Does anyone know the runtime performance I can expect from the anchor(for:) and node(for:) methods on ARSCNView? I don't see this documented. Would it be safe for me to assume this is a constant-time lookup? Would I need to assume this is a linear-time operation that scales up with the number of nodes and anchors active?
Is it my responsibility to do my own bookkeeping if I want to look these relationships up in constant-time?
