Sealed interfaces were just introduced in Kotlin 1.5 and are a very powerful new feature. But with great power comes great responsibility, so we need to learn when to use and when to not use this newly achieved power. In order to...

When creating a library, we usually strive to support all commonly used package managers. For iOS libraries, the most popular ones are Cocoapods, the Swift Package Manager (SPM), and Carthage.Different package managers have different ways...

When your iOS (or macOS) app needs to read data from a nearby Bluetooth device – how do you decode the data included in the BLE characteristics? At QuickBird Medical, we often work with medical devices. Our apps need to safely read health...

Search is a crucial feature for many apps. Flutter already offers some search bar widgets to go with, but as soon as you want to use designs for platforms other than Material (like Cupertino), you run into problems. So what’s the best way...

Large, complex apps rely on a robust, yet flexible app architecture. In this article, we’ll show you how to accomplish this goal and how to handle navigation and deep-linking with SwiftUI. With more and more people building...

When working with any communication or storage medium such as Bluetooth, wi-fi (and even wired networks) or disk storage, data can get corrupted. In such cases, we need to make sure that the data we receive (or read) is the same data that...

When developing iOS apps with UIKit, many developers have used the Coordinator pattern to abstract away the connections between individual view components. This increases the reusability of view components (such as view controllers),...

It’s rare that you juggle with bits and bytes in Swift because of its neat static type system. Most of the time, you don’t care what’s under the hood – you just work with classes, structs, and enums or primitive types...

When working with any communication or storage medium such as Bluetooth, wi-fi (and even wired networks) or disk storage, data can get corrupted. In such cases, we need to make sure that the data we receive (or read) is the same data that...

The cool thing about programming is that there is an absolute truth in every Bit: It’s either black or white, 1 or 0, true or false. In theory. But whenever you transmit data or store it somewhere on a physical drive, it can get...

In this article, we're going to build some MVI View Models on Android and explore how we can test them efficiently. The post Testing MVI View Models on Android appeared first on QuickBird Studios Blog.

We love Swift as a lean and intuitive programming language and recently, SwiftUI made our hearts beat faster for providing us with great tools to create amazing user experiences with very little, simple code. But with the introduction of...

What do you prefer: creating user interfaces visually or in code? This question has split the Apple developer community for years. Could this year’s WWDC finally mark the end of that? Last year, Apple made a huge step forward in UI...

MVI is a common architecture pattern to design your Android apps. There are lots of articles out there about MVI but most of them use RxJava. In this article we instead use Kotlin Coroutines & the Kotlin Flow API to implement an MVI...

Facing the Corona virus, many companies around the globe need to switch to remote work right now. While this is required by law in some places, we see it as our social obligation towards society. Doing home office for a couple of weeks or...

“Your code sucks!” – It’s usually not what the reviewer said, but that’s how we perceive it sometimes when our code is being reviewed. We feel challenged or even provoked. Our pride is at stake! So we either begin lengthy discussions...

In this article, we collected best practices to keep your users’ data secure in Android Apps. We are going to talk about how you can implement mobile app security for storing data, communicate between client and server and other aspects...

Mobile apps often deal with really private and sensitive user data like personal health information or banking information. Losing data or getting hacked, therefore, can have huge consequences. There is no bigger nightmare for any app...

With SwiftUI and Xcode 11 released just recently, we decided to investigate different app architectures that can be used with SwiftUI. We're going to look into a rather simple Model-View architecture, the Redux architecture pattern and the...

Many people criticized Dart because it was missing features like Extensions that programmers knew and love from other programming languages like C#, Swift or Kotlin. This Year at Google IO, the Dart team announced three new features. One...
