We're changing the way we provide Xcode versions to our macOS stacks users.
Previously, each Xcode version on Bitrise was available on an isolated virtual machine (VM) image. This caused long queue times during migration between Xcode versions, technical limitations introduced by Apple, and generally a slow and costly migration.
To solve this, Bitrise will provide multiple versions of Xcode per VM image. This will enable you to get the best migration experience possible, whilst ensuring builds can start as close to immediate as possible.
