I have the same issue, but there is something you can do to,
1) Go in Product -> Scheme -> Edit Scheme
2) Run Section on the left, select Argument Tab and in Environment Variable put this.
OS_ACTIVITY_MODE to value : disable.
For more information please find the below screenshot.
This will get rid of messages in the console.
But I still struggle with the PLBuildVersion is implemented in both….
I hope this helps you !
*** EDIT ****
I found that the issue was caused by Facebook SDK. I removed the framework from CocoaPods, installed it manually by copying the SDK in my project folder and I have no errors now.
