Sticker Pack Issue: Missing App Extension

Everytime I try to run my sticker pack in the xcode simulator I get this:

"The messages stub app com.xyz.abc must have at least one app extension, but none were found."

Anyone know how to fix this?

Make sure that your deployment target is set to the same ios version as the simulator

(got the same issue: my deploment target was set to 10.1 and selected simular to 10.0,

after setting deployment target to 10.0 it works)

Having the same error, @tapblaze

Did you find a solution?

Did anyone find a fix for this?
I have made sure the deployment target is same as iOS version of simulator.

I just fixed this:
Make sure you have added your extension in Embed App Extensions.

Select App extensions from Left column under Products.
Build Phases > Embed App Extensions > Destination=Plugins > Add Extension file
