Frequently asked questions
- How long does it take to translate an xcstrings file?
- A typical app with 200 strings can be translated to 10 languages in under 10 minutes. The entire workflow — import, configure, translate, review, export — takes 20-40 minutes compared to 5-20 days with manual translation.
- How much does xcstrings translation cost?
- StringWise Pro costs $79.99/year (U.S. App Store) with a free 3-day trial. Compare this to manual translation which typically costs $600-1,500 per release for a 200-string app translated to 10 languages.
- Is AI translation accurate enough for App Store apps?
- For UI strings, yes. StringWise uses Smart Context to analyze your source code and understand where each string appears (button, alert, settings), which eliminates the ambiguity that makes generic AI translation unreliable.
- What is an xcstrings file?
- An xcstrings file is Apple's String Catalog format introduced in Xcode 15. It stores all localizable strings in a single JSON file, replacing Localizable.strings and .stringsdict. StringWise reads and writes this format directly.
- How many languages does StringWise support?
- StringWise supports 24 languages covering the top App Store markets: English, Spanish, French, German, Italian, Portuguese, Chinese (Simplified/Traditional), Japanese, Korean, Arabic, Russian, and 13 more.
