Cordova Mobile App for iOS is not communicating with the server

Question

I am doing the Meteor.js tutorial app available at https://www.meteor.com/tutorials/blaze/creating-an-app. The app starts on iPhone without a problem but it does not have any server/db data on it. It seems it is not communicating with Meteor server running on my Mac. The iPhone is connected with with Mac via an USB cable.

The Cordova version used by Meteor is 4.3. I have iOS 10.11 on the Mac, iOS 10.2 on the iPhone and Xcode 8.2. The Meteor version is the latest; 1.4.4.2 with all packages up-to-date.

I am appending Xcode runtime log below. What can be the reason? Or, What should I do to understand the root cause of the problem? P.S: I noticed the log at the end "Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates." Does this log give some info about the reason?

Answer 1

Make sure that you iPhone and computer are on the same network. Reference to the Doc here in "Connect to Server" chapter.
