Hi,
im having an issue with xcode 10 simulators,

since i removed xcode 9 and installed xcode 10, when ever i run a simulator it starts a nsurlsessiond and it downloads until i turn of the internet or close the simulator it dosent mater wich devices im using in the simulator, the process always stars and downlaods.

The worst part is that i use limited data per month and if this continues my data will be finished soon.

So i wanted to know what can i do to stop it?

i tryed other people solution to check the icloud, so i checked and i dont use icloud.

Thank you

While it doesn't look like there will be a general fix that works for everyone from Apple soon, you might be able to solve this by applying a different approach using the System Firewall settings or an external tool that provides similar feature like Lulu. For example running the code to unload the daemon process might lead you to another rabbit hole of Operation not permitted,etc. One approach that solved this for me after sacrificing so much data was to turn on Firewall which is turned off by default and allowing only specific applications to access the internet. Also downloaded the Lulu app and blocked access for the nsurlsessionid daemon from accessing the internet . With this, you can begin to select the applications that get access to your data bandwidth .
