When I am running application on simulator or device and try to use PO command during debug. Xcode is throwing error instead of printing value. It is happening after I have updated Xcode 12.
error: virtual filesystem overlay file
/all-product-headers.yaml' not found
error: couldn't IRGen expression. Please check the above error messages for possible root causes.
What is the solution for this ?
Any help would be appreciated.
Go to /Users/<YOUR_USER>/Library/Developer/Xcode/ and delete "DerivedData" folder.
If in the path of the missing file is the name of a framework e.g. Usabilla.build/Release-iphonesimulator/Usabilla.build/all-product-headers.yaml
Try using an older version, using version 6.4.7 of Usabilla fixed the issue for me.
If the above fixes don't work, here are some info that might help:

At the outset I would like to thank you who ever answers this question.

I do not think this can be done, the only way/workaround is to buy a machine running Macos.
I'm following this tutorial here:
https://www.hackster.io/Salmanfarisvp/googlepi-google-assistant-on-raspberry-pi-9f3677
to use Google Asistant on my Raspberry Pi 3.
I got to step 4 (using the updated SDK) but I get the following output:
INFO:root:Connecting to embeddedassistant.googleapis.com
WARNING:root:Device config not found: [Errno 2] No such file or directory: '/home/pi/.config/googlesamples-assistant/device_config.json'
INFO:root:Registering device
ERROR:root:Option --device-model-id required when registering a device instance
There are some mentions of the same error but the solution presented there doesn't work for me (I already updated the library to the latest version)
Any help would be greatly appreciated.
Thank you !
Please follow this step in the documentation to register a device model.
Then you should include the --device-model-id parameter when you run the sample.
googlesamples-assistant-pushtotalk --project-id my-dev-project --device-model-id my-model

Error: Failed to initialize libusb. LIBUSB_ERROR_OTHER (-99)
I found there is no entry /proc/bus for the attached usb modem.
Can anybody tell me what to do resolve this issue.
I will be very thankful to you.
I am trying to use NS-3.15 on MAC Mountain Lion but when I compile I get the following errors:

If I understand correctly I think this means it can't find those dependencies but I haven't been able to figure out how to add them or where should they even be, could anyone help me out? I am following this tutorial.
I understand this is not a programming question itself but I haven't figured out where to ask so if you know a better place please let me know.
