In the nearish future it will be. Expo modules are slated to *soon* support SwiftUI.

Yeah I’m getting my Swift skills ready for when that lands :)

I've been playing with them for a bit now, mainly through submitting expo SDK PRs. Being able to add native code using Swift or Kotlin over....😬obj-c....is awesome. Once the SwiftUI support lands (hopefully SDK 50?) things will be great!
