Any way to debug apps in Ionic View?

I have an app that works fine in the browser.
I’m able to successfully deploy my app with ionic cordova run to both iOS and Android.
I wanted to try testing with Ionic View as it seems the simplest solutions “download from app store, no UDIDs, etc.”.

I added Ionic View to both my Android and my iOS devices.
Android worked right away.
But iOS just gave me a white screen.
Is there any way to find out why?
