Xcode 10 seems to break com.apple.commcenter.coretelephony.xpc

Question

I have upgraded to Xcode 10 on High Sierra and now the Rewarded Ad example project from AdMob complains that com.apple.commcenter.coretelephony.xpc is not working correctly.

Is there a new entitlement that I have to enable? I am searching for hours without any clue.

UPDATE: This only happens from the simulator. On the device it works fine. They must have added a new restriction.

I got the same problem with AWS Cognito, did you solve the problem? — YoanGJ, Oct 12 '18 at 17:31
Oh ok, in my case I realized that this error was happening only with the simulator but not with a real device. EDIT: I just saw your edit about the simulator thing — YoanGJ, Oct 13 '18 at 13:33
Yes, it's annoying as you have to use your device for testing and can't use the simulator anymore. — Houman, Oct 13 '18 at 14:27
I no longer have High Sierra to test this. I accept your answer in good faith. :) Thanks — Houman, Mar 11 '19 at 19:14

Running this in Terminal made it go away:

xcrun simctl spawn booted log config --mode "level:off"  --subsystem com.apple.CoreTelephony

It simply sets a config for the simulator to have no ("off") logging for the subsystem com.apple.CoreTelephony. It's much better than rejecting all OS messages as some of them (I think auto layout warnings also belongs to it) are really useful – Lucas van Dongen Feb 27 '19 at 14:40

@ChikabuZ did you install the command line utilities? If not, let me know if it helped. If you already did, let me know as well. – Lucas van Dongen Apr 11 '19 at 15:34

@DepartamentoB I installed "Command Line Tools for Xcode" but I receive the same error. – ChikabuZ Apr 12 '19 at 08:37

@ChikabuZ you need to set the location of command line tools in Xcode. https://stackoverflow.com/questions/29108172/xcrun-unable-to-find-simctl – Pablo May 28 '19 at 19:32

Can't believe this is still an issue on Xcode 11+. How Apple devs don't get annoyed with this themselves enough to fix it is beyond me. – Aaron Nov 13 '19 at 19:34

Is there a way to turn it back on? "level:on" is an invalid mode – Chucky Apr 13 '21 at 11:27

Well it's working on both the simulator and device in Xcode 10.2.

Add CoreTelephony.framework (Optional)

Executing the following command in Terminal:

xcrun simctl spawn booted log config --mode "level:off" --subsystem 
com.apple.CoreTelephony

From the Xcode menu open: Product > Scheme > Edit Scheme

On your Environment Variables set OS_ACTIVITY_MODE = disable
Restart simulator

for me OS_ACTIVITY_MODE = disable worked. Xcode 10.3, Mojave – ashishn Sep 03 '19 at 18:11

No it does not work, it does not show debug messages. So layout errors does not appear, either. so sad. – Burcu Kutluay Oct 14 '19 at 08:46

Just the simctl booted log config command was enough for me. Turning off OS_ACTIVITY_MODE will hide these along with everything else (including NSLogs) which hides too much. – Carl Lindberg Feb 19 '20 at 01:33
Worked for me! (just running xcrun in the terminal was not enough) – Peter Jun 20 '20 at 19:32

I found a workaround restarting the simulator.

For those who are experiencing this issue in real devices, linking CoreTelephony.framework to the project fixes the problem.

It does not fix it for the simulator, though.

Run this in Terminal,

to disappear those log messages

  xcrun simctl spawn booted log config --mode "level:off" --subsystem com.apple.CoreTelephony

to appear those log messages:

  xcrun simctl spawn booted log config --mode "level:default"  --subsystem com.apple.CoreTelephony

Possible mode levels: off, debug, info, default

Additional informations:

It's possible to set the level for "com.apple.CoreTelephony" subsystem on the system level with:

sudo log config --mode "level:off"  --subsystem com.apple.CoreTelephony

Silencing those logs with the OS_ACTIVITY_MODE flag will silence other system logs.

From the Xcode menu open: Product > Scheme > Edit Scheme

On your Environment Variables set OS_ACTIVITY_MODE = disable

For people facing this issue when building on real devices, turning on the wifi on the device fixed the problem. This seems to trigger when cellular is being used in stead of wifi.

I was having the same issue, and this is how I solved it: Go to the tab Build Phases and search for Bundle React Native code and images and below shell input add:

export NODE_BINARY=node ../node_modules/react-native/scripts/react-native-xcode.sh

This worked for me with Xcode 11.3.1

Hope this helps someone!
