bug: Barcode Scanning plugin failing to build on simulator for fresh Ionic project about capacitor-mlkit

[JaapWeijland]

So I found how I can fix this by altering the ionic cap ios run command of capacitor. In node_modules, in the file @capacitor/cli/dist/ios/run.js, change the line that says id=${target.id} to id=${target.id},arch=x86_64. This will force capacitor to build the project using Rosetta, which is needed to build a project using this plugin for a simulator.

I'm not sure if this is a problem with this plugin, or a missing feature of capacitor to allow for building using Rosetta, especially now that this option to do this as a configuration within Xcode has been removed by Apple.

This should fix your issue: https://capawesome.io/blog/troubleshooting-capacitor-ios-issues/#could-not-find-module-capacitor-for-target-x86_64-apple-ios-simulator

No need to use Rosetta. Feel free to take a look at the official demo app for reference: https://github.com/robingenz/capacitor-mlkit-plugin-demo/blob/main/ios/App/Podfile

Thanks for your response. I already tried this, and unfortunately, it does not work. I added the lines to the reproduction repo as well, so you can see what I did and try it out yourself if you want.

Edit: actually, I tried running the demo app, but that app errors out with the same error as well:

SwiftEmitModule normal x86_64 Emitting\ module\ for\ App (in target 'App' from project 'App')

Repro path:

1. Clone project
2. ionic cap sync
3. ionic cap ios run

Added Ionic versions to opening post:
ionic --version: 7.2.0
ionic cap --version: 7.2.0 (not sure if this matters)

Okay, now I was able to reproduce your problem. But only in the simulator, on a device it works without problems.
This is how i fixed it: robingenz/capacitor-mlkit-plugin-demo@febf323

Works! Thanks alot. Since from now on all newcomers will pretty much experience what I've experienced when they want to run their app on a simulator, it might be handy to add this to the documentation or FAQ or something similar. Anyway, thank you very much for helping out!

I'm glad that it is now working. I have updated the blog post.
