I want to know if anyone used the Google Awareness API on an iOS device. I know it's possible to implement on Android but I need to work on iOS as well, I haven't find any documentation on it so far. Is it possible and how do you implement it?

I had done some researches on google awareness APIs for iOS. It's not available for iOS for now. You can use region monitoring APIs of Apple to register custom fences and monitor if someone enters/exits that region.
You can also notify user locally per region and engage him/her in your app. Apple provides APIs for updating user locally based on location, weather etc.
APIs are simple to use in app.
