No longer able to deploy to iOS. Why?

I’ve made a few small adjustments to my app to get rid of a few glitches that were introduced when upgrading to 1.6.1. The app is running without a hitch on galaxy in all browsers.

Now, deploying for iOS also works… occasionally. I do the following:

meteor run ios-device --mobile-server https://myapp.meteorapp.com/

Then, when building for a device in Xcode, the app fails to load… often, but not always. When it fails, this is what the console reports:

...

This happens on the splash screen. And, it happens in the iOS simulator, when running on an attached iOS device, and, after pushing it to iTunesConnect, on the version that’s available through TestFlight (although, there, I can’t of course confirm it’s the same problem, the app just never gets past the splash screen).

There’s no indication there’s an actual issue with my connection, either inside the iOS simulator or on my computer.

What is causing this?

I ended up reinstalling Meteor. At the moment, this issue no longer occurs.
