  • This switch will determine whether or not duplicate filtering is applied to the Peripheral scanning. If it is applied, then duplicates will be ignored during the discovery process (meaning that the devices are not continuously updated). False/Off means that duplicates ARE being filtered.

    Declaration

weak var ignoreDuplicatesScanningSwitch: UISwitch!

  • This button is the “label” for the switch. I always like my labels to actuate their targets. This toggles the value of the switch.

    Declaration

    Swift

    private class func _parseThisTextForUUIDs(_ inTextToParse: String!) -> [String]

    Parameters
