## iOS Installation
### 1 - Setup google-services.plist and dependencies
Setup the `google-services.plist` file and Firebase ios frameworks first; check out the relevant Firebase docs [here](https://firebase.google.com/docs/ios/setup#frameworks).
#### 1.1 - Initialisation
Make sure you've added the following to the top of your `ios/[YOUR APP NAME]]/AppDelegate.m` file:
`#import <Firebase.h>`
and this to the `didFinishLaunchingWithOptions:(NSDictionary *)launchOptions` method:
`[FIRApp configure];`
### 2 - Link RNFirebase
There are multiple ways to install RNFirebase depending on how your project is currently setup:
#### 2.1 - Existing Cocoapods setup, including React Native as a pod
Simply add the following to your `Podfile`:
```ruby
# Required by RNFirebase - you should already have some of these from step 1.
pod 'Firebase/Auth'
pod 'Firebase/Analytics'
pod 'Firebase/AppIndexing'
pod 'Firebase/Core'
pod 'Firebase/Crash'
pod 'Firebase/Database'
pod 'Firebase/DynamicLinks'
pod 'Firebase/Messaging'
pod 'Firebase/RemoteConfig'
pod 'Firebase/Storage'
pod 'RNFirebase', :path => '../node_modules/react-native-firebase'
```
#### 2.2 - Via react-native-cli link
React native ships with a `link` command that can be used to link the projects together, which can help automate the process of linking our package environments.
```bash
react-native link react-native-firebase
```
Update the newly installed pods once the linking is done:
```bash
cd ios && pod update --verbose
```
##### cocoapods
We've automated the process of setting up with cocoapods. This will happen automatically upon linking the package with `react-native-cli`.
**Remember to use the `ios/[YOUR APP NAME].xcworkspace` instead of the `ios/[YOUR APP NAME].xcproj` file from now on**.
#### 2.3 - Manually
If you prefer not to use `react-native link`, we can manually link the package together with the following steps, after `npm install`:
**A.** In XCode, right click on `Libraries` and find the `Add Files to [project name]`.

**B.** Add the `node_modules/react-native-firebase/ios/Firebase.xcodeproj`
![Firebase.xcodeproj in Libraries listing](https://cloud.githubusercontent.com/assets/21329063/24249440/9494e19c-0fd3-11e7-95c0-c2baa85092e8.png)
**C.** Ensure that the `Build Settings` of the `RNFirebase.xcodeproj` project is ticked to _All_ and it's `Header Search Paths` include both of the following paths _and_ are set to _recursive_:
1. `$(SRCROOT)/../../react-native/React`
2. `$(SRCROOT)/../node_modules/react-native/React`
3. `${PROJECT_DIR}/../../../ios/Pods`
![Recursive paths](https://cloud.githubusercontent.com/assets/21329063/24250349/da91284c-0fd6-11e7-8328-6008e462039e.png)
**D.** Setting up cocoapods
Since we're dependent upon cocoapods (or at least the Firebase libraries being available at the root project -- i.e. your application), we have to make them available for RNFirebase to find them.
Using cocoapods is the easiest way to get started with this linking. Add or update a `Podfile` at `ios/Podfile` in your app with the following:
```ruby
# Required by RNFirebase
pod 'Firebase/Auth'
pod 'Firebase/Analytics'
pod 'Firebase/AppIndexing'
pod 'Firebase/Core'
pod 'Firebase/Crash'
pod 'Firebase/Database'
pod 'Firebase/DynamicLinks'
pod 'Firebase/Messaging'
pod 'Firebase/RemoteConfig'
pod 'Firebase/Storage'
```
Then you can run `(cd ios && pod install)` to get the pods opened. If you do use this route, remember to use the `.xcworkspace` file.
