Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Kaleidoscope of iOS app architectures
TCA for short. Very scalable, quite promising, quite popular. A decent alternative for MVVM enhanced by the Clean Architecture. You can learn more about it in a Point-Free tutorial and on GitHub.
-
My largest project yet: A fully themable, powerful task manager and daily planner built with SwiftUI. Available on iPhone and iPad for free (no ads, IAP or data collected).
🙏 Built with SwiftUI and The Composable Architecture (TCA): This isn’t a feature, but I just want to express my gratitude to the creators and maintainers of these two frameworks, which have played a huge part in making me fall in love with iOS development.

Koji je vas odnos prema alternativnim hype-ovanim paradimama programiranja, frameworcima i tehnologijama?
Razliciti alternativni frameworci i arhitekture - Recimo, na pamet mi padaju Composable Architecture (https://github.com/pointfreeco/swift-composable-architecture) i RIBs arhitektura (https://github.com/uber/RIBs). Ok, ove arhitekture resavaju neke probleme. Ali da li problemi koje te arhitekture resavaju solidan developer ne moze sam da resi bez vendor locka za kreatore tih arhitektura. Jesu one open-source, ali meni je rizik da se vezujem za bilo sta sto sutra moze da prestane da se odrzava.

What design patterns exist and which should I learn for SwiftUI?
I came across this post discussing MVM, MVVM, MVP, and composable architecture.
-
What is a piece of code (or Framework, extension, etc.) that you add in every new project?
At a minimum, Composable Architecture, and now Dependencies from Point-Free.
-
Ideal architecture for an app entirely in SwiftUI? Example code repo would be great
I’ve built a couple of apps with this framework: https://github.com/pointfreeco/swift-composable-architecture
- Use of EnvironmentObjects for sharing ObservableObjects
-
Best way forward coming from the Javascript / Typescript world?
While there are apps that use a Redux-style architecture, the arch is still in its infancy in the community. There are a number of implementations each with their own take on Redux. TCA is probably the one with the most name recognition and documentation.
-
Should You Still Learn UIKit?
Learn it if the project at hand requires it. A lot of older, more mature apps will still use UIKit, so it’s likely if you plan to work an iOS developer job that you will need it. But it’s getting to the point where a lot of the forward thinking shops are already starting to integrate SwiftUI. (Me being one of them) which, btw, a lot of people will say SwiftUI isn’t quite there yet, and I mostly disagree. SwiftUI is good for a great many use cases. Yes, there are still pain points, but you can write most of the apps you’d need to write in SwiftUI. And there are great architectural frameworks out there that actually give SwiftUI an opinionated way to structure apps that is testable and maintainable.

Byte-Sized Swift: Building Tiny Games for the Playdate
[A Vision for Embedded Swift](https://github.com/apple/swift-evolution/blob/main/visions/e...) has the details on this new build mode and is quite interesting.
> Effectively, there will be two bottom layers of Swift, and the lower one, “non-allocating” Embedded Swift, will necessarily be a more restricted compilation mode (e.g. classes will be disallowed as they fundamentally require heap allocations) and likely to be used only in very specialized use cases. “Allocating” Embedded Swift should allow classes and other language facilities that rely on the heap (e.g. indirect enums).
Also, this seems to maybe hint at the Swift runtime eventually being reimplemented in non-allocating Embedded Swift rather than the C++ (?) that it uses now:
> The Swift runtime APIs will be provided as an implementation that’s optimized for small codesize and will be available as a static library in the toolchain for common CPU architectures. Interestingly, it’s possible to write that implementation in “non-allocating” Baremetal Swift.

Borrow Checking Without Lifetimes
I may be out of my depth here as I've only casually used Rust, but this seems similar to Swift's proposed lifetime dependencies[1]. They're not in the type system formally so maybe they're closer to poloneius work

Functional Ownership Through Fractional Uniqueness
Swift recently adopted a region-based approach for safe concurrency that builds on Milano et al’s ideas: https://github.com/apple/swift-evolution/blob/main/proposals...

Crafting Self-Evident Code with D
No, it's not. Refcounting CAN be a garbage collection algorithm, but in Swift it's deterministic and done at compile time. Not to mention recently added support for non-copyable types that enforces unique ownership: https://github.com/apple/swift-evolution/blob/main/proposals...

You can stackallocate buffers with unsafe Swift but it's not exactly fun to use. https://github.com/apple/swift-evolution/blob/main/proposals/0322-temporary-buffers.md

Can someone explain how Task really works in terms of threads (I couldnt ask all the questions with the swift team today)?
If the docs do not suffice, read the concurrency proposals of Swift Evolution. The authors describe the semantics in a very detailed way there.
