Bolts-Swift | level libraries designed to make developing mobile apps | iOS library

I am attempting to use the MetaWear cocoapod to connect to BLE sensors from my IOS application. Before adding this pod, I created a basic Single View Application in Xcode. I tried to compile and run it on my iPhone, and it showed up as expected.

Having done this, I did a pod init, and updated my Podfile to look as follows, as recommended in the above MetaWear cocoapod link:
