There are many situations when you'd like to add a header and footer to a UICollectionView component, in Swift. Regardless whether it's a simple title or a more advanced view, UICollectionView supports headers and footers out of the box, without too much boilerplate code.

WWDC 2020 has ended. As usually, Apple introduced a lot of new things during the conference. They include the transition from Intel chips to ARMs, new iMacs, new OSs. One of the most expected announcements also happened: SwiftUI 2.0. Let's discover if there is anything new in this version of SwiftUI, which starts to mature nicely.

In this iOS tutorial, we are going to learn how to implement a tab bar in SwiftUI by leveraging TabView. Feel free to skip directly to the source code (at the bottom of the page), if you already know what you're doing.

Hello, welcome back to our SwiftUI tutorials series. In this article, we are going to learn how to use the photo camera and library picker in SwiftUI to take photos within our iOS apps – a feature that nearly every mobile application needs nowadays, especially with the latest iPhone release, that has 3 cameras!

In this article we will talk about @EnvironmentObject in SwiftUI and how to use it to handle certain state management situations within our iOS applications.

Combine framework is a new framework that Apple unveiled in this year’s WWDC. Combine helps developers work with synchronous and asynchronous tasks. Let’s take the example of a “Sign Up” form.

When you start developing with SwiftUI, you will reach certain points during development where you would like to use some APIs from UIKit. In order to integrate UIKit with SwiftUI, you can use one of two protocols – UIViewControllerRepresentable and UIViewRepresentable. We will soon be migrating all of our iPhone app templates (currently running on UIKit) to SwiftUI, so having them use both UIKit and SwiftUI as a transition state during migration will be a huge advantage in order to not block our customers who are willing to take a stab at SwiftUI early on (even if we don’t recommend it yet!).

SwiftUI is a newly released framework to help iOS developers build user interfaces across all Apple platforms with the power of Swift. SwiftUI has been launched at WWDC 2019 and has been increasing in popularity exponentially ever since. SwiftUI addresses the major pain points that iOS engineers were facing with building interfaces, and for these reasons, SwiftUI is the future of front-end development on iOS. We are making a quick introduction to SwiftUI to highlight its simplistic yet powerful paradigm.

Any business that is developing an e-commerce application will certainly consider Stripe when it comes to processing payments. Stripe provides an awesome library that instantly enables users to use their mobile phones for online payments. Stripe SDK has increased in popularity tremendously in the last 5 years, and it represents our preferred payment processor in our app templates. Integrating Stripe Firebase in iOS is extremely powerful, but quite challenging, which is the reason why we have written this tutorial.

If you’re an iOS developer with advanced skills who has gone through a lot of iOS projects, you will surely know that choosing a suitable design pattern is extremely important. It helps your project run smoothly and become more readable, flexible and reusable. In more than 20 Mobile App Templates, we have carefully considered all the most popular iOS design patterns.

In the past two years, we’ve built more than 20 fully functional iOS Templates. As you can image, code reusability is one of the top priorities for us, when it comes to creating a Swift app. In order to reuse as much code as possible, we are focusing on modularizing our codebase as much as possible, by leveraging various design patterns, compatible with Swift. In this Swift tutorial, we are taking a look at the Facade Design Pattern. Let’s understand what it is, what kind of architectural approach it takes and let’s also see a code snippet implementing it in Swift.

Adding a map to an iOS app is a widely spread feature. Maps make mobile apps more interactive and improve the user experience tremendously. In our mobile app templates, we integrated maps in several apps, such as in the Store Locator, Classifieds App, or Real Estate app. In this MapKit tutorial, we are describing our experience of working with MapKit to help you learn how to add maps to your iOS app in Swift.
