Supporting Reachability.swift

Keeping Simple-KeychainSwift up-to-date is a time consuming task. Making updates, reviewing pull requests, responding to issues and answering emails all take time. If you'd like to help keep me motivated, please download my free app, Photo Flipper from the App Store. (To really motivate me, pay $1.99 for the IAP 😀)

And don't forget to ★ the repo. This increases its visibility and encourages others to contribute.

Thanks Ash


To run the example project, clone the repo, and run pod install from the Example directory first.



Just drop the Keychain.swift file into your project. That's it!

Swift Package Manager

Simple-KeychainSwift is available through Swift Package Manager. Xcode 11.0+ is required. To install, open Xcode -> File -> Swift Packages -> Add Package Dependency and paste repo's address

Simple-KeychainSwift is available under the MIT license. See the LICENSE file for more info.

Example usage

Simple-KeychainSwift declares a protocol TypeSafeKeychainValue:

public protocol TypeSafeKeychainValue {
    func data() -> Data?                   // Convert to Data
    static func value(data: Data) -> Self? // Convert from Data

You can use Simple-KeychainSwift to set any types that conform to this protocol. Currently supported are String, Int, Bool and Date, To set other types, add conformity to TypeSafeKeychainValue, e.g.

extension Int: TypeSafeKeychainValue {
    public func data() -> Data? {
        var value = self
        return Data(bytes: &value, count: MemoryLayout.size(ofValue: value))
    public static func value(data: Data) -> Int? {
        return data.withUnsafeBytes { $0.pointee }

Set a key/value pair

Keychain.set("some value", forKey: "some string")
Keychain.set(true, forKey: "some bool")
Keychain.set(Date(), forKey: "some date")
Keychain.set(27, forKey: "some int")

Retrieve the value for a key

Keychain.value(forKey: "some string") as String
Keychain.value(forKey: "some bool") as Bool
Keychain.value(forKey: "some date") as Date
Keychain.value(forKey: "some int") as Int

Delete a key/value pair

Keychain.removeValue(forKey: "my key")

Delete all values from the keychain
