Local Network Connect - Username field is not lowercased
Username fields are (almost) always entirely lowercase. The current Username UITextField does not have the UITextAutocapitalizationType property set, thus it uses the default value of UITextAutocapitalizationTypeSentences. This causes the first letter typed to be uppercase. I propose setting the UITextAutocapitalizationType property to UITextAutocapitalizationTypeNone for the Username field.
