iOS Data Persistence: A Guide for Swift Developers

The term ‘data persistence’ refers to data that remains available, even when the program that created it is idle, sleeping or unable to open. In many cases, our iOS apps need to provide support around the clock, so we need our data to be ‘always on’ – even when the apps themselves are not.

Integrating iOS Push Notifications Using Swift

Push notifications play a vital role in user engagement and retention, keeping users up to date and creating a sense of FOMO that leads to purchases. And in iOS, we get the added benefit of Apple’s Push Notification Service (APNs). which acts as a middleman between the app server and the user’s device, facilitating the delivery of push notifications even if the app is not active or the user is checking another of their apps.

iOS In-App Purchases: A Comprehensive Guide for Swift Developers

iOS in-app purchases, or IAPs, allow developers to offer content, services, and features within their iOS apps for users to purchase. This can provide a significant revenue stream for developers, while enabling users to enhance their experience or access premium content and services. An iOS in app purchase can be a good alternative to paid applications, as an iO app developer can offer the app for free and monetize it via app purchasing options.

Exploring Swift Extensions: Strategies for Efficient iOS Code

If you’ve done any work on iOS apps these last few years, you’ll know how concise and expressive the Swift language can be. And you may well have benefited from Swift extensions, a powerful mechanism that lets you, the developer, extend both your functionality and Swift’s, by extending any Objects and Structures you need. However, the variety and versatility of extensions does present teething challenges.

The iOS Developer's Playbook: Mastering SwiftUI Forms

In this article we’re going to examine how a SwiftUI Form can used in our SwiftUI apps. This will be a very technical article useful for any iOS developer, during which we’ll take a deep-dive into the code and then create a SwiftUI Form that combines a user profile with a settings screen. Table of Contents.

Swift Code Analysis: Integrating Sonarqube

SonarQube is an open-source platform that allows you to continuously inspect and measure code quality as you develop your project. It provides static code analysis for code issues, security issues, and code smells in various programming languages, including Swift. This helps development teams maintain and improve code quality by identifying and finding issues in the development lifecycle, if paired with a good testing methodology it can make a difference in your app quality.

Unlocking the Power of Swift Generics: A Comprehensive Guide for Developers

Swift is a high-level programming language developed by Apple, which first appeared on June 2, 2014. Swift is vast and complex, containing all the major features we expect in a modern programming language. Generics are one of the most fundamental tools in all of Swift, empowering us to write more abstract, reusable and clean code. With Generics, we can use different data types in the same functions and classes, with minimum assumptions.

Understanding SwiftUI Pickers: Usage and Styling Techniques

Pickers are UI elements, provided by SwiftUI, that enable our users to choose between multiple options while using our iOS app. In this article we’ll have a look at them to see the various types and explore how they’re declared, configured, and styled. Together with SwiftUI buttons, pickers are one of the most used UI elements in iOS apps.

Advanced Swift Arrays: Explore Sort, Filter, Map and Reduce and more

Arrays enable you to group and order elements of the same type, so they play a crucial role in organizing your app’s data. If you’re building an iOS app, arrays are a vital part of your toolkit, and today we’re going to help you understand them. Specifically, we will give you a backend view of how Arrays work and jump into a host of specific operations, from simple filtering and sorting to complex ways of mapping and reducing them.

iOS Geofencing: Unlocking Location-Based Capabilities for Swift Developers

In iOS, geofencing is a location-based feature that enables us to define geographical boundaries and trigger actions, or alerts, when a device enters or exits those boundaries. This feature has become vital to all kinds of apps, enabling them to deliver personal, timely and contextual experiences.
