iOS Resources

In 2020 Apple came up with an updated vision of widgets and unified their API across platforms. The new WidgetKit framework made widgets more accessible, interactive and increased SwiftUI adoption. Starting with iOS 14, widgets can be presented in multiple sizes and placed on the iOS Home screen, Today View, or macOS Notification Center.

This article shows how you can easily map Firestore documents to Swift types using the Codable API.

If you've made a custom app for an organization, you'll need to distribute it privately. Here's a guide to private app distribution for iOS.

Apple has recently published a proposal to add a coroutine model to the Swift programming language. It brings a more convenient, efficient, and safer way to manage concurrency programming. The Async/Await syntax was introduced in the first phase of structured concurrency to allow users to organize complex asynchronous calls in the normal control flow mechanisms.

What if I told you you can use what you already know as an iOS developer for backend development?

Networking is a requirement for most modern iOS apps. Apps usually interface with a remote web service. And often, such a web service is a REST API that returns JSON data.

Writing the networking layer of an iOS app is not a simple task. When making asynchronous network calls, you need to combine several features of Swift, SwiftUI, and the Foundation framework. Moreover, many parts of your app’s architecture need to interact, making the task more complicated than it might seem at first.

The Python has a math module which contains number of functions that are available for mathematical operation. The functions and constants of math module are listed below:

Localizing in SwiftUI is easy with this tutorial. Simply identify the texts to be translated, add them to a localization file for your translators to work on. At runtime, your iOS/Mac app will show the right translation to the user based on their own language preferences.

The "Missing" Localization Glossary for Apple terminology in a dozen languages for common terms like Settings, Preferences, Copy & Paste, etc. Since Apple does not provide one, this is a great resource.

Full list of the languages and locale codes used by Apple for iOS and Mac apps. These are used to name localization folders (e.g. fr.lproj).

A thorough tutorial with pictures to walk through localizing an iOS/Mac app for the first time using Xcode. Steps include:
1. Preparing your iOS app for localization in Xcode 12.x
2. Extract your hard-coded strings to NSLocalizedString()
3. Use Xcode's import/export localization features

SwiftUI offers several mechanisms to pass data between views.

Such abundance can make it hard to decide which data flow mechanism fits any particular situation.

Those decisions cannot be taken in isolation. As in many other cases, we need to keep an app’s architecture in mind to make the correct choice.

User behavior can be a major head-scratcher. Every mobile product manager needs analytics tools to help them parse the data — we've got recommendations.

The goal of those animations challenges is to try to analyze existing animations and try to replicate them. This articles showcases the usage of UIKit Dynamics ( real physic-like animation ) on iOS.

To create an adaptive UI that responds appropriately to changes in screen size and device orientation, we use Auto Layout, the constraint-based layout system. This article gives an overview of five different approaches to adding constraints programmatically.

Since the introduction of SwiftUI, the MVVM pattern has seen a new renaissance. Many developers believe that this particular pattern fits well with the SwiftUI data flow.
MVVM certainly has some good ideas, but it also brings along problems because of the various discording interpretations of the pattern and its rigidity.
In this article, we will see how MVVM fits in iOS apps written in SwiftUI, how to take advantage of its benefits, and how to avoid its problems.

On some projects, we need the client to be able to communicate with the server in real-time. The Websocket protocol works over the TCP socket connection and provides the ability of real-time, bi-directional communication between client and server.
The article gives a simple guide to set up the WebSockets API service on AWS, by using the serverless framework, API Gateway, and DynamoDB.

Lofelt brings Apple's Core Haptics API to life, making it easy to create immersive experiences that draw users into your app.

Core Haptics has huge potential, but it’s time-consuming to painstakingly, manually code. With Lofelt Studio, you supply audio files and they are automatically translated into easily adjustable instructions for Core Haptics that deliver immersive haptic experiences. This brings a tactile sensation to apps that matches the visuals and audio.
