While trying to download dependencies via Carthage in our project with Xcode 12 beta 5 and 6 version. I am getting dylib linking error as below:

ld: building for iOS Simulator, but linking in dylib built for iOS, file 'Carthage/Build/iOS//XXXFrameworkName.framework/XXXFrameworkName' for architecture arm64

It is working as expected in below Xcode 12 version(i.e Xcode 11.x).
Could you please help on this? Is this a Xcode 12 beta version issue?

The new MacBooks will have ARM processors. Your libraries will need an appropriate "slice" to support running in the simulator on these new MacBooks.

What I am trying to figure out is what is this slices architecture so I can rebuild these dependencies? (It doesn't appear to be ARM64)

The appropriate "slice" would be a version of "XXXFrameworkName" that is ARM64 and compiled for the iOS Simulator. You have ARM64, but compiled for the iOS Platform. I'd imagine that you will have 2 ARM64 binaries in one static library.

Hi,

Same problem here with an 3 years old iOS project I've been working on for 3 days with a MacBook Pro M2 :

Building for iOS Simulator, but linking in dylib built for iOS, file ... for architecture arm64

If I understood well, it is because the CocoaPod library isn't compatible with the ARM processor.

I tried to upgrade the library from CocoaPod but same problem, CocoaPod isn't compatible with ARM processor, I need to upgrade Ruby and so on...

But all the projects libraries exist as a Git repo (I have to check) so if I migrate from CocoaPods to Swift Package Manager (which what it will have to be done anyway) as described in many articles, it will be fine right ?

Thx.
