Hey @hirophan 

We’ve seen that Xcode error a few times before with other iOS developers, and each case seems to have been solved in different ways:

• “Packages don't allow customization of the architectures to build for and will always build with default settings for "Build Active Architecture Only", which has the consequence that when building in debug mode, you'll only get an arm64 build of any packages.”

• (XCode 11) https://stackoverflow.com/questions/56957632/could-not-find-module-for-target-x86-64-apple-ios-simulator
• (XCode 12) https://developer.apple.com/forums/thread/123614
• (XCode 12) Something very similar was even reported as an issue and closed after a few troubleshooting questions in our flutter SDK: https://github.com/customerio/customerio-flutter/issues/41#issuecomment-1523666322

We believe that this is likely more closely related to the specific device you're building on and/or your current xCode version/settings. 

• Can you share what Mac and Mac OS are you using to build your app? (e.g. Are you developing on Apple Silicon or an Intel chip?)
• What XCode version are you using? (You can get this by running xcodebuild -version in your CLI)

@Jordan Thanks for your suggestion but I tried all your links but nothing worked.

I’m using Macbook Pro, Mac OS 14.1.1 (23B81). Chip M2 Pro. XCode 15.0.1 (15A507)

Hey @hirophan 
 

If you've tried Jordan's suggestions and the error persists, please try the following:

1. Delete the derived data.
2. Restart Xcode.
3. Reinstall the SDK (SPM/CocoaPods).

@aman Thanks for your reply. I tried to do it many times but got no luck.
