...Build cross-platform apps that have similar architecture, enabling iOS and Android teams to cross-review business logic code. Testability and Isolation. Classes must be easy to unit test and reason about in isolation. Individual RIB classes have distinct responsibilities like routing, business, view logic, creation. Plus, most RIB logic is decoupled from child RIB logic. This makes RIB classes easy to test and reason about independently. Tooling for developer productivity. RIBs come with IDE tooling around code generation, memory leak detection, static analysis and runtime integrations.

...Like other Rx implementation, RxSwift's intention is to enable easy composition of asynchronous operations and streams of data in the form of Observable objects and a suite of methods to transform and compose these pieces of asynchronous work. KVO observation, async operations, UI Events and other streams of data are all unified under abstraction of sequence. This is the reason why Rx is so simple, elegant and powerful.

...Topics range from language fundamentals (memory management, ARC, value vs. reference types), to UIKit/SwiftUI, concurrency, Grand Central Dispatch, background execution, networking, design patterns, system frameworks, and architecture decisions. Each question is usually backed by sample explanations or code snippets, helping candidates understand not just what to answer but why it matters and how to reason about tradeoffs. Because the repo is maintained, it evolves to reflect changes in the iOS ecosystem: for example, newer Swift concurrency, Combine, SwiftUI, structured concurrency, or recent platform APIs. Many interviewers and candidates use it as a structured prep tool: reviewing categories, doing mock answers, or drilling tricky concepts.

When you load a JPEG image in Delphi (both VCL and FMX), the image might appear rotated or even mirrored. This is often the case, when the image is a photo taken with a smartphone in portrait mode. The reason is that the JPEG contains an additional "Exif" header, which specifies the orientation of the image. In order to display the image correctly, you must read the Exif header and rotate, flip or mirror the image after loading, according to the orientation information in the Exif header. This small unit does it for you: it is the smallest and fastest JPEG Exif reader currently available for Delphi and automatically applies the necessary transformations to a TBitmap object after loading. ...

The gap between performance and experience has always been the primary reason for mobile app developers to abandon HTML5. The browser’s natural page-cutting white screen, the unbearable turning animation, the jittering of floating elements, and the inability to pull down to refresh smoothly, all of which frustrate HTML5 developers, especially when they get a low-end Android machine to run, and the phone falls.

Katana is a modern Swift framework for writing iOS applications' business logic that are testable and easy to reason about. Katana is strongly inspired by Redux. In a few words, the app state is entirely described by a single serializable data structure, and the only way to change the state is to dispatch a StateUpdater. A StateUpdater is an intent to transform the state, and contains all the information to do so. Because all the changes are centralized and are happening in a strict order, there are no subtle race conditions to watch out for. ...

...It also covers architectural and performance topics such as dynamic layout optimization, view lifecycle subtleties, Swift language pitfalls, and integration with low-level APIs such as Metal or CoreAnimation. By aggregating authoritative references, experiments, and code snippets, the guide helps developers reason through tradeoffs, debug subtle issues, and architect large-scale iOS systems.
