GSoC 2021: Referencing enclosing self in a property wrapper type

[KyungyoungHeo]

Hello, I'm Kyungyoung Heo, I am a senior at Soongsil university, South Korea. I have an experience with Swift, C/C++, Python. And I love to develope an iOS App and using Swift. I've done few projects in iOS.

• Converting images into scanner result like Deep learning powered scanner vFlat.
• Implementing AAAI2020 paper in iOS Few-shot Face Reenactment MarioNETte

Property wrapper looks so interesting for me since first introduced at WWDC 2019. I'm so interested project by @hborla and would like to participate in GSoC 2021 with property wrapper project.

I just read @hborla's other previous reply, and plan to analyze and read SE-0258 proposals, Pull Request, and source code in lib/Sema/CodeSynthesis.cpp , lib/Sema/TypeCheckPropertyWrapper.cpp

Before digging into this project, I just wonder those materials are good to digging or not. Please advise me.

It would be great to if I could contact you to discuss with.

Thanks,
Kyungyoung Heo

Hi Kyungyoung, welcome to the Swift community!

I just read @hborla's other previous reply, and plan to analyze and read SE-0258 proposals , Pull Request, and source code in lib/Sema/CodeSynthesis.cpp , lib/Sema/TypeCheckPropertyWrapper.cpp

Yes, these are good resources to start with for this project. I recommend to focus on the language design side first, sketch out a rough idea (or a few ideas!) of how the feature could work, and then dig into the code and figure out how you could implement the feature.

I also wrote up some more guidance here:

[GSoC 2021] Referencing enclosing self in a property wrapper type

Hi Siddharth, welcome to the Swift Community! As a first step, I recommend reading the Swift evolution proposal for property wrappers. Everything through the Detailed Design section will give you a much more in-depth understanding of property wrappers and how they work. After that, focus on the future direction for referencing enclosing self instance in a property wrapper. Once you've done that, continue reading the rest of this post! I recommend getting familiar with the memory exclusivity …

Please let me know if you have any questions!

Thanks for reply. I'll look design first then dig into code as you said.
