Build fails on Xcode 9.0.1

[jorge-ramirez]

I am receiving the following warning while trying to build in Xcode 9.0.1 about a redundant protocol conformance, which is causing a segmentation fault in the build process.

/Users/ramij286/Documents/Development/AutoMate-jorge/AutoMate/HealthAlert.swift:15:47: warning: redundant conformance constraint 'Self': 'SystemMessages'
public protocol HealthAlertOk: SystemAlertOk, SystemMessages { }
