+**Known automation limitation — SwiftUI Text links:**
+Simulated taps (via XcodeBuildMCP or any simulator automation tool) do not trigger gesture recognizers on SwiftUI `Text` views with inline `AttributedString` links. Taps report success but have no effect. This is a platform limitation — inline links are not exposed as separate elements in the accessibility tree. When a tap on a Text link has no visible effect, prompt the user to tap manually in the simulator. If the target URL is known, `xcrun simctl openurl <device> <URL>` can open it directly as a fallback.
