Introducing Zwitch: Revolutionizing the Sale and Switching of Pre-Owned Items in Sweden

At Digital Alfa, we are dedicated to helping our customers thrive in the digital era.

Our comprehensive portfolio of products and services, combined with a strong partner network, is tailored to optimize digital performance for medium-sized businesses, while also extending our support to start-ups and growing enterprises.

Today, we are excited to showcase our latest product, Zwitch, an innovative mobile application that is set to transform the way people exchange and sell old items in Sweden. Zwitch provides a seamless platform for users to connect, trade, and discover hidden treasures within their local communities.

We are thrilled to collaborate with Zwitch, a forward-thinking digital marketplace dedicated to revolutionizing the way we buy, sell, and trade fashion and home decor items. Zwitch empowers individuals to embrace circularity, offering a more enjoyable and sustainable approach to shopping. With Zwitch, you have the freedom to exchange* your unused belongings and give them a second chance. Have something at home that you no longer use? Simply place an ad on Zwitch, and with just a few clicks, wait for the right offer to come your way. And if you find something you want to buy, you can utilize your old items as a form of payment.

Here's how Zwitch works:

Download the Zwitch app for free from the App Store or Google Play Store, and explore our vast selection of unique items. Swipe through, scroll, or use the search function to find the perfect match.

Place an Offer:
When you come across an ad that catches your eye, it's time to make an offer. Bid using your own items, money, or a combination of both, providing flexibility and options.

Execute the Deal:
Engage in direct chat with the other party within the app. Discuss the details, arrange a meeting place, or even book transportation to finalize the transaction seamlessly.

Let's investigate the cutting-edge technologies that power the Zwitch app:

iOS App:

The Zwitch iOS app is built using Swift 5, with a minimum development version of 15.0. Employing the MVVM (Model-View-ViewModel) design pattern, our development team has created a robust architecture that enhances code modularity, maintainability, and testability. The MVVM pattern enables distinct layers within the app, reducing code complexity on the Views and ensuring clean, reusable, and maintainable code.
For dependency management, we leverage the Swift Package Manager (SPM), a versatile solution that offers faster resolution times. While SPM is the primary dependency manager, we continue to utilize CocoaPods for a specific third-party library that is not yet available on SPM.
To deliver seamless notifications, Zwitch utilizes the Apple Push Notification service, integrated with the Firebase Cloud Messaging client library. Additionally, the app's chat functionality is powered by Socket.IO, enabling real-time communication between users.

Android App:

The Zwitch Android app is built using Kotlin, the official language for Android application development since Google I/O 2017. Leveraging the Jetpack Compose toolkit, a modern UI framework developed by Google, our developers have created an efficient and visually stunning user interface. Jetpack Compose expedites testing processes and promotes code consistency through a unified codebase, minimizing the chances of errors. Zwitch Android app is compatible with devices running Android 7.0 (Nougat) and above, encompassing over 95.1% of Android devices worldwide.
Similar to the iOS app, Zwitch Android leverages the Firebase Cloud Messaging client library for notifications and employs Socket.IO for real-time chat functionality.
With Zwitch, we aim to revolutionize the way people buy, sell, and connect with pre-owned items in Sweden. Our robust technology stack ensures a seamless user experience, while our intuitive design guarantees an enjoyable interface for users of all levels of technical expertise.


At Digital Alfa, we leverage our expertise in technology to empower Zwitch, ensuring a seamless and user-friendly experience for both buyers and sellers. We invite you to explore Zwitch and witness the future of online second-hand shopping. Join us as we redefine the possibilities and empower individuals and communities to embrace sustainable consumption.
