Force Update Mechanism

Implementing a basic force update mechanism in your SwiftUI app

Posted on September 29, 2023

In the ever-evolving landscape of mobile applications, keeping your app up-to-date is not just a best practice—it’s often a necessity. Whether it’s a critical security patch, a new feature release, or a simple bug fix, ensuring that your users are running the latest version of your app can be crucial for both user experience and security. This is where the concept of “Force Update” comes into play. A Force Update mechanism allows you to compel users to update the app to continue using it.

SwiftUI: Using a Repository as the single source of truth

Posted on April 30, 2023

Introduction: In a SwiftUI app, it is important to have a single source of truth for the app’s data. This ensures that all views and components that rely on the data are always in sync, preventing inconsistencies and bugs. One way to achieve this is by using a Repository object to manage the app’s data. In this article, we’ll explore how to use a Repository object to hold the single source of truth for a SwiftUI app, based on the code in this repository: https://github.com/mdb1/SwiftUI-RepositoryExample [Read More]
