Apple mobile test failures on runtime-extra-platforms

[kotlarmilos]

Description

There are several types of failures encountered on extra-platforms since dotnet/xharness#1416 was integrated into runtime. That change upgraded the mlaunch version and introduced result copying from device/simulator to the host machine to mitigate TCP tunnel limitations on iOS 18.x.

Example build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1095577&view=results

iOS/tvOS failures

A subset of machines has been upgraded to iOS 18.5, and tests running on these machines are failing with the following error:

Error: If you are targeting a data container, you must specify a username.
[18:27:04] dbug: Usage: devicectl device copy from --device <uuid|ecid|udid|name> --source <source> [--destination <destination>] [--user <user>] --domain-type <domain-type> [--domain-identifier <domain-identifier>] [--verbose] [--quiet] [--timeout <seconds>] [--json-output <path>] [--log-output <path>]

Action points:

• Fix the issue in XHarness and flow the fix into runtime
• Reduce logging from XHarness/mlaunch
• The 18.1 version passed in previous PRs; ensure the same machine queue is used in XHarness tests
• AppleTV queue includes machines with higher OS version #117807
• AppleTV queue fails to locate devicectl in PATH #117805
• tvOS and iOS scouting queues can't find device xharness#1441

iOS/tvOS simulator failures

Some tests are failing due to launch-timeout issues. These machines are already on 18.x.

Action points:

• Determine if the failures are test-specific or machine-specific
• Check if mlaunch has changed timeout behavior for simulators

MacCataylst failures

After tests complete successfully, Helix reports the following error:

symbol not found in flat namespace '_PyType_GetName'

Action points:

• MacCatalyst job fails due to python version mismatch #117804

@missymessa we need your help. Could you please confirm the current state of the apple mobile queues? Specifically which version is being used in each queue? Is the version uniform across all machines within each queue?
