With every release of Xcode, Apple provides us with extremely useful improvements and new features. And as always, from Xcode 11.4 (beta version – up until the publish date of this article), we get another piece of good news from them. That is we can simulate push notifications on the iOS simulator. Finally! Yes, you're not mistaken, it's time to say goodbye to the annoyance of testing on physical devices whenever we want to implement and test push notifications.

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.

Dating apps exploded in popularity in the last couple of years. Mobile startups like Tinder or Grindr created a revolution in online dating. They not only revolutionized the dating front, but they set new trends on the mobile design front, through UI features such as the well known Tinder Swipe. Mobile app development cost got much cheaper in the last years. In this article, we analyze how much does it cost to make an app like Tinder or Grindr. There are multiple approaches, so let’s jump right into it.

The App Store is a giant app market created by Apple. Every day, hundreds of iOS applications are being published to the App Store. To keep a high bar on the quality of mobile applications, Apple has a system in place to review iOS apps very carefully. In this article, we are publishing a Complete App Store Submission Checklist, that can be reviewed by entrepreneurs and developers, before submitting to the iOS App Store.

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.

In today’s article, we are taking a closer look at what reactive programming in Swift is all about and how we can use this design pattern in iOS apps by leveraging RxSwift. At Instamobile, we are building a ton of cool iOS apps, so we always consider using the most appropriate design patterns to build highly modularized iOS Starter Kits.
