Sharing some findings.
We just got done migrating to Xcode 15.1
- With Intel Gen 2 and x86_64 simulator - All of our Unit and Snapshot tests are passing.

- With M1 Medium and x86_64 simulator using Rosetta2 - Our Snapshot tests pass, but our Unit tests seem to be randomly failing due to tests not asserting within the mentioned timeouts.

- With M1 Medium and arm64 simulator - All of our Unit and Snapshot tests are passing.

Looks like running the tests on x86_64 simulator using Rosetta2 seems to be slower in general.
Anybody else notice similar?
