GrammaticalNumber
Turning singular words to plural can be very hard in some spoken languages, while other languages have simple rules.
GrammaticalNumber is heavily inspired by ActiveSupport::Inflector known from the Ruby on Rails web framework.

GrammaticalNumber will try to match the letter casing of your input word.
Lowercased, uppercased and capitalized words are supported.
"tooth".pluralized() // teeth
"TOOTH".pluralized() // TOOTH
"Tooth".pluralized() // TeethAdd count to words
Prepends the pluralized String with count.
If the count is 0, the singular word will be used.
"child".pluralized(count: 0) // 0 children
"child".pluralized(count: 1) // 1 child
"child".pluralized(count: 3) // 3 children
"knife".pluralized(count: 0) // 0 knives
"knife".pluralized(count: 1) // 1 knife
"knife".pluralized(count: 3) // 3 knives
"sheep".pluralized(count: 0) // 0 sheep
"sheep".pluralized(count: 1) // 1 sheep
"sheep".pluralized(count: 3) // 3 sheepDefine Custom Rules
Uncountable Rule
let rule: GrammaticalNumberRule = .uncountable("money")money will never change.
Irregular Rule: Singular from plural
let rule: GrammaticalNumberRule = .irregular("tooth", "teeth")Turns tooth to teeth when used with pluralized().
Turns teeth to tooth when used with singularized().
Plural Rule: Plural from singular with regular expression
let rule: GrammaticalNumberRule = .plural(#"^(m|l)ouse$"#, #"$1ice"#)mouse becomes mice and louse becomes lice.
Singular Rule: Singular from plural with regular expression
let rule: GrammaticalNumberRule = .singular(#"(matr)ices$"#, #"$1ix"#)Turns matrices to matrix.
Apply rule, so it becomes available
GrammaticalNumberRule.add(rule)Support other languages
In order to support other languages, pass the language parameter to your custom rules.
Call .pluralized(language: yourLanguage) with the same language value — like so: .pluralized(language: "tr")
Example for the turkish language (tr)
GrammaticalNumberRule.add(.plural(#"([aoıu][^aoıueöiü]{0,6})$"#, #"$1lar"#), language: "tr")
GrammaticalNumberRule.add(.plural(#"([eöiü][^aoıueöiü]{0,6})$"#, #"$1ler"#), language: "tr")
GrammaticalNumberRule.add(.singular(#"l[ae]r$"#, #""#), language: "tr")"kitap".pluralized(language: "tr") // kitaplar
"yemek".pluralized(language: "tr") // yemeklerContact
