combineExplicit(_:)
Merges a sequence of explicit alignment values produced by this instance.
Declaration
func combineExplicit<S>(_ values: S) -> CGFloat? where S : Sequence, S.Element == CGFloat?Discussion
For most alignment types, this method returns the mean of all non-nil values. However, some types use other rules. For example, firstTextBaseline returns the minimum value, while lastTextBaseline returns the maximum value.
