subscript(explicit:)

Gets the explicit value of the given horizontal alignment guide.

Declaration

subscript(explicit guide: HorizontalAlignment) -> CGFloat? { get }

Overview

Find the horizontal offset of a particular guide in the corresponding view by using that guide as an index to read from the context:

.alignmentGuide(.leading) { context in
    context[.leading] - 10
}

This subscript returns nil if no value exists for the guide.
