In Swift, both classes and structures are used to define custom data types — but they have different behaviors, especially in memory management, inheritance, and value/reference semantics.

GCD (Grand Central Dispatch) is a low-level concurrency framework provided by Apple to help you manage multithreading and execute tasks asynchronously or concurrently in iOS/macOS apps.

In iOS development with UIKit, every UIViewController goes through a clear and predictable life cycle. It all starts when the controller’s view is first loaded into memory, continues as it appears on screen, and ends when it’s no longer visible or needed. Understanding this life cycle helps you know the right place to set up your UI, load data, and clean up resources. Each phase from viewDidLoad to viewWillAppear, viewDidAppear, and eventually viewWillDisappear and viewDidDisappear gives you a chance to hook into what’s happening and respond appropriately.

When developing iOS apps, code organization is just as important as writing it. Design patterns like MVC, MVVM, and MVP help you separate concerns, reduce code duplication, and make your app easier to test and maintain. Each pattern has its strengths and fits different use cases, depending on the complexity of your app and the tools you’re using UIKit, SwiftUI, Combine, etc. Let’s break down how these patterns work and where they’re most useful.

SOLID is the official acronym for five design principles that help developers write clean, maintainable, scalable, and robust object-oriented code. These principles were introduced by Robert C. Martin (Uncle Bob) and are widely used in Swift, Java, C#, and other OOP languages.

The iOS application life cycle is all about how your app moves between different states; from launch, to background, to being closed. Knowing how this flow works helps you save data, clean up memory, pause tasks when needed, and handle interruptions like phone calls smoothly.

IoT technology has made it possible for devices and sensors to communicate seamlessly, which has given iOS app developer’s new options. hire ios developer who is skilled in developing and connecting iOS apps and smart devices that gather data in real-time, and provide users with customized experiences. The need for the iOS apps market is growing and is well connected with the Internet of Things used in smart gadgets like wearables, smart devices, and home appliances to gain more traction.

Modular development is a significant advantage of Angular development services. In this instance, mobile applications are separated into manageable, compact pieces. Developers may now create apps with disparate components that function as a whole. It makes debugging and development easier.

Best suited for deployment of trained AI models in Android and iOS operating systems, TensorFlow Lite provides customers with on-device machine learning capability through mobile-optimized pre-trained models. It’s efficient while having low latency and compatibility for multiple languages which makes it very versatile. Developers can leverage its lightweight and mobile-optimized models to provide on-device AI functionality with minimal latency when implementing TensorFlow Lite in mobile apps.

Google’s chaos makes Apple’s control seem reasonable. I can already hear John and Seb typing: “…and this is why the EU shouldn’t turn Apple into Google.” Let’s be real—Google Play and the App Store don’t compete. They collaborate. Same rates, same model, same unchecked power. Call it a monopoly, call it a duopoly. They share the mobile market without too much crossfire: Apple takes those who can or want to pay, Google takes the rest. Google Play is not an alternative to the App Store. It’s not “Go there if you don’t like Apple.” Google Play is a very lazy, very sloppy carbon copy of the App Store. Their collaboration is not metaphorical. It goes beyond the way their shared control over the mobile app market. Apple collects privacy points, then cashes them in by making Google the default search on iPhone. A lot of that privacy-free Search money flows right back from Google to Apple. 20 Billion USD in 2022. In 2020, “Google’s payments to Apple constituted 17.5% of the iPhone maker’s operating income.” (Bloomberg) And no one really cares, as long as it’s convenient. But as a developer in Europe, we’re glad that the EU does. ↩

The most straightforward way to transcribe audio from an existing file is to open the audio or video file in Drafts. Here’s a few of the ways to access transcription: iOS Tap and hold the “+” button for new draft options, select “Transcribe…” Use a share button in another app (such as Voice Memos, or the Files app) that can share audio or video content, then select Drafts in the share sheet.

the Openmargin iPad app announced in late April (http://www.the- digital-reader.com/2011/04/28/openmargin-brings-margin-notes-to-life/) looks very interesting.

I noticed fairly quickly that the iOS app was a re-branded release of what used to be Mast. My first instinct upon this discovery was to DM Mast's original developer, Shihab Meboob, on Twitter, but frankly, I've already bothered him enough there over the years, so it's understandable that I didn't hear back. When I downloaded the desktop app I found on Roma's web page and noticed its similarity to Whalebird, I decided to use the site's contact form to inquire about what exactly was going on as gingerly as I could. Happily, I received a reply just *minutes- later from Leo Radvinsky, head of Leo.com, “a Florida-based boutique venture capital fund that invests in technology companies:” Hi David, In both cases we funded the original developers of both Mast and Whalebird to create a branded whitelabel app specially made for Pleroma. The idea was to make Roma a cross platform brand/app. It didn't really work out so now we're working on a new app from scratch called Fedi for iOS and Android and releasing that as open source. https://play.google.com/store/apps/details?id=com.fediverse.app&hl=en*US&gl=US https://apps.apple.com/in/app/fedi-for-pleroma-and-mastodon/id1478806281 I think Roma has been removed from the app stores as it's no longer supported. Let me know if you have any other questions

“Find Notes” can now retrieve more than 26 notes at a time

The absence of Quick Note on the iPhone is a strange, glaring omission that’s baffling to me. I do research on every device, including the iPhone. In fact, I’d argue that the iPhone is the most important place to include Quick Note. That’s because, despite the ample screen of my iPhone 12 Pro Max, it’s still not the best place to read, making saving items for later with Quick Note more valuable there. However, my iPhone is still where I run across links and other material I want to save daily. I’d love to be able to drop links and blockquotes into Quick Note from my iPhone, so I could revisit the material later from the more comfortable reading environment of my iPad or Mac. Not having Quick Note on the iPhone is a significant blow to the feature’s utility.

Removed UI Sounds

So, if you are still in a quandary for your iOS mobile app development, hang on; the blog would throw light on which technology can work like a boon for your project.

With text replacement, you can use shortcuts to replace longer phrases. When you enter the shortcut in a text field, the phrase automatically replaces it. For example, you could type "GM" and "Good morning" would automatically replace it.  To manage text replacement, tap Settings > General > Keyboard > Text Replacement.  To add a text replacement, tap the Add button , then enter your phrase and shortcut. When you're done, tap Save.  To remove a text replacement, tap Edit, tap the Remove button  then tap Delete. To save your changes, tap Done.

In a new article, the New York Times details a little-known technique increasingly used by law enforcement to figure out everyone who might have been within certain geographic areas during specific time periods in the past. The technique relies on detailed location data collected by Google from most Android devices as well as iPhones and iPads that have Google Maps and other apps installed. This data resides in a Google-maintained database called “Sensorvault,” and because Google stores this data indefinitely, Sensorvault “includes detailed location records involving at least hundreds of millions of devices worldwide and dating back nearly a decade.”

A completely different Service Workers’ storyThis section was added on Feb, 8th.Apple followed the Service Worker API, but it creates an entirely different story of what it is and what we can do with it in the future. The main differences appear when Apple says:“To keep only the stored information that is useful to the user, WebKit will remove unused service worker registrations after a period of a few weeks. Caches that do not get opened after a few weeks will also be removed. Web Applications must be resilient to any individual cache, cache entry or service worker being removed.”https://webkit.org/blog/8090/workers-at-your-service/That is a huge change! At Chrome, Firefox, Samsung Internet, and other browsers, a Service Worker registration is not going to be unregistered automatically, and we can rely on being there in the future. That’s why an installed PWA will be able to work offline in the future. But with Apple’s idea of a service worker, there is no guarantee that the service worker or the cache will be available in the future. It might be if the user comes back to the web app within “a few weeks.” I know, the web app should work anyway while online, but we can’t guarantee one of the key concepts of PWAs: offline access.

In addition to using the catalog for the 2017-2018 school year, school performance data for the past three years has been uploaded into the app. Altogether this year, 120 teachers and almost 1,500 students will benefit from this solution in Alba Iulia. With e-album iulia, available on Android and iOS, tourists have access to information about the city's main objectives, and local businesses can hold dedicated campaigns.

Accessing a Webpage

In Share extensions (on both platforms) and Action extensions (iOS only), you can give users access to web content by asking Safari to run a JavaScript file and return the results to the extension.

On both platforms, your custom JavaScript class can define a run() function that Safari invokes as soon as it loads the JavaScript file. In the run() function, Safari provides an argument named completionFunction, with which you can pass results to your app extension in the form of a key-value object. In iOS, you can also define a finalize() function that Safari invokes when your app extension calls completeRequestReturningItems:completion: at the end of its task. A finalize() function can use items your extension passes in completeRequestReturningItems:completion: to change the webpage as desired.

Create a JavaScript file that includes a global object named ExtensionPreprocessingJS. Assign a new instance of your custom JavaScript class to this object.
