The Bitrise team is updating its simulator runtime policy to align with Apple's minimum requirements and supported SDKs for Xcode, which will inevitably lead to the deprecation of older versions of the Xcode simulator runtimes. The new policy prioritizes newer versions of Xcode and ensures that the latest compatible simulator runtime is available across all stacks. This approach means that older simulator runtimes will be phased out as the oldest actively updated version of Xcode increases, while also supporting the most recent versions of iOS simulator runtimes prior to the oldest major version included in the stacks. The policy applies to both iOS, tvOS, and watchOS simulator runtimes, with the next most recent runtime being made available where compatible.
