How to store a user's data to the device?

I am creating a sign in view. I have two UITextField's which are for the user's email and password. When user clicks the 'Sign In' button, these two parameters are sent to my API and check to see if the user exists. If this user exists, my API gets the user's email, name, status and token, and return the JSON result to me. The token had expire date. Hence, I need to store the token and email in the device so the user doesn't have to repeatedly sign in.

I am newbie.So,any code help is appreciated. Thank you.

Update

I have imported LockSmith.swift and LockSmithRequest.swift into my project.And I had also added KeyChainService.swift same as matt blog to project.But I am occurring these problem and my xcode is 6.2.

If you're looking for a very simple drop-in Keychain wrapper, you could take a look at this:

Keychains should be used to store users' emails and passwords. Here are some posts that talk about doing this in Swift:

If you just want to store data within your app, you can use one of the following

  • NSUserDefaults (Suitable for basic small details)
  • CoreData (Suitable for large amounts of dynamically changing data that needs to be queried)
  • Files (Suitable for static content)

In your case, I would suggest using NSUserDefaults.

Assuming you have the information to be stored in the form of NSDictionary. You can follow these steps:

[[NSUserDefaults standardUserDefaults] setObject:[yourDictionary objectForKey:@"token"] forKey:@"token"];
[[NSUserDefaults standardUserDefaults] synchronize];

Later you can retrieve this key like this

[[NSUserDefaults standardUserDefaults] objectForKey:@"token"];

Hope it helps!
