Swift – Dollar sign in String

Dollar sign in String in Swift

To include a dollar sign in string in Swift, specify the Unicode value of the dollar sign in the string in Unicode scalar format.

The Unicode scalar value of dollar sign is U+0024. To include this in a string, use the Unicode scalar format as shown in the following code snippet.

let dollarSign = "\u{24}"

Or you can directly specify the dollar sign in the string literal as shown in the following.

let price = "$100.00"

Example

In the following example, we shall create a string literal with dollar sign in it, and print it to standard output.

main.swift

let pricing = "The price is \u{24}100.00."
print(pricing)

Output

Conclusion

In this Swift Tutorial, we learned how to specify dollar sign in a string literal in Swift language, using its Unicode value, with examples.
