This library doesn't validate the JWT. Any well-formed JWT can be decoded from Base64URL.

Migrating from v2? Check the Migration Guide.


[!IMPORTANT] Check the Support Policy to learn when dropping Xcode, Swift, and platform versions will not be considered a breaking change.

Getting Started


  • iOS 13.0+ / macOS 11.0+ / tvOS 13.0+ / watchOS 7.0+
  • Xcode 14.x / 15.x
  • Swift 5.7+


Swift Package Manager

Open the following menu item in Xcode:

File > Add Packages...

In the Search or Enter Package URL search box enter this URL:


Then, select the dependency rule and press Add Package.


Add the following line to your Podfile:

pod 'JWTDecode', '~> 3.1'

Then, run pod install.


Add the following line to your Cartfile:

github "auth0/JWTDecode.swift" ~> 3.1

Then, run carthage bootstrap --use-xcframeworks.


See all the available features in the API documentation ↗

  1. Import the framework
import JWTDecode
  1. Decode the token
let jwt = try decode(jwt: token)    

JWT parts

Part Property
Header dictionary jwt.header
Claims in JWT body jwt.body
JWT signature jwt.signature

Registered claims

Claim Property
aud Audience jwt.audience
sub Subject jwt.subject
jti JWT ID jwt.identifier
iss Issuer jwt.issuer
nbf Not Before jwt.notBefore
iat Issued At jwt.issuedAt
exp Expiration Time jwt.expiresAt

Custom claims

You can retrieve a custom claim through a subscript and then attempt to convert the value to a specific type.

if let email = jwt["email"].string {
    print("Email is \(email)")

The supported conversions are:

var string: String?
var boolean: Bool?
var integer: Int?
var double: Double?
var date: Date?
var array: [String]?

You can easily add a convenience accessor for a custom claim in an extension.

extension JWT {
    var myClaim: String? {
        return self["my_claim"].string

Error handling

If the JWT is malformed the decode(jwt:) function will throw a JWTDecodeError.

catch let error as JWTDecodeError {

Support Policy

This Policy defines the extent of the support for Xcode, Swift, and platform (iOS, macOS, tvOS, and watchOS) versions in JWTDecode.swift.


The only supported versions of Xcode are those that can be currently used to submit apps to the App Store. Once a Xcode version becomes unsupported, dropping it from JWTDecode.swift will not be considered a breaking change, and will be done in a minor release.


The minimum supported Swift minor version is the one released with the oldest-supported Xcode version. Once a Swift minor becomes unsupported, dropping it from JWTDecode.swift will not be considered a breaking change, and will be done in a minor release.


Once a platform version becomes unsupported, dropping it from JWTDecode.swift will not be considered a breaking change, and will be done in a minor release. For example, iOS 13 will cease to be supported when iOS 17 gets released, and JWTDecode.swift will be able to drop it in a minor release.

In the case of macOS, the yearly named releases are considered a major platform version for the purposes of this Policy, regardless of the actual version numbers.
