Let's GOOO! #BlueJays

After 32 freaking YEARS (or I think that's the last time they did this: I don't remember the number)!

You BETTER not mess this up, Blue Jays.

I didn’t expect to get to 185 stars for ATProtoKit. Thank you very much! I’m humbled for your generosity and support. 🙏

Please do continue to boost this project higher: if you can get it to 200 by the end of the year, I would greatly appreciate it.

In an effort to improve documentation, I've been in the process of writing an article that explains how lexicon models are supposed to behave. In general, this should help developers understand what to expect when using them. ATLexiconC will strictly abide by these rules as well.
Serialization and Validation Behavior in Lexicon Models Learn how lexicon models are expected to behave within ATProtoKit. ATProtoKit’s lexicon model types implement custom `Codable` logic to support the AT Protocol’s specific data serialization and validation requirements. This article explains the common encoding, decoding, and validation rules applied across lexicon models, including date handling and field length/array size enforcement. Overview While lexicon model in ATProtoKit conforms to the `Codable` protocol, not all rely on the standard synthesized implementations. Instead, many models provide explicit implementations of: - A custom `public` initializer, - a custom `Decodable` initializer, - a custom `Encodable` method, and - a custom `CodingKeys` `enum`. By having explicit implementations, ATProtoKit can help ensure the models are consistent with the lexicon the `struct`s are following, and the [...]

How the Hell is this 8 TB SSD so damn small? I'm a bit worried that the read/write cycles aren't that high...

Hmm... I'm a bit stuck here.
Screenshot of the Xcode source editor. The code says: " public func makeIterator() -> [String: Lexicon].Values.Iterator { return self.lexicons.values.makeIterator() } " The error says: "Actor-isolated instance method 'makeIterator()' cannot be used to satisfy nonisolated requirement from protocol 'Sequence'."

I guess I can change this text in the README the next version, then. Cool!

I'll just mention that it requires Swift 6.1 and that the minimum requirement is Windows 10, but also mention that ARM builds are not supported at this time.
Warning: As of right now, Windows support is theoretically possible, but not has not been tested to work. While it’s not a goal to make it fully compatible, contributions and feedback on the matter are welcomed.

Well... I think this works.

Next.

Oh right, this is what I mean by "superRefine".

This is confusing as Hell. I can decode it eventually, but how the hell am I supposed to make a mini-compiler that translates... this?

It's not bad (in TypeScript standards), but it's just so damn hard to read for me.
export const oauthAuthorizationServerMetadataValidator = oauthAuthorizationServerMetadataSchema .superRefine((data, ctx) => { if ( data.require_pushed_authorization_requests && !data.pushed_authorization_request_endpoint ) { ctx.addIssue({ code: z.ZodIssueCode.custom, message: '"pushed_authorization_request_endpoint" required when "require_pushed_authorization_requests" is true', }) } }) .superRefine((data, ctx) => { if (data.response_types_supported) { if (!data.response_types_supported.includes('code')) { ctx.addIssue({ code: z.ZodIssueCode.custom, message: 'Response type "code" is required', }) } } }) .superRefine((data, ctx) => { if ( data.token_endpoint_auth_signing_alg_values_supported?.includes('none') ) { // https://openid.net/specs/openid-connect-discovery-1_0.html#rfc.section.3 // > The value `none` MUST NOT be used. ctx.addIssue({ code: z.ZodIssueCode.custom, message: 'Client authentication method "none" is not allowed', }) } })

Just to show you there’s no OpenSearch client in Swift (or at least, none that’s been indexed into Swift Package Manager).

TL; DR:
A checklist inside a Notes window. Text: Tasks for the Week of July 7, 2025 - ATProtoKit - Release version 0.30.1. - Update lexicon models and methods. - Implement PR merge related to public initializers for three lexicon models. - ATCryptography - Add overloaded signature verifier methods to support JWTs. - ATCommonTools - Investigate Swift equivalents for common/streams.ts. - Determine whether InputStream, AsyncStream, or another solution is most appropriate. - Begin Swift implementation of common/streams.ts. - swift-mst - Rename package to swift-atproto-mst. - ATLexiconTools - Convert serialize.ts to Swift. - Tweak blob-refs.ts Swift implementation. - Lexicon Generator - Work on converting remaining lexicon structs to OpenAPI structs. - Test implementation to ensure it works with the lexicon models.

Version 0.29.0 of ATProtoKit can now build on Android. Great!

However, it fails on Wasm, which is... interesting.

When looking at the logs, there are multiple places where it tells me to import FoundationNetworking.

But I have the following in APIClientService.swift:
