1 Specifying a minimum width for the image’s frame will help overcome the issue of the image bounds going outside of the frame (remember, this happens because child views can take up as much space, even if the size goes beyond what the parent is offering). Then, add this code: import SwiftUI struct CustomTabBarItem: View // Preview hasn't changed. First, create a new SwiftUI View file and name it CustomTabBarItem.swift. Now that you have a simple Tab Bar Item, refactor it into its own View and add more tab items. You will find links to commits in this repository, that also contains the final product. A SwiftUI TabView is a SwiftUI component that allows us. The information in all 3 parts of these articles are still relevant however, so if you’d like to learn more about SwiftUI, read on! In this video, well discuss how we can create our own custom tab bar in SwiftUI by using Tab View. These provide an easy to update appearances and share common settings. At right around 4:30, they talk about these new UITabBarAppearance and UINavigationBarAppearance APIs. The following example creates a tab view with three tabs, each presenting a custom child view.

In Part 1, we’ll be setting up the custom tab bar project, without using view preferences, and just one simple usage of GeometryReader.If you haven’t been exposed to these concepts, I strongly recommend you check out Javier’s article on GeometryReader and the three articles that follow that one. You could use UITabBarController from UIKit, but then you lose the ability to access the navigation controller through SwiftUI. I chose a custom tab bar for our example because in a previous piece I wrote about SwiftUI’s TabView bugs, which stop it being useful beyond five tabs. We’ll be doing this as we implement a custom tab bar. In this five-part series, we’ll be walking through GeometryReader and a new concept in SwiftUI: view preferences.
