Pardon my ignorance but can't an iOS app host a WASM runtime without being a browser? And if so it doesn't need to be an interpreted language necessarily.
Yes, it could, but then you would have re-invented React Native. But in WASM.
Yeah, but to my understanding that’s not what Shopify is doing.
I am fairly certain this is against Apple's policies. In principle you're not supposed to change the functionality of your app without review.
