iOS: Unexpected CFNetwork logs on `tns run ios` as of {N} 4.0.0

Tell us about the problem

After upgrading to {N} 4.0.0, a ton of logs normally only visible using tns device log are showing up on the console during a tns run ios. Sample output from tns run ios:

TIC TLS Event [1:0x1c0564440]: 1, Pending(0)
TIC TLS Event [1:0x1c0564440]: 2, Pending(0)
TIC TLS Event [1:0x1c0564440]: 11, Pending(0)

TIC TLS Event [2:0x1c436e940]: 14, Pending(0)

Sample output from tns device log:

The device logs are consistent with output from running on {N} 3.4.1 (the CFNetwork logs themselves are not new). The new behavior is that they show up when running tns run ios. In the past, only console.log output would show when running tns run ios, like so:

CONSOLE LOG file:///app/src/common/services/logging/console.target.js:16:46: App Service Constructed -> Platform Target = mobile
CONSOLE LOG file:///app/src/common/services/logging/console.target.js:16:46: Connectivity: Connection type changed to wifi.
CONSOLE LOG file:///app/src/common/services/logging/console.target.js:16:46: Connectivity Initialized

There appears to be an issue with the logs that are “let through” to the console.

Unfortunately, this problem seems to persist in {N} 5.x with Firebase plugin 7.7.

The OS_ACTIVITY_MODE setting did not seem to have any effect on my console output…at least when running the app with tns run.

It seems we’ve validated that the issue is reproducible. Any further thoughts on a fix? The challenge is that these verbose network/TCP logs make it virtually impossible to use console log output, especially if an app is making lots of network calls.

[toddanglin]

FWIW…as a “dirty” hack around the issue, you can just pipe the output of the tns run command thru a grep filter. It doesn’t work well with LiveSync, so not a perfect solution, but can help get rid of the noise if you’re looking for specific console messages.

Example: $ (tns run ios --device 1) | grep '^CONSOLE'

Will only output messages that were explicitly console logged. Hope that helps.
