Easily reproduced with a new empty project. Add the device and console plugins,
and the iOS platform. Then in the onDeviceReady function put a console log
statement, followed by a delay loop of about 100ms. Run it on the 6S simulator.
Console log never executes. CPU pegs. Reduce the delay to about 50ms and
everything works great.
was (Author: michaelstanford):
I experienced this issue too, new in Cordova 6.0.0. It freezes on phones, and
pegs the CPU on the simulator.
It does seem to be some kind of race condition: when the onDeviceReady function
is short and fast, the issue doesn't occur. When the onDeviceReady function
takes a sufficient time (critical time varies from run to run), it fails to
complete.

> Key: CB-10530
> URL: https://issues.apache.org/jira/browse/CB-10530
> Project: Apache Cordova
> Issue Type: Bug
> Components: iOS
> Affects Versions: 6.0.0
> Environment: OSX El Capitan 10.11.3, XCODE (7.2.1), iOS 9.2.1,
> cordova 6.0.0, ionic 1.7.14
> Reporter: Florian Krüger
> Priority: Critical
> Labels: triaged
> Attachments: Instruments.trace.zip

>
> * Installed the "ionic start myApp sidemenu" example application
> * Start XCODE (7.2.1)
> * Start the app by clicking the run button from xCODE
> * The app probably starts as expected.
> * Repeat the start process until the app freezes.
> The app sometimes freezes completely. If this happens you cannot do anything
> with the app (you need to push the home button and close the app via task
> manager). I had the same issue for another more complex app.
> The CPU stays at around 99% workload.
> I made a snapshot of the profiler (Instruments)
