init(_:unlabeledChildren:displayStyle:ancestorRepresentation:)
Creates a mirror representing the given subject with unlabeled children.
init<Subject, C>(_ subject: Subject, unlabeledChildren: C, displayStyle: Mirror.DisplayStyle? = nil, ancestorRepresentation: Mirror.AncestorRepresentation = .generated) where C : Collection Parameters
- subject
The instance to represent in the new mirror.
- unlabeledChildren
The children to use for the mirror. The collection traversal modeled by
unlabeledChildrenis captured so that the resulting mirror’s children may be upgraded to a bidirectional or random access collection later. See thechildrenproperty for details.- displayStyle
The preferred display style for the mirror when presented in the debugger or in a playground. The default is
nil.- ancestorRepresentation
The means of generating the subject’s ancestor representation.
ancestorRepresentationis ignored ifsubjectis not a class instance. The default is.generated.
You use this initializer from within your type’s customMirror implementation to create a customized mirror, particularly for custom types that are collections. The labels of the resulting mirror’s children collection are all nil.
If subject is a class instance, ancestorRepresentation determines whether ancestor classes will be represented and whether their customMirror implementations will be used. By default, the customMirror implementation of any ancestors is ignored. To prevent bypassing customized ancestors, pass .customized({ super.customMirror }) as the ancestorRepresentation parameter when implementing your type’s customMirror property.
