Swift SDK For TON

[nerzh]

Summary

This footstep is for the development of the Swift SDK. Swift is popular not only among mobile developers, but has also had a significant server-side community. Developing such a package will help open access to the TON for both mobile and server developers. I haven't found a native implementation of TON primitives in footsteps, so I'm creating this footstep. As an active Swift community activist with experience in both mobile and server development, I'll take great pleasure in developing this package.

Context

Here is a development plan that I would like to implement as part of this footstep:

• Implement Cell, Slice, Builder and BOC (de)serialization
• Implement an RPC client to work with the TON network
• Implement support for popular structures from block.tlb
• Implement support of TON base64 addresses
• Implement support of HashmapE
• Implement support of TON & BIP39 Mnemonics
• Implement support of wallets (v3, v3r2, v4r2)
• Ed25519 signing of transactions
• Implement for workings with Jettons and NFTs

Goals

Develop the Swift SDK to work with the TON blockchain

Deliverables

GitHub with Swift SDK library and examples

Definition of Done

GitHub repository with the source code

Reward

• 5,000 USD in TON equivalent
• Standard TON Footstep NFT

Oriental Release Date

27/11/2023

In which scenarios do you envision using Swift for development? I genuinely question its practicality for most users, and maintaining such a platform could be labor-intensive.
For now, I have to close this issue. However, should there be a future demand from the community for such a solution, feel free to submit a new request, and we'll certainly review it.

@delovoyhomie
Swift is a relatively young language, and as a result, not many people are aware that it is already available not only on Apple's mobile platforms but is also actively used on other popular platforms such as Linux, Windows, and more. Swift also has a thriving and rapidly evolving Server Side community (https://www.swift.org/sswg/). It's also worth noting that Swift is the only language for professional application development across all of Apple's platforms, including MacOS, iOS, watchOS, and more.

By analogy, you can see how languages like Kotlin are gaining momentum in cross-platform development. Swift is also keeping up with these trends.

I also understand that I already have experience in developing similar libraries (in Ruby), but development in Swift may take more time because this language is lower-level than Ruby and has strict type system like Rust.

I consider a reward of 3,000.00 USD to be a suitable reward for this task.

Through our personal discussions, we've outlined a promising future for the Swift SDK and agreed upon a suitable reward.
Let's get started!

Hi, I am happy to announce that I have finished and tested my solutions for Swift. And also that I have done a bit more and added Highloadwallet_v2 to the library for Swift as well as for Ruby
