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

Finally i find a temporary solution!


rename the file com.apple.nsurlsessiond(Dont delete) in

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/UserEventPlugins/com.apple.nsurlsessiond.plugin/

to something -com.apple.nsurlsessiond


and also the file nsurlsessiond(Dont delete) in

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/libexec/

to something -nsurlsessiond

Please do not suggest this temporory solution!
If you rename file, xCode will not able open simulator.

An alternative to @vinukn335 temporary solution should be to use a host-based application firewall like Little Snitch to deny the internet access of nsurlsessiond

Te solution proposed by @vinukn335 worked for me. After applying it Xcode was able to open the simulator without problems and the downlading dissapeared.

As I mentioned above the best solution for this problem in the mean time is to use a host-based application firewall like Little Snitch or Lulu to deny the internet access of nsurlsessiond. You just need to create a rule to deny internet access for:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/libexec/nsurlsessiond

Check this screenshot to get an idea:

I also had the same problem.

The solution...

Just go to settings > software update > Advanced (lower right corner) > turn off "Download when available"

Thats it.

Your problem solved.

You are most welcome. (-:
