Struct Namespace 

pub struct Namespace(/* private fields */);

A @Namespace, shared between the views that should match.

namespace_id mints a fresh id on every call, because SwiftUI’s counter advances on each read. That is right for a modifier that scopes one subtree and wrong for one whose whole purpose is pairing: two views handed separately-minted ids are in different namespaces and can never match, so matchedGeometryEffect built the correct Swift value and did nothing. The _in variants below take one of these instead, which is how SwiftUI spells it — @Namespace var ns once, in: ns at each use.
