About Me. Creative Stuff.Most part of the navigation bar can be customized using the appearance protocol, such as the title, background and the navigation bar items. In this tutorial a navigation view containing a list will be displayed and customized.

In the canvas, click Resume to display the preview. In the Project navigator, click to select ContentView. Change the code inside the ContentView. The people struct will be used as the model for the items in the list.

A list is displayed, when a row is selected the detail view is displayed containing the current selected name. Two navigation bar items are declared containing a system image each with a custom color. The detailview struct will display the current selected name. To apply more customization to the navigation bar, the appearance protocol can be used.

Add the init method to the ContentView struct. The background color of the navigation bar is set to yellow. Go to the preview pane and click the live preview button. The Navigation Bar in the content view is customized. Tutorials iOS Development Tutorials. The navigation bar title is displayed The detailview struct will display the current selected name The navigation bar style is set to. Click a name in the list to view the detail view.

SwiftUI lets you ignore Interface Builder and storyboards without having to write detailed step-by-step instructions for laying out your UI. And live preview means you rarely need to launch the simulator. SwiftUI enables you to do declarative app development: You declare both how you want the views in your UI to look and also what data they depend on.

It recomputes the view and all its children, then renders what has changed. There are lots of primitive views like Text and Colorwhich you can use as basic building blocks for your custom views. Open ContentView. The first tab lists primitive views for layout and control, plus Other Views and Paints.

The second tab lists modifiers for layout, effects, text, events and other purposes like presentation, environment and accessibility. A modifier is a method that creates a new view from the existing view. You can chain modifiers like a pipeline to customize any view. SwiftUI encourages you to create small reusable views, then customize them with modifiers for the specific context where you use them. Start by creating a basic list for the master view of your master-detail app. You create a static array of strings, and you display them in a List view, which iterates over the array, displaying whatever you specify for each item.

And the result looks just like a UITableView! Make sure your canvas is open, then refresh the preview click Resume or press Option-Command-P :. How easy was that? The parameters of List are the array, which is obvious, and idwhich is less obvious. Now take a closer look at how id works: Add another "statue" to disciplines :. Refresh the preview: all four items appear.

A breakpoint might shed some light. The first time you run Debug Preview, it will take a while to load everything. Eventually, execution stops at your breakpoint, and the Variables View displays discipline :. Now, the next time you click the Continue button, what do you think will happen? Is this the fourth list item? Then one final Continue displays the list of four items. So List does see only three unique items.

This is like embedding a view controller in a navigation controller: You can now access all the navigation things, like the navigation bar title. You can declare more than one view in a NavigationViewand each can have its own. You get a large title by default. So first, create your DetailView. For now, just declare it in ContentView.

This has a single property and, like any Swift struct, it has a default initializer — in this case, DetailView discipline: String.

The view is just the String itself, presented in a Text view.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
