# numericFormat A string representing a count for the type, e.g. “2 books”. ``` var numericFormat: LocalizedStringResource? ``` ## Discussion In your `numericFormat` implementation, use `StringInterpolation` placeholders and provide a `.stringsdict` file with all possible pluralizations for the type, such as “0 books”, “1 book”, and “2 books”. Example: ``` TypeDisplayRepresentation( name: LocalizedStringResource("Book"), numericFormat: LocalizedStringResource("\(placeholder: .int) books") ) ``` ``` Book NSStringLocalizedFormatKey %#@VARIABLE@ VARIABLE NSStringFormatSpecTypeKey NSStringPluralRuleType one Book other Books %lld books NSStringLocalizedFormatKey %#@count@ count NSStringFormatSpecTypeKey NSStringPluralRuleType NSStringFormatValueTypeKey lld zero %lld books one %lld book other %lld books ``` --- Copyright © 2026 Apple Inc.
