Issues after updating to IOS11 and Xcode9!! "com.google.Maps.LabelingBehavior", "TIC Read Status"

Question

I have updated my phone and Xcode to the most recent update and I am getting tons of warnings.

First one is 2017-09-21 00:23:15.669466+0100 The Kallos[12068:1279021] TIC Read Status [1:0x0]: 1:57

and there is literally 2-3 posts about this which doesn't even explain what it is!

This is another warning, I found a similar post which explains this issue but it doesn't give a solution on how to fix it!

Next warning is

I feel like this is a problem with the GoogleMaps API and not my code but Im not sure about that.

I will be more than happy to provide more information if needed but my project has around 11-12k lines of codes so I don't really know what to upload.
