Question: App in compiled using DEBUG mode about py-ios-device

[YueChen-C]

    print(rpc.call('com.apple.instruments.server.services.processcontrol', 'launchSuspendedProcessWithDevicePath:bundleIdentifier:environment:arguments:options:',
                   '',
                   'com.alipay.iphoneclient',
                   {'OS_ACTIVITY_DT_MODE': '1', 'HIPreventRefEncoding': '1', 'DYLD_PRINT_TO_STDERR': '1'},
                   [],
                   {'StartSuspendedKey': True, 'iODestinationKey': 0}).selector)

When "StartSuspendedKey" is True and the pid is returned successfully, the app is in debug mode

if HouseArrestService().send_command('com.xxxx'):

You can try using house_arrest. I don't know any other way

Hello Yue Chen, thanks a lot for sharing your approach.
I found two issues taking this mechanism:

• It tries to launch the app, but app get frozen with a black screen. No sure about how to end this launching process.
• The device need to be unlocked.

Do you think there is a way to get this information without having those issues?

Update: Even using this mechanism with an unlocked device, if the app is on debug mode, the device got stuck.
To reproduce you can try running the code first with a debug app, and then with a release one.

Example:

pid_1 = _rpc_channel.call(
        'com.apple.instruments.server.services.processcontrol',
        'launchSuspendedProcessWithDevicePath:bundleIdentifier:environment:arguments:options:',
        '',
        'com.mydebug-app',
       {'OS_ACTIVITY_DT_MODE': '1', 'HIPreventRefEncoding': '1', 'DYLD_PRINT_TO_STDERR': '1'},[],
       {'StartSuspendedKey': True}).selector

pid_2 = _rpc_channel.call(
        'com.apple.instruments.server.services.processcontrol',
        'launchSuspendedProcessWithDevicePath:bundleIdentifier:environment:arguments:options:',
        '',
        'com.any-app',
       {'OS_ACTIVITY_DT_MODE': '1', 'HIPreventRefEncoding': '1', 'DYLD_PRINT_TO_STDERR': '1'},[],
       {'StartSuspendedKey': True}).selector

After running the first launch, device got stuck until you manually kill the starting app.
It is like the instrument server is expecting another command 🤷🏽‍♂️

This definitively works fast and without issues!
You rock !
