Hello. Some time ago I found, that after every build in appcode I have the same error:

Error:Invalid connection:

All applications are launched very well after build, but i see this error in Messages Build window.

Can anyone tell me how to fix that? Thanks!

Does the same error occur if you build the project in Xcode? If yes (at least, that's the behavior I'm seeing on my side) - it's Apple issue, I'd suggest to file a radar.

Hello, Tatiana. No, Xcode was working good. Want to let you know, that after I updated os x to 10.13, this error disappeared.


Glad to hear it was solved for you. I'm still seeing it on some projects (also running macOS 10.13).
