Will you support Xcode 26.3 with the iOS 26.3.1 Simulator as well? Our snapshot tests have different results on iOS 26.2 vs 36.3.1, and once you update Xcode 26.3 to use the latest simulator, there’s no way to install the 26.2 simulator anymore, creating a tough situation, where the CI environment can no longer be replicated, and test failures and fixes cannot be verified.
