+/**
+ * Xcode 26 + `use_frameworks! :linkage => :static` makes the main app target
+ * auto-link SwiftUICore directly (SwiftUI was split into SwiftUI + SwiftUICore on
+ * recent SDKs, and the SwiftUI pods' object files carry a `-framework SwiftUICore`
+ * autolink directive that flows into the app link). The linker then rejects it:
+ *   ld: cannot link directly with 'SwiftUICore' because product being built is
+ *       not an allowed client of it
+ * Weakly linking SwiftUICore on the app target bypasses the allowed-client check;
+ * the symbols still resolve at runtime via SwiftUI's re-export.
+ *
+ * Scoped to `com.apple.product-type.application` ONLY — it must not touch the
+ * tvOS TopShelf app-extension (which legitimately links SwiftUI); applying the
+ * flag there breaks that target.
