Finder Sync + XPC Launch Agent

Hi

I have a problem with communication between Finder Sync and XPC service as Launch Agent. When I try execute some function, invalidation handler was called and get error "Error Domain=NSCocoaErrorDomain Code=4099 "Couldn’t communicate with a helper application." (The connection to service named com.com4it.test was invalidated.) UserInfo=0x60800026af80 {NSDebugDescription=The connection to service named com.com4it.test was invalidated.}"

All application are signed and add to the same App Group.


XPC Service is working because I can connect from another app and it works.


Pleas help me

I’m going to recommend that you open a DTS tech support incident so I can look into your issue in depth.

It looks like I'm getting a similar issue to you: https://forums.developer.apple.com/message/134201#134201


Did you get this solved?

It looks like I'm getting a similar issue to you …

To clarify, the COM4IT’s problem was that they have three chunks of code:

  • the host app (A)

  • a Finder Sync extension (B)

  • an XPC service (C)

and they want both A and B to be able to talk to C via NSXPCConnection (or the C API API). It wasn’t clear from the post you referenced whether you have C. It looks like that the 

NSXPCConnectionInvalid
(4099) error in your log is coming from the XPC-based system infrastructure that runs the communication channel to your share extension, which makes it a very different problem.

I’m sorry but I'm not able to provide one-on-one help via email. You have a couple of choices:

  • You can open a new thread here on DevForums describing your specific problem, and I’ll try to help out there. That way everyone will be able to benefit from my response.

  • If you want one-on-one support, you should open a DTS tech support incident and I can help you out in that context.
