Answer 1

Problem

The following or a similar error message occurs when adding the console plugin to the ios platform (or after reinstalling) via Command-line Interface:

"CDVPlugin class CDVLogger (pluginName: Console) does not exist."

Solution

Open your Xcode project and go to the tab "Build Phases". Now open the drop-down named "Compile Sources". Click on the "+" sign at the end of the list and add "CDVLogger.m" or any other missing source.

You need the debug console plugin added to your project:

phonegap local plugin add https://git-wip-us.apache.org/repos/asf/cordova-plugin-console.git

In later versions of phonegap/cordova, to add the debug console plugin in your project:

cordova plugin add org.apache.cordova.console

I've found JSconsole.com extremely useful for remotely capturing console logs from mobile devices.

Heres how you set it up:

1. In you apps index.html, Include(change the ID):

     <script src="http://jsconsole.com/remote.js?<MAKE UP SOME UNIQUE ID>"></script>
   

2. On your computer, Go to jsconsole.com and type :listen <YOUR UNIQUE ID>

Open your app on your mobile device, you will see console logs on your computer.

I found GapDebug really useful. Unlike anything else [cough cough weinre], it let's you console log from your local app

Answer 5

If you have installed the Cordova console-plug-in, then when you run your app:

phonegap run iOS

you will find the logs at:

[your project dir]/platforms/ios/cordova/console.log

for IOS. All console logs show up as expected.

Besides adding the Console plugin I have another assumption why it might not work:

console.log in Phonegap is called asynchronously thus if a future call fails, the whole function fails and all log calls within are swallowed.

  receivedEvent = function( id ) {
    alert( 'This message is displayed because alert is called synchronously ')
    console.log( 'This will not be displayed in Phonegap only in browser' )
    callingAFunctionWhichDoesNotExist()
    console.log( 'This will neither be displayed in Phonegap nor in browser' )
  }
