Sourceful VS swift

This might be a good place to start.

www.hackingwithswift.com has good free resources and also some paid. Good place to start ;)

Sometimes the documentation can feel incomplete… though sometimes there are some really helpful tutorials. Once place I’ve found good info is from WWDC. Another is from Paul Hudson on https://www.hackingwithswift.com

Check out these resources.

For example, Paul Hudson's Hacking with Swift has 100 days of Swift and 100 days of SwiftUI. The first 15 days are dedicated to basics of programming like learning about variables, dictionary, etc. maybe you can skip through those but I would still look into topics like extensions, protocols, etc.

iOS programming is really straightforward, and with the advent of Swift and SwiftUI, it is really accessible. I kicked around an idea last year, and managed to get quite a decent prototype together very quickly. It doesn't have the best documentation for the language and software development kits, but there are loads of resources on the internet (Hacking with Swift is a good place to start).

Because of C/C++ interop, and integration with CMake, you can just add Swift to a Zephyr project and it pretty much Just Works. [The docs](https://github.com/apple/swift/blob/main/docs/EmbeddedSwift/...) should mostly apply to the Zephyr SDK as well.

Fortunately, the Observation framework is part of the Swift 5.9 standard library. We can learn more information by examining its source code.

They do! See https://github.com/apple/swift/blob/main/docs/LibraryEvoluti...

You can also see an example of what a different high level language integration with Swift ABI looks like here: https://github.com/dotnet/designs/blob/main/proposed/swift-i...

So is differentiable Swift a package for Swift or is it part of the Swift standard library? The video says go to swift.org but I can't find any info about differentiable Swift on that site.

Swift's Differentiable Programming Manifesto. Swift has a powerful differentiable programming component, integrated with the compiler.

You can do the same thing the other way around - https://github.com/apple/swift/blob/main/docs/Android.md.

Codable (along with other derived conformances like Equatable, Hashable, and RawRepresentable) is indeed built in to the compiler[0], but unlike Serde, it operates during type-checking on a fully-constructed AST (with access to type information), manipulating the AST to insert code. Because it operates at a later stage of compilation and at a much higher level (with access to type information), the work necessary is significantly less.

With ongoing work for Swift macros, it may eventually be possible to rip this code out of the compiler and rewrite it as a macro, though it would need to be a semantic macro[1] rather a syntactic one, which isn't currently possible in Swift[2].

`Int` is a regular struct with a single stored property of type `Builtin.Word` . But the latter is a magical compiler built-in. Source for integer types is generated from this template - https://github.com/apple/swift/blob/9da65ca0a15fdf341649c994b0a77ec3b71f2687/stdlib/public/core/IntegerTypes.swift.gyb
