Swift Testing iPad CI Tests Fail

[max-rosenblattl]

Describe the bug
Snapshot tests for iPad devices fail when using Swift Testing in CI environments only and not locally. Due to the missing attachment support for Swift Testing, it's not possible evaluate why the tests fail. Generally, curious if anyone experienced a similar behaviour.

To Reproduce
Setup a GitHub test runner (configuration below) and execute any snapshot test using an iPad test config.

    @Test("Reverse Label Style")
    func reverseLabelStyle() {
        let label = SwiftUI.Label("100 %", image: "battery.100")
            .labelStyle(.reverse)

#if os(iOS)
        assertSnapshot(of: label, as: .image(layout: .device(config: .iPadPro11)), named: "ipad-regular")
#endif
    }

Expected behavior
Tests that pass locally should pass on the CI as well.

Environment

swift-snapshot-testing version 1.18.4
Xcode 16.3
Build version 16E140
Apple Swift version 6.1 (swiftlang-6.1.0.110.21 clang-1700.0.[13](https://github.com/StanfordSpezi/SpeziViews/actions/runs/15121228869/job/42503853058#step:5:14).3)
Target: arm64-apple-macosx15.0
env.selfhosted: true

{ platform:iOS Simulator, arch:arm64, id:D7ACB328-69BF-46BF-8BBF-F640A7853A03, OS:18.5, name:iPhone 16 Pro }

Additional context
Generally, more interested in whether anyone else experienced this behaviour only in CI environments with tests passing locally.

I am wondering if we are experiencing the same issue: #1001

If I do it using XCTestCase it works fine SwiftTesting it starts failling.

Here is a screenshot from my CI:
