First, add the following line to your Podfile

pod install 'GenericLocalPersistence', '~> 0.0.1’

pod 'GenericLocalPersistence', :git => ''

Usage of UserDefault

import GenericLocalPersistence

Set & Get value from User Default

DefaultManager().saveValueInDefault(value: "TestValue", using: "TestKey")
let valueFetch:String = DefaultManager().getValue("TestKey") ?? ""

Usage of Plist

import GenericLocalPersistence

Set & Get value from plist file

Replace "userDetails" with custom name for creating plist file to store data

private let managerPlist = plistManager(named: "userDetails")
managerPlist?.saveDatatoPlist(value: "TestString Value", using: "TestKey")
let stringValue :String = managerPlist?.getDictionary(key: "TestKey") ?? ""

Usage of KeyChain

import GenericLocalPersistence

Set & Get value from KeyChain file

Store password value

let passWordString = textPassword?.text?.data(using: .utf8, allowLossyConversion: false) ?? Data()
let passwordStatus = KeyChainManager()?.save(key: "com.appBundleID.password", data: passWordString)

//Retrive data

if let receivedData = KeyChainManager()?.load(key: "com.appBundleID.password") {
    let data = String(decoding: receivedData, as: UTF8.self)
    print("result: ", data)

Store username value

let userNameString = textName?.text?.data(using: .utf8, allowLossyConversion: false) ?? Data()
let emailStatus = KeyChainManager()?.save(key: "", data: userNameString)

//Retrive data

if let data = KeyChainManager()?.load(key: "") {
    let data = String(decoding: data, as: UTF8.self)
    print("result: ", data)


Replace "com.appBundleID" with your project bundleID for KeyChain integration
Define the dataType in which you want to fetch the value and that’s the way you can get the stored value.
