iOS Indoor Location project

I am new to Swift and iBeacons, but would like to track the position of multiple iPhones on a specific location.

I have started with completing the tutorial on the Estimote website :

But having troubles outputting values.
This is what I get in console:

2017-11-16 18:12:39.126676+0000 HelloIndoorAKT[1362:312135] [DYMTLInitPlatform] platform initialization successful
2017-11-16 18:12:39.485443+0000 HelloIndoorAKT[1362:311987] [Accessibility] ****************** Loading GAX Client Bundle ****************
2017-11-16 18:12:40.155484+0000 HelloIndoorAKT[1362:311987] refreshPreferences: HangTracerEnabled: 0
2017-11-16 18:12:40.155635+0000 HelloIndoorAKT[1362:311987] refreshPreferences: HangTracerDuration: 500
2017-11-16 18:12:40.156148+0000 HelloIndoorAKT[1362:311987] refreshPreferences: ActivationLoggingEnabled: 0 ActivationLoggingTaskedOffByDA:0

My main goal is to understand how to retrieve the position x and y values and then later how to scale this to multiple users.

Hope someone can help
