[bug] version '-sim' in target triple 'arm64-apple-ios13.0-simulator-sim' is invalid

[raptoria]

Describe the bug

After updating to the latest IOS, the tauri ios dev command is failing.

The error after running tauri ios dev command:

duxmedical-aahqqdcrqlepwtdchjpelwtniybn/Build/Products/debug-iphonesimulator/duxmedical.app/__preview.dylib
clang: error: version '-sim' in target triple 'arm64-apple-ios13.0-simulator-sim' is invalid

My xcode looks like this

Are there supposed to be 2 options for each device? They all lead to this error.

Reproduction

repro link: https://github.com/raptoria/tauri-repro

Choose 13 (iPhone 16)

Expected behavior

IOS Simulator should run

Additional context

I get the same error when I create a brand new tauri project from scratch using

pnpm create tauri-app

[petaltank]

I encountered the same issue starting yesterday. I also had just installed all of the 18.4 simulator devices. I uninstalled all of them (I think the duplication is a temporary thing as they bridge 18.3.1 and 18.4?), and I also tried starting a brand new project. I'm using cargo/rust so this is not exclusive to pnpm either.

[jfahrenkrug]

I'm getting the same error on my end as well. I'm on the newest Xcode (16.3) and I'm using npm and getting the same error.

[ShaneTsui]

Same issue after upgrading to Xcode 16.3. Downgrading to Xcode 16.2 fixed it for me.

[lucasfernog]

I can reproduce. I'll see what has changed

[lucasfernog]

I couldn't figure out yet ;(

[shusann01116]

I'm not sure, but the compiler's updates can be related as documented in the patch note

Clang now defines TARGET_OS_* conditionals as built-in macros based on the provided target triple. This extension can be disabled with the flag -fno-define-target-os-macros. (111414452)

[plitarko]

Same here: This broke development for all my tauri projects

[daveycodez]

Is it only broken for simulator? Or for devices as well

[plitarko]

Only for simulator

See (possible) related issue in cargo-mobile2.

See related issue in cargo-mobile2.

I don't think that's related
