• Move both Xcode projects to the current file format (objectVersion 77) and apply Xcode 27's recommended settings to the demo project.
• Mark the two macOS-only symbols API_UNAVAILABLE instead of NS_AVAILABLE_MAC(10_9), drop the always-true OS version check in the reporter, and remove or correct comments that described code paths for OS versions TrustKit no
  longer supports.
• Replace the UIWebView section of the getting started guide with a WKWebView example that validates off the main thread, and add that example to both demos with UI tests for a pinned page that loads and one that is blocked.

Nothing blocking. The comments below are optional suggestions. There is no need to push a fix for them before merging.

Besides the inline finding, I checked two more things and found no problem in either:

• The new API_UNAVAILABLE(ios, tvos, watchos, visionos) markings: every reference to TSKTrustEvaluationFailedUserDefinedTrustAnchor and kTSKIgnorePinningForUserDefinedTrustAnchors is already inside #if !TARGET_OS_IPHONE. That covers TrustKit.m, TSKPinningValidator.m, parse_configuration.m and TSKReporterTests.m, so iOS and Mac Catalyst builds still compile.
• The removed nil check in TSKBackgroundReporter.m: nothing earlier in the init sets _appPlatformVersion, so the behavior is the same as before.

Extended reasoning...

One demo-app nit was reported inline. I also checked the library-side availability changes and the reporter change, and neither has a problem.

🔵 Needs a closer look

WebKit authentication changes need cancellation-handling corrections and Apple-platform validation before final human approval.
