| // InlineDatePicker.swift | ||
| // BeeSwift | ||
| // | ||
| // A date picker component designed to be shown fully inline. Unlike | ||
| // the default inline date picked mode it does not add margin or background. | ||
| // | ||
| // This component modifies private subviews within the UIDatePicker hierarchy, so any | ||
| // changes should be tested against all supported iOS versions | ||
