[bug] [ios] Cannot build for iOS (building for 'iOS', but linking in object file built for 'zippered(macOS/Catalyst)')

venkr commented 4 months ago

Describe the bug

I'm trying to build an existing macOS + Windows Tauri app for iOS as well. I did this by running pnpm tauri ios init and pnpm tauri ios dev.

However, I run into:

Error: Cannot find module '/Users/venki/src/r2/apps/limitless/ts/src-tauri/gen/apple/tauri'
    at Module._resolveFilename (node:internal/modules/cjs/loader:1144:15)
    at Module._load (node:internal/modules/cjs/loader:985:27)

    at node:internal/main/run_main_module:28:49 {
  code: 'MODULE_NOT_FOUND',
  requireStack: []
}

Node.js v20.10.0
Command PhaseScriptExecution failed with a nonzero exit code

note: Run script build phase 'Build Rust Code' will be run during every build because the option to run the script phase "Based on dependency analysis" is unchecked. (in target 'limitless-app_iOS' from project 'limitless-app')
** BUILD FAILED **

The following build commands failed:
    PhaseScriptExecution Build\ Rust\ Code /Users/venki/src/r2/apps/limitless/ts/src-tauri/gen/apple/build/limitless-app.build/debug-iphonesimulator/limitless-app_iOS.build/Script-856DF6B869FD769F10065C61.sh (in target 'limitless-app_iOS' from project 'limitless-app')
(1 failure)
    Error command ["xcodebuild"] exited with code 65

One note is: I tried to start a new sample iOS app with create-tauri-app and that works fine. So there's definitely something odd about this project. I'll try to work on some more of the differences, and figure out a repro, but I'd love any debugging advice to point me to the right direction on how to add iOS to an existing project.

More details about exactly what I ran:

Be in the root directory (ie: the one containing src and src-tauri)
xcode-select --install
brew install cocoapods
pnpm tauri ios init
Modify vite.config.ts to add host: 0.0.0.0
I needed to modify Podfile to remove the macOS target - strangely I didn't need to do this on the sample repo.
pnpm tauri ios dev

Overall, I'd also appreciate any pointers into the Tauri repo I could investigate better. I don't really get what's trying to access gen/apple/tauri that doesn't seem like a real module to me.

I've gotten past this error, not sure if I recall what I did anymore though..

I'm now stuck at an error that seems to be this one: https://github.com/tauri-apps/cargo-mobile2/issues/291

Alright, more details incoming:

I'm able to successfully tauri ios init - but tauri ios dev fails with: Error [tauri_cli] Failed to run cargo build: command ["cargo", "build", "--package", "limitless-app", "--manifest-path", "/Users/venki/src/r2/apps/limitless/ts/src-tauri/Cargo.toml", "--target", "aarch64-apple-ios", "--features", "tauri/rustls-tls", "--lib", "--no-default-features"] exited with code 101

In order to further diagnose it, I manually run the cargo build command: cargo build --package limitless-app --manifest-path Cargo.toml --target aarch64-apple-ios --features tauri/rustls-tls --lib --no-default-features

Then, I get a more informative set of errors:

error: linking withccfailed: exit status: 1 The specific error seems to be: ld: building for 'iOS', but linking in object file (/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/macosx/libswiftCompatibility51.a[arm64][6](Overrides.cpp.o)) built for 'zippered(macOS/Catalyst)'

Which is the same as (https://github.com/tauri-apps/cargo-mobile2/issues/252, https://github.com/tauri-apps/cargo-mobile2/issues/291)

Here are more details of my exact flow:

xcode-select --install
brew install cocoapods
Update to the latest tauri-cli (2.0.0.beta.12 atm)
pnpm tauri ios init
Modify vite.config.ts to add server info, incl host and port
Modify tauri.conf.json to add bundle.iOS info - developmentTeam
Modify code to disable desktop-specific code (#[cfg(any(target_os = "macos", target_os = "windows"))])
pnpm tauri ios dev

So, I decided to try out the potential fix from: https://github.com/tauri-apps/cargo-mobile2/pull/272

I ran the following steps:

Fork tauri-apps/cargo-mobile2, cherry-pick the fix from the PR onto it, push it to a repo (https://github.com/rewindai/cargo-mobile2)
Clone tauri-apps/tauri - and within tooling/cli/Cargo.toml switch to depending on the fork version of cargo-mobile2
Install a local version of the tauri CLI via cargo install --path .
Repeat the pnpm tauri ios init and pnpm tauri ios dev flow from scratch, but using this locally built cargo-tauri that depends on the forked cargo-mobile2 instead.

That did not fix anything either, I still run into the same issue: ld: building for 'iOS', but linking in object file (/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/macosx/libswiftCompatibility51.a[arm64][6](Overrides.cpp.o)) built for 'zippered(macOS/Catalyst)

Open to any further ideas on how I'd get this working on iOS - looks like the place I'm stuck at is it seems to incorrectly be linking in something from my host platform.
