Done.

2. Edit Tweak.xm as follows:

extern "C" NSString *CTSettingCopyMyPhoneNumber(void); // From CoreTelephony

%hook PreferencesAppController

• (BOOL)application:(id)arg1 didFinishLaunchingWithOptions:(id)arg2
  {
  BOOL result = %orig;
  NSLog(@"iOSRE: my number = %@", [CTSettingCopyMyPhoneNumber() autorelease]);
  return result;
  }
  %end

3. Edit Makefile and control

The finalized Makefile looks like this:

export THEOS_DEVICE_IP = iOSIP

export ARCHS = armv7 arm64

export TARGET = iphone:clang:latest:8.0

include theos/makefiles/common.mk

TWEAK_NAME = iOSREGetMyNumber

iOSREGetMyNumber_FILES = Tweak.xm

iOSREGetMyNumber_FRAMEWORKS = CoreTelephony # CTSettingCopyMyPhoneNumber is from here

include $(THEOS_MAKE_PATH)/tweak.mk

after-install::

install.exec "killall -9 Preferences"

The finalized control looks like this:

Package: com.iosre.iosregetmynumber
