Bug: The conditional compilation directives for SentryFramesTrackingIntegration are inconsistent. It's enabled for macCatalyst in Integrations.swift but disabled in its implementation and protocol conformance, causing a build failure.
_{Severity: CRITICAL | Confidence: High}

🔍 Detailed Analysis

There is a conditional compilation mismatch for macCatalyst builds. The Integrations.swift file attempts to register SentryFramesTrackingIntegration<SentryDependencyContainer> when targetEnvironment(macCatalyst) is true. However, the class definition for SentryFramesTrackingIntegration and the FramesTrackingProvider protocol conformance for SentryDependencyContainer are not compiled for macCatalyst, as they are missing targetEnvironment(macCatalyst) in their #if directives. This discrepancy will lead to a Swift compilation error on macCatalyst builds because the compiler will be unable to find the specified type and protocol conformance.

💡 Suggested Fix

Add targetEnvironment(macCatalyst) to the conditional compilation directives in SentryFramesTrackingIntegration.swift and SentryDependencyContainer.swift to match the directive in Integrations.swift. This will ensure the frames tracking feature is consistently compiled across all necessary files for macCatalyst builds.

Potential issue: There is a conditional compilation mismatch for macCatalyst builds. The
`Integrations.swift` file attempts to register
`SentryFramesTrackingIntegration<SentryDependencyContainer>` when
`targetEnvironment(macCatalyst)` is true. However, the class definition for
`SentryFramesTrackingIntegration` and the `FramesTrackingProvider` protocol conformance
for `SentryDependencyContainer` are not compiled for macCatalyst, as they are missing
`targetEnvironment(macCatalyst)` in their `#if` directives. This discrepancy will lead
to a Swift compilation error on macCatalyst builds because the compiler will be unable
to find the specified type and protocol conformance.
