# Options
This plugin has some options. You can set options in `app.json` like this:

## podVersion (iOS only)
**Default: `latest`**

By default, this plugin sets the `ChannelIOSDK` podspec to:
```ruby
pod 'ChannelIOSDK', podspec: 'https://mobile-static.channel.io/ios/latest/xcframework.podspec'
```

If you need to install a specific package version, you can set the version in `podVersion` option.

```jsonc
{
  "expo": {
    "plugins": [
      ["@peulda/expo-plugin-channel-io", {
        "podVersion": "10.3.0"
      }]
    ]
  }
}
```
It will set the `ChannelIOSDK` podspec to:
```ruby
pod 'ChannelIOSDK', podspec: 'https://mobile-static.channel.io/ios/10.3.0/xcframework.podspec'
```

## `cameraPermission`, `photosPermission` and `microphonePermission` (iOS only)
Channel plugin required [some permissions](https://developers.channel.io/docs/react-native-quickstart#2-add-the-permission-and-description-used-by-sdk). By default, this plugin sets these permissions with following values:

| Key | Value |
| --- | --- |
| `NSCameraUsageDescription` | `Accessing the camera in order to provide a better user experience` |
| `NSPhotoLibraryUsageDescription` | `Accessing to photo library in order to provide a better user experience` |
| `NSMicrophoneUsageDescription` | `Accessing to microphone to record voice for video chat` |

If you already set these permissions via `infoPlist` or other plugins then, This plugin use your values.

```jsonc
{
  "expo": {
    "ios": {
      "infoPlist": {
        "NSCameraUsageDescription": "foo",
        "NSPhotoLibraryUsageDescription": "bar",
        "NSMicrophoneUsageDescription": "baz"
      }
    },
    "plugins": [
      // Permission popup will show with `foo`, `bar`, `baz`
      "@peulda/expo-plugin-channel-io"
    ]
  }
}
```

If you set `cameraPermission`, `photosPermission` and `microphonePermission` options, This plugin override these permissions with plugin values.

```jsonc
{
  "expo": {
    "ios": {
      "infoPlist": {
        "NSCameraUsageDescription": "foo",
        "NSPhotoLibraryUsageDescription": "bar",
        "NSMicrophoneUsageDescription": "baz"
      }
    },
    "plugins": [
      ["@peulda/expo-plugin-channel-io", {
        // Permission popup will show with `camera`, `photos`, `microphone`
        "cameraPermission": "camera",
        "photosPermission": "photos",
        "microphonePermission": "microphone"
      }]
    ]
  }
}
```

If you want disable those permissions, you can set value to `false`.

```json
{
  "expo": {
    "plugins": [
      ["@peulda/expo-plugin-channel-io", {
        "cameraPermission": false,
        "photosPermission": false,
        "microphonePermission": false
      }]
    ]
  }
}
```

# Notice
- Since expo SDK 48, default android minSdkVersion is 21. So [MultiDex is enabled by default](https://developer.android.com/studio/build/multidex#mdex-on-l). For this reason, this plugin does not support android minSdkVersion 20 or lower.
- Since expo SDK 48, default SWIFT_VERSION is 5.0. So, this plugin does not set `SWIFT_VERSION`
- Since expo SDK 48, default iOS minTarget is 13. So, this plugin does not set `Privacy - Photo Library Usage Description`
