[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.

[stijnfrishert]

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)

Hello !
Any news about a doc section for embedding frameworks into apps ? I want to use tauri-plugin-nfc on my iOS app, but I struggle with the whole dynamic framework libraries and embedding thing.

Thanks for all the work !

[stijnfrishert]

From the way I've used it, it's quite easy: any of the Apple frameworks you use need to be listed under bundle/ios/frameworks in your Tauri config file, and will be picked up by the build system.

Note that you have to rerun tauri ios init to get this to work, and iirc I even had to throw away the gen/apple folder a couple of times for changes to get picked up.

As to which frameworks are required for the tauri-plugin-nfc plugin are required for it to work, I have no idea, but that should be figure-outable.

The thing is that the framework I need, CoreNFC is a dynamic framework. And I face a lot of issues to embed this framework into my bundle, as this is required for dynamic frameworks
If I find any solution I will open a documentation PR.
