Belgilar

Swift belgilar (Character)

Character — foydalanuvchiga ko‘rinadigan bitta belgi.

Stringlar belgilar kolleksiyasidir.

Belgilar va string uzunligi

Yakka harflar uchun Character dan foydalaning.

Belgilar sonini olish uchun String.count dan foydalaning.

let ch: Character = "A"
print(ch)
let word = "Swift"
print(word.count)

Bu misol belgini va string uzunligini chiqaradi.

Belgilar va stringlarni o‘zaro o‘zgartirish

Kerak bo‘lganda Character va String tiplarini bir-biriga o‘zgartiring.

let ch: Character = "A"
let s = String(ch)
print(s)              // "A"

Unicode va grafema klasterlari

Ba’zi belgilar bir nechta Unicode skalyaridan iborat bo‘lsa ham, bitta belgi sifatida hisoblanadi.

let heart: Character = "❤️"
print(heart)
let flag: Character = "🇳🇴" // composed of two regional indicators
print(flag)
print("e\u{301}".count) // 1 (e + combining acute accent)
