objc is least likely to merge the PR, so what would be a good course of action here? patch or put a objc2 under Tauri?

@pewsheen is working on porting wry to objc2 already but it's a lot of work.

[eugenehp]

Nice! There's also objc2 by @madsmtm but it doesn't have full API parity with the original objc as far as I know.

So for the time being, what would be the appropriate way to patch this in Tauri (Wry and Tao) @FabianLars

[FabianLars]

tbh I'd probably wait and see if we can get wry ported in time, especially considering that we're still waiting for other projects than objc. Devs that want to use it earlier can use cargo's patch feature to overwrite the crates.io version with your forks.

[eugenehp]

Sounds good. That's what we're using right now – patches. Thinking maybe to put some temporary crates on crates.io to make things easier later, if no news on merging/porting main repos.

Linking the issue in Wry for tracking the migration to objc2: tauri-apps/wry#1239

Nice! There's also objc2 by @madsmtm but it doesn't have full API parity with the original objc as far as I know.

Could you expand on what it's missing compared to objc? It's originally a fork of that project, so it should have full feature-parity (and more, ofc ;) ).

[eugenehp]

Oh, perfect, I missed that one. Commented there, in case I can help speed things up.

[aralroca]

Looking forward to this feature 🔥

It's 2026, what's the progress now?

[eugenehp]

Some PRs are outdated now, so they will have to be migrated to objc2 an update to the latest main branch.

I think in rust repo there was a push to formalize platform support as tier 3.
