SwiftToml is a TOML parser written in the swift language. TOML is an intuitive configuration file format that is designed to be easy for humans to read and computers to parse.

SwiftToml currently parses files that conform to version 0.4.0 of the TOML spec.

For full details of writing TOML files see the TOML documentation.


TOML files are parsed using one of two functions:

  1. Read TOML from file
  2. Parse TOML from string

Both functions return a Toml object of parsed key/value pairs

Parse TOML from file on disk

import Toml
let toml = try Toml(contentsOfFile: "/path/to/file.toml")

Parse TOML from string

import Toml
let toml = try Toml(withString: "answer = 42")

Get raw values from TOML document

import Toml
let toml = try Toml(contentsOfFile: "/path/to/file.toml")

// string value
print(toml.string("table1", "name"))

// boolean value
print(toml.bool("table1", "manager"))

// integer value
print("table1", "age"))

// double value
print(toml.double("table1", "rating"))

// date value
print("table1", "birthday"))

// get value and resolve type at runtime
print(try toml.value("title")!)

// get array of type [String]
let array: [String] = toml.array("locations")!

// get table
let table1 = toml.table("table1")

// iterate over all tables at the root level
for (tablePath, table) in toml.tables() { ... }

// iterate over all tables under table1
for (tablePath, table) in toml.tables("table1") { ... }


Add the project to to your Package.swift file as a dependency:

dependencies: [
    .Package(url: "", majorVersion: 1)


SwiftToml is compatible with Swift 4.0.3 and TOML 0.4.0.

It has been tested with Swift 4.0.3 on Mac OS X and Ubuntu 16.04.
