Xcode Instruments "Networking recording service not found"

Question

I want to use Xcode instruments to analyze network traffic of my iOS app. Unfortunately instruments seems to be broken.

I already reinstalled Xcode (incl. Instruments).

Any suggestions on how to fix this?

Used Versions:

• Xcode 9.4.1 (9F2000)
• Instruments 9.4.1 (9F2000)

Answer 1

Looks like the Network Connections instrument is installed when you install the Xcode 10 beta. I just verified that on my machine which has the beta installed Network Connection shows up while on another machine that has 9.4.1 but not the Xcode 10 beta it does not show up.

You might want to file a radar about this so Apple can look in to it...

Answer 2

Unfortunately, custom instruments not working with the simulator are a known issue.

There are few that works now, such as Leaks.

You always have the option to plug a real device, this will work.
