The xcode has been configured differently across repos, platforms, and targets. Some examples:

• platform property: xcode: 14e222b
• platform dependency: {"dependency": "xcode", "version": "14e222b"}
• target xcode dependency: {"dependency": "xcode", "version": "14e222b"}
• target osx_sdk property: $flutter/osx_sdk : >- { "sdk_version": "14e222b" }
• target runtime property: runtime_versions: >- [ "ios-16-4_14e222b", "ios-16-2_14c18" ]
• osx_sdk property in engine v2 config: "$flutter/osx_sdk": { "sdk_version": "14e222b" }

This bug tracks consolidating all these configs into a single one config:

properties:
      $flutter/osx_sdk : >-
        { 
          "sdk_version": "14a5294e",
          "runtime_versions":
            [
              "ios-16-0_14a5294e"
            ]
        }
