AG::LayoutDescriptor::Builder::Emitter中的SwiftUI崩溃

Question

我正在尝试找出仅在iOS 13.2 - 13.3设备上导致崩溃的问题：

3
AttributeGraph
AG::precondition_failure(char const*, ...) + 192
4
AttributeGraph
AG::LayoutDescriptor::Builder::Emitter<AG::vector<unsigned char, 512ul> >::operator()(AG::LayoutDescriptor::Builder::EqualsItem const&) + 214
5
AttributeGraph
AG::LayoutDescriptor::Builder::Emitter<AG::vector<unsigned char, 512ul> >::operator()(AG::LayoutDescriptor::Builder::EqualsItem const&) + 124
6
AttributeGraph
AG::LayoutDescriptor::Builder::commit(AG::swift::metadata const*) + 152
7
AttributeGraph
AG::LayoutDescriptor::make_layout(AG::swift::metadata const*, AGComparisonMode, AG::LayoutDescriptor::HeapMode) + 320
8
AttributeGraph
AG::(anonymous namespace)::LayoutCache::drain_queue(void*) + 152

有没有人知道是什么导致了这个问题？

更新:通过使rootView符合Equatable协议，我修复了这个问题。
