# iOS/Swift helper functions for storing data in Keychain

This is a collection of helper functions for writing/reading text from a Keychain.

As you probably noticed Apple's keychain API is a bit verbose.
This class was designed to provide shorter syntax for accomplishing a simple task: reading/writing text values for specified keys.

## Installation

Copy [TegKeychain.swift](https://raw.githubusercontent.com/exchangegroup/keychain-swift/master/keychain/TegKeychain.swift) into your project.

## Usage

```Swift
TegKeychain.set("my key", value: "hello world")

TegKeychain.getString("key 1")

TegKeychain.delete("my key")

TegKeychain.clear()
```

In addition to strings one can set/get `NSData` objects.

```Swift
TegKeychain.set("my key", value: nsDataObject)

TegKeychain.getData("my key")
```
