Code formatter FAQ

How do I format code on this page?

Paste code into the left editor or load a file, choose the options you need, and select Format. Review the result on the right, then copy or save it.

Why might the formatter report an error?

The input must match the selected language or syntax. Check incomplete statements, unmatched brackets or quotes, and a dialect or mode that does not match the input, then format again.

How does a code formatter work?

A code formatter reads language-aware tokens and nested structures, then rewrites indentation, spacing, and line breaks according to a consistent rule set. It does not compile or run the program, so formatting is not a correctness or security check.

Which settings are recommended for this language?

Two spaces and 100 columns are a sensible baseline for new Swift code; Xcode projects also commonly use 4 spaces and 80 columns, so match the repository. Set the indent width and column limit. The result applies consistent spacing and wrapping to valid Swift source.
