Update macOS self-hosted pipeline to the nightly toolchain

[bkhouri]

Is it reproducible with SwiftPM command-line tools: swift build, swift test, swift package etc?

• Confirmed reproduction steps with SwiftPM CLI. The description text must include reproduction steps with either of command-line SwiftPM commands, swift build, swift test, swift package etc.

Description

The macOS self-hosted pipeline is running Swift 5.9.2. This prevents the use of Swift Testing, and is currently blocking, at a minimum, the following PRs (which are currently marked as draft pending resolution if this issue):

• Test: Convert more tests to Swift Testing #8100
• Test: Add platform helpers #8099
• Tests: Convert some tests BasicsTests to Swift Testing #8093
• Tests: Convert some WorkspaceTests module tests to Swift Testing #8092

It would be ideal to update the macOS self-hosted pipeline toolchain version such that it uses the same version across all pipelines.

Expected behavior

A toolchain version that supports Swift Testing is in use by all pipelines.

Accessing the last successful build will show Swift 6.x in use.

Actual behavior

The self-hosted macOS pipeline is still using 5.9.2.

Created a new pull request job to support nightly toolchain testing.

@swift-ci Please test nightly self hosted

The self-hosted macOS pipeline using the nightly toolchain is now a required pipeline.

Closing this issue as it has been fixed.
