Is Using AppLayout still Considered SPA?

I am enjoying developing by Vaadin, I even uploaded several on PlayStore, I just read in the PWABiulder website that IOS like Single Page Apps or SPA, any ideas or recommendations when developing for iOS? Like since the AppLayout has components as classes with routes, and each click requires a different page to be called.

thank you.,need%20an%20Apple%20Developer%20account.

The routing in Vaadin does not work by loading an entirely new page for each route. Instead, the part of the page into which the view’s contents are loaded is replaced, and the URL updated. You could say it’s an SPA masquerading as a multi-page site.
