[feat] v2: Frameworks aren't being picked up for iOS builds

[stijnfrishert]

Describe the bug

I'm using a Rust crate that depends on coreaudio-rs. For this work work on macOS/iOS, I need to link against the CoreAudio framework.

I'm building for iOS (using the v2 beta) and the linker tells me it's missing core audio symbols.

I've tried setting bundle > iOS > frameworks to [ "CoreAudio" ] in tauri.conf.json, but I get an error that the "frameworks" property is not allowed.

I've also tried setting the same on bundle > macOS > frameworks, but that doesn't help. Neither do I see --framework CoreAudio show up in the linker command.

Expected behavior

I would expect bundle > iOS > framework to be valid and insert the frameworks into the linker command

@FabianLars I'm yet unfamiliar with the Tauri internals, but if you could point me in the right direction I'm willing to try my hand at a PR :)

I haven't tried it on the release build, but for the dev build, I think the easiest way to embed the framework now is using pnpm tauri ios open to open the project in Xcode and add the framework from it.

Thanks, @pewsheen, didn't know that was possible, so I learned something. 😄

Decided to go the PR route and learn something about Tauri's internals. Hopefully someone will pick up the PR soon and help me with some remaining questions. :)

I've got "coreaudio" to at least compile using these frameworks:

"iOS": {
      "frameworks": [
        "AudioToolbox",
        "CoreAudio",
        "OpenAL",
      ]
    }

though I didn't manage to make their Rust example work (seems like it's crashing, maybe it's missing some delegate code like they have in their iOS example)
