We will get back to this file later.įirst, let’s write code for NavigationController.swift. Remove everything from the file called ViewController.swift. Window?.rootViewController = NavigationController(rootViewController: TabbarController()) Inside didFinishLaunchingWithOptions, simply copy and paste the lines below: window = UIWindow(frame: ) In the AppDelegate file, leave only didFinishLaunchingWithOptions, as you can remove all other methods. Somewhere inside your project, simply create a few new files -> TabbarController.swift, NavigationController.swift, PageViewController.swift. Simple ArchitectureĪs you already know by now, when you create a new app, you already have the Main ViewController class and Main.Storyboard.īefore we start designing, let’s first create all the necessary classes and files to make sure we have everything set up and running before we proceed to the UI part of the job. Press the Next button, and you’re ready to start building your swipeable tab bar. Uncheck: “Use Core Data,” “Include Unit Tests,” and “Include UI Tests.”.Organization Identifier: I named it com.toptal.

Note: If you do not have a developer account, you can run this on Simulator as well. In my case, I will use my own account for this. Team: If you want to run this application on a real device, you will have to have a developer account.Product Name: I named it SwipeableTabbar.Simply select “Single View App” and press Next.Īs you can see, the next screen will require you to provide some basic information:

To create a new project, open the Xcode application on your Mac and select “Create a new Xcode project,” then name your project, and finally choose the type of application to be created. The prerequisites needed for our project are quite basic: Xcode and Xcode build tools installed on your Mac. First of all, we need to create a new project. So, let’s dive into this feature and write an easy example of a swipeable tabbar for iOS. In these screenshots, you can see the first tab bar item is blue, then the user swipes to the right tab, which is yellow, and the last screen shows the third item is selected, so the whole page is displayed as yellow. In this case, you will need to instantiate those three view controllers and you will also need two placeholders/empty view controllers for the tabbar, to make tab bar items, change their state when the tab is pressed, or when the user wants to change the tab index programmatically.įor this, let’s dig into Xcode and write a couple of classes, just to see how these things work. Imagine that you have three tabbar items to be built, which automatically means you have three pages/controllers to be displayed per each tab item. Ultimately, I came up with a solution, though it proved somewhat tricky, as I’ll explain later. What if we group these two things together, handle page index whiling swiping or tapping on tabbar?” So, after some thinking and a lot of searching, I started implementing my own solution and I said to myself: “Hey, what if we use the page view controller for swipe, and native UITabBar. In case you are still interested, the lib can be found under this link. In other words, I found the library very easy to use, but buggy, which obviously outweighed its ease of use and tended to cause problems. Unfortunately, the library created a lot of issues while running the application, though it appeared as an elegant solution at first glance. Searching for An Easy UITabBar FixĪfter a fair amount of searching, I managed to find only one useful library on Github. One of these cases is UITabBar, where you do not have the ability to swipe between tabs, and you also do not have animations for switching between the tabs. Or is it?Īll of these basic components allow us to create basic structured UIs, but what happens if there is a need to go outside the box when an iOS developer needs to build some sort of behavior which is not supported in the SDK by default? Buttons, containers, navigations, tabbed layouts, you name it-almost everything you’ll ever need is there. As you know, Apple’s iOS SDK contains a myriad of built-in UI components.
