Hey everyone! I'm trying to build in XCode, but each time I go through and try to fix something, I keep getting the same error:

The i386 architecture is deprecated. You should update your ARCHS build setting to remove the i386 architecture.

I've been searching around online and forums, but can't quite find what I need to do to fix this. Could one of you please spell it out for me? I need to get this working for a master's project. Thanks!

You should better clarify the version of Xcode and which platform your app is targeting. iOS? MacOS? Or some other?

Generally, choose Build Settings tab in the project editor and put ARCH in the search bar, then you can find a setting titled Architectures.

But if your project includes such setting as i386, your project would be so old and you might find many difficulties even after you fixed it.

Thanks for showing the info. You can edit ARCH (Architectures) as shown in my previous reply in Xcode 12.3.
