# Video Feed Content Source (iOS)

### **Video Feed Content Source**

The enum `VideoFeedContentSource` defines the different sources that can be used to populate the Video Feed/Player Deck/Circle Story.

#### **Channel**

Displays content from the specified channel id.

```swift
let channelID = "<Channel ID>"
let source = VideoFeedContentSource.channel(channelID: channelID)
// UIKit
let videoFeedView = FWSVideoFeedView(source: source)
let playerDeckView = PlayerDeckView(source: source)
let circleStory = CircleStoryView(source: source)
// SwiftUI
FWSVideoFeedSwiftUIView(source: source)
PlayerDeckSwiftUIView(source: source)
CircleStorySwiftUIView(source: source)
```

#### **Channel Playlist**

Displays content from the specified playlist id.

```swift
let channelID = "<Your Channel ID>"
let playlistID = "<Playlist ID>"
let source = VideoFeedContentSource.channelPlaylist(channelID: channelID, playlistID: playlistID)
// UIKit
let videoFeedView = FWSVideoFeedView(source: source)
let playerDeckView = PlayerDeckView(source: source)
let circleStory = CircleStoryView(source: source)
// SwiftUI
FWSVideoFeedSwiftUIView(source: source)
PlayerDeckSwiftUIView(source: source)
CircleStorySwiftUIView(source: source)
```

#### **Dynamic Content**

Displays dynamic content based on the provided channel id and content parameters.

```swift
let channelID = "<Channel ID>"
let parameters: DynamicContentParameters = ["<cohort key>": ["<cohort value 1>", "<cohort value 2>"]]
let source = VideoFeedContentSource.dynamicContent(channelID: channelID, parameters: parameters)
// UIKit
let videoFeedView = FWSVideoFeedView(source: source)
let playerDeckView = PlayerDeckView(source: source)
let circleStory = CircleStoryView(source: source)
// SwiftUI
FWSVideoFeedSwiftUIView(source: source)
PlayerDeckSwiftUIView(source: source)
CircleStorySwiftUIView(source: source)
```

#### Hashtag Playlist

Displays content based on the provided channel id and the hashtag expression.

```swift
let channelID = "<Channel ID>"
let singleHashtag = "dogs"
let source = VideoFeedContentSource.hashtagPlaylist(channelID: channelID, filterExpression: singleHashtag)
// UIKit
let videoFeedView = FWSVideoFeedView(source: source)
let playerDeckView = PlayerDeckView(source: source)
let circleStory = CircleStoryView(source: source)
// SwiftUI
FWSVideoFeedSwiftUIView(source: source)
PlayerDeckSwiftUIView(source: source)
CircleStorySwiftUIView(source: source)
```

Or a more advanced hashtag expression can be used to fine tune the results

```swift
let channelID = "<Channel ID>"
let filterExpression = "(and sport (or food comedy))"
let source = VideoFeedContentSource.hashtagPlaylist(channelID: channelID, filterExpression: filterExpression)
// UIKit
let videoFeedView = FWSVideoFeedView(source: source)
let playerDeckView = PlayerDeckView(source: source)
let circleStory = CircleStoryView(source: source)
// SwiftUI
FWSVideoFeedSwiftUIView(source: source)
PlayerDeckSwiftUIView(source: source)
CircleStorySwiftUIView(source: source)
```

#### SKU Playlist

Displays content based on the provided channel id and SKU/Product external IDs.

```swift
let channelID = "<Encoded Channel ID>"
let productIDs = ["<Product ID>", ...]
let source = VideoFeedContentSource.skuPlaylist(channelID: channelID, productIDs: productIDs)
// UIKit
let videoFeedView = FWSVideoFeedView(source: source)
let playerDeckView = PlayerDeckView(source: source)
let circleStory = CircleStoryView(source: source)
// SwiftUI
FWSVideoFeedSwiftUIView(source: source)
PlayerDeckSwiftUIView(source: source)
CircleStorySwiftUIView(source: source)
```

#### Single Video or Live Stream

Displays a single video or live stream content.

```swift
let videoID = "<Video ID>"
let source = VideoFeedContentSource.singleContent(contentID: videoID)
// UIKit
let videoFeedView = FWSVideoFeedView(source: source)
let playerDeckView = PlayerDeckView(source: source)
let circleStory = CircleStoryView(source: source)
// SwiftUI
FWSVideoFeedSwiftUIView(source: source)
PlayerDeckSwiftUIView(source: source)
CircleStorySwiftUIView(source: source)
```

#### Video Ads

Displays video ads based on vast XML.

```swift
// Specifies which channel the video ads should be created under.
let adChannelId = "<Channel ID>"
// The vast XML.
let vastXml = "<Vast XML>"
let source = VideoFeedContentSource.videoAds(adChannelId: adChannelId, vastXml: vastXml)
// UIKit
let videoFeedView = FWSVideoFeedView(source: source)
let playerDeckView = PlayerDeckView(source: source)
let circleStory = CircleStoryView(source: source)
// SwiftUI
FWSVideoFeedSwiftUIView(source: source)
PlayerDeckSwiftUIView(source: source)
CircleStorySwiftUIView(source: source)
```

#### Channel Videos

```swift
let channelID = "Encoded channel id"
let videoIDs = ["Encoded video id 1", "Encoded video id 2", ...]
let source = VideoFeedContentSource.channelVideos(channelID: channelID, videoIDs: videoIDs)
// UIKit
let videoFeedView = FWSVideoFeedView(source: source)
let playerDeckView = PlayerDeckView(source: source)
let circleStory = CircleStoryView(source: source)
// SwiftUI
FWSVideoFeedSwiftUIView(source: source)
PlayerDeckSwiftUIView(source: source)
CircleStorySwiftUIView(source: source)
```
