syllabreak-swift

Multilingual library for accurate and deterministic hyphenation and syllable counting without relying on dictionaries.

This is a Swift port of syllabreak Python library.

Supported Languages

• 🇬🇧 English (eng)
• 🇷🇺 Russian (rus)
• 🇷🇸 Serbian Cyrillic (srp-cyrl)
• 🇷🇸 Serbian Latin (srp-latn)
• 🇹🇷 Turkish (tur)
• 🇬🇪 Georgian (kat)
• 🇩🇪 German (deu)

Usage

Auto-detect language

When no language is specified, the library automatically detects the most likely language:

import Syllabreak

let s = Syllabreak(softHyphen: "-")
print(s.syllabify("hello"))
// hel-lo
print(s.syllabify("здраво"))  // Serbian Cyrillic
// здра-во
print(s.syllabify("привет"))  // Russian
// при-вет

Specify language explicitly

You can specify the language code for more predictable results:

let s = Syllabreak(softHyphen: "-")
print(s.syllabify("problem", lang: "eng"))  // Force English rules
// pro-blem
print(s.syllabify("problem", lang: "srp-latn"))  // Force Serbian Latin rules
// prob-lem

This is useful when:

• The text could match multiple languages
• You want consistent rules for a specific language
• Processing text in a known language

Language Detection

The library returns all matching languages sorted by confidence:

import Syllabreak

let s = Syllabreak()
print(s.detectLanguage("hello"))
// ["eng", "srp-latn", "tur"]  // Matches English, Serbian Latin and Turkish
print(s.detectLanguage("čovek"))
// ["srp-latn", "eng", "tur"]  // Serbian Latin has highest confidence due to č
