Initializer

init(from:_:transform:)

Creates a variant collection from two non-empty symbol variants data using the given transformation closure.

init?<Value1, Value2>(from documentationDataVariants1: DocumentationDataVariants<Value1>, _ documentationDataVariants2: DocumentationDataVariants<Value2>, transform: (DocumentationDataVariantsTrait, Value1, Value2) -> Value)

Discussion

If either symbol data variants values are empty, this initializer returns nil.

This initializer picks a variant (the Swift variant, if available) of the given symbol data as the default value for the variant collection. Other variants are encoded in the variant collection’s variants.
