I don't even want to start on "PWAs work more seamlessly than native". I just cannot take person making such claims seriously.
Consider, for example, the interaction between generics in structs and classes, and protocols with associated types, and why you have to make stupid type-erasing wrappers like 'AnyObject' and so forth.
JS barely even has types at all, let alone generics. There's a lot less to go wrong there :-)
