Disable system log in TNS 4 console

Hello,

I’am using NativeScript Vue for developing my app, however, since upgrading to TNS 4, the tns console output log is too much verbose with system logging messages. Is there any way to disable all these logs and print only application level logs ?

Every time I run the app, it’s impossible to see my debug log since there are a lot of system logs, for example:

AVAudioSession.mm:323:HandleRouteChange: Posting AVAudioSessionRouteChangeNotification.

Issue occurs since TNS 4.0

• Both iOS/Android

To recreate the issue

• Execute command tns [run|debug] [ios|andorid] for any NativeScript project.

Thank you for any help.

The only workaround I have so far is to manually edit ios-log-filter.js by adding additional filtering conditions:

preFilter(data, currentLine) {
        return currentLine.length < 1 ||
            currentLine.indexOf("WebProcessProxy") !== -1 ||
            currentLine.indexOf("ProcessAssertion") !== -1 ||
            currentLine.indexOf("ProcessThrottler") !== -1 ||
            currentLine.indexOf("locationd") !== -1 ||
            currentLine.indexOf("SecTaskCopyDebugDescription") !== -1 ||
            currentLine.indexOf("NativeScript loaded bundle") !== -1 ||
            (currentLine.indexOf("assertion failed:") !== -1 && data.indexOf("libxpc.dylib") !== -1);
}

This is obviously a hack (and still misses a ton of system logs), but at least (for now) I can filter out the noisiest system logs so I can see more of my own.

EDIT:

This works better…

preFilter(data, currentLine) {
        return currentLine.length < 1 || currentLine.indexOf("CONSOLE") === -1 ;
}

I’m having the same issue, @speigg @GrEg00z where is the ios-log-filter.js file located?
