Use xcodes instead of xcversion

[defagos]

As a developer I would like to adopt the new xcodes standard for Fastlane. This is currently not possible for Xcode beta releases.

Acceptance criteria

• The Fastfile has been updated to use xccodes instead of xcversion.
• Beta releases are supported.

Context

We already migrated to xcodes in the past (see #245) but sadly beta versions are currently not supported with this setup:

• Versions provided to xcodes command-line tool are exactly compared to version extracted from local installation information, there is currently no semantic versioning support. If an Xcode beta was installed with xcodes comparison fails since extracted installation metadata is exhaustive and does not match the required information. If an Xcode beta was installed in another way (e.g. xcinfo) then matching will work as the extracted installation metadata is less rich and passes the check (only the major / minor / patch versions are checked, basically).
• The xcodes Fastlane plugin fails to support betas. Xcodes interprets versions as exact but parses only 15 Beta 3, for example, which fails Ruby Gem versioning validation. This is a regression from xcversion since semantic versioning was supported.

Workaround

A workaround is to use xcversion during the Xcode beta phase and xcodes for releases. We can provide the same .xcode_version file to both with ~> 15.0 as version during the Xcode 15 beta phase.

Pillarbox developer tool setup should not be modified as the long-term goal is to use xcodes.

A companion issue to support Gem:Version beta version format has also be opened, with a dedicated PR.

Next steps

Of course this is a short-term workaround, as xcversion is deprecated and likely to be removed someday. Some ideas:

• Monitor the already reported issue.
• If we want to be compatible with semantic versioning we could maybe add support directly to xcodes. This would ensure that xcodes can be truly a replacement for xcversion.

Tasks

• Check status of the issues listed above.
• Upgrade xcodes if the PR submitted in Add floating version support to xcodes #442 has been approved.
• Revert to xcodes in Fastfile.
• Check that the local .xcode_version file is correctly configured.

We can still use .xcode-version and 15 as a version provided there is only a single beta of Xcode 15 installed.
