x86 is rarely used nowadays, especially in the development workflows for iOS development. Apple Silicon machines are mostly used and the devices are arm64.
It would make sense to have a default behavior of the cache command to only build for ARM/Apple Silicon architecture. It would still make sense to have an option to allow building for x86.

Fully agree 💯
We’ll be changing the default to only build for the active architecture and still allow for building for non-active architectures by adding a new option:
```auto
tuist cache --architectures x86_64
tuist cache --architectures x86_64,arm64
tuist cache --architectures arm64 # This will be the default on ARM machines
```
