Dioxus 0.7.3 serving iOS mobile on Intel Mac fails

[petewatts]

Problem

Attempting to run dx serve --ios using dioxus 0.7.3 on an Intel Mac fails. I admit i'm completely new to rust and dioxus so no doubt it's something I'm doing wrong, but I just can't figure out what. Originally was trying to get it working with fullstack after following the examples, but reduced it to just mobile with no fullstack and still can't build. Many months ago I tried getting this working with Dioxus the previous 0.6.3 version but no luck there either.

Running dx serve --ios --verbose with the vanilla/basic app returns these errors:

18:43:43 [dev] Executing cargo for ios using x86_64-apple-ios 
18:44:48 [cargo] error: linking with `cc` failed: exit status: 1

I think the problem is relating to the use of "-target" "x86_64-apple-ios10.0.0-simulator" which might not play nicely with Xcode 26.0, or that it's using iPhoneOS.sdk instead of iPhoneSimulator.sdk, but that's not based on any actual knowledge just some searching. .Honestly, i'm guessing 😂 I've tried to locate any remnant leftover Xcode old config. Is there anything else I can do to help it find the right iOS version to build against?

I have run exactly the same commands on an Apple Silicon Mac and everything worked as expected. (unfortunately may main machine is Intel currently so really need to be able to develop on that)

Any help or pointers to resolve this would be gratefully received.

Steps To Reproduce

Steps to reproduce the behavior:

• On an Intel X86 Mac:
• dx new ios_app
  • Which sub-template should be expanded? Bare-Bones
  • Do you want to use Dioxus Fullstack? false
  • Do you want to use Dioxus Router? false
  • Do you want to use Tailwind CSS? false
  • Do you want to include prompts for LLMs? false
  • Which platform do you want DX to serve by default? Mobile
• cd ios_app
• dx serve --ios

Expected behavior

Project compiles, iOS simulator starts, app is loaded and runs in simulator.
