Check in the interface builder if the property selection is set to 'No selection'. Change it to 'Single selection' or other option according to your needs. This might be the reason why didSelect is not getting triggered. I hope it helps.

The proper way to solve this problem would be repacking the embedded framework with XCFramewotk but there is a work around to solve this in the meantime. Go to Build Settings Build Options and change the property value of Validate Workspace to YES. You should be all set. Refer to xcodebuildsettings.com to understand more about this configuration.

This is happening with me as well. Any updates from @apple team?
