## Getting started

###  Installation (xcode)

1. `npm install react-native-apple-healthkit@https://github.com/GregWilson/react-native-apple-healthkit.git --save`
2. In XCode, in the project navigator, right click `Libraries` ➜ `Add Files to [your project's name]`
3. Go to `node_modules` ➜ `react-native-apple-healthkit` and add `RCTAppleHealthKit.xcodeproj`
4. In XCode, in the project navigator, select your project. Add `libRCTAppleHealthKit.a` to your project's `Build Phases` ➜ `Link Binary With Libraries`
5. Click `RCTAppleHealthKit.xcodeproj` in the project navigator and go the `Build Settings` tab. Make sure 'All' is toggled on (instead of 'Basic'). In the `Search Paths` section, look for `Header Search Paths` and make sure it contains both `$(SRCROOT)/../../react-native/React` and `$(SRCROOT)/../../../React` - mark both as `recursive`.
5. Compile and have fun

### Usage

Just `require` the `react-native-apple-healthkit` module and you're ready to go!
```javascript
var AppleHealthKit = require('react-native-apple-healthkit');

...

let healthKitOptions = {
    permissions: {
        read: ["Height", "Weight", "Steps", "DateOfBirth", "BodyMassIndex"],
        write: ["Weight", "Steps"]
    }
};

AppleHealthKit.initHealthKit(healthKitOptions, (err, res) => {
    if(err) {
        console.log("error initializing healthkit: ", err);
        return;
    }
    console.log("HEALTHKIT INITIALIZED!");
    // ...
});

...
