Yup, that API is blocked (by Apple) behind code signing requirements. You should look up how to run codesign - and you might want to use cargo-bundle to make life easier. The iOS example in this repository does use codesign IIRC.

I should probably throw together a demo of this. Alas, I am sitting in a bar with my wife right now so this… will wait, lol

(I will say, if it compiles, your Rust side is likely correct)

Hello, I'm testing desktop notification using cacao in my repo, cacao_playground.

I just added one line for notification based on hello world. But I get an error like this when I run cargo run. I saw a readme in cacao but doesn't understand this word

Note that this requires your application be code-signed, and will not work without it.

What am I doing wrong?

Good catch! Will merge this when I have time. Would love a PR’d demo as well if you’re up for it. ;)

Signing can be confusing but isn’t too bad…

Thanks!

Hello, while I'm testing whether desktop notification works if I use cacao (testing in my cacao_playground repo), I found user_notifications/mod.rs has called deprecated function of NSString.

I looked up the file history and found that NSString once had a function wrap but it seems to be replaced into reatin function.

So I made a simple change :D

@DanielFore This shouldn't be a hot take, and should be shouted from the rooftops every time people complain about it. 2 days ago
One of the most gratifying feelings is when you see someone who you mentored finally "get it" and they're unleashed in terms of skill.

My browser feature request: any link that auto-opens in a browser, open it in a private tab. Let me de-escalate it to a normal tab if I think the content is fine.

Use case: someone passes a link they don't realize is some conspiracy theory. Guess what I'ma get ads for now? ;P 5 days ago

@Neil_BIM Alas I live a Facebook-free life, so that's out of the realm of possibilities.

For what it's worth, the codesigning requirement does get a bit odd for people just looking to release a cross-platform tool. There's realistically an argument to just keep using the older API until it well and truly stops working.

If you wanted to upgrade mac-notification-sys to use the newer API, there's a few things I can think of off the top of my head that are worth noting:
- Definitely feel free to borrow and/or extend the code I used in cacao. I'd be happy to be a second pair of eyes or a sanity check if it's helpful.
- For an app that's going to be a complete .app bundle, the codesigning requirement isn't too thorny. cargo-bundle coupled with a codesign script has worked fine for me in the past.
- For an binary that's not a .app bundle, you could likely make use of the API by embedding the Info.plist. You'd need to pass something like -sectcreate __TEXT __info_plist /path/to/Info.plist as a linker flag, and then run codesign on the resulting binary with an appropriate entitlements file.
- I would maybe keep both APIs (old and new) around, so users in development mode could build and test without needing to go the full codesign route from the start. on Switch to UN* API
