# appendLiteral(_:)

Appends a literal segment to the interpolation.

```
mutating func appendLiteral(_ literal: Self.StringLiteralType)
```

## Parameters

`literal`

A string literal containing the characters
that appear next in the string literal.

## Discussion

Don’t call this method directly. Instead, initialize a variable or
constant using a string literal with interpolated expressions.

Interpolated expressions don’t pass through this method; instead, Swift
selects an overload of `appendInterpolation`. For more information, see
the top-level `StringInterpolationProtocol` documentation.
