Image Catalog in DevelopmentPods

CocoaPods supports using xcassets in your pod library. Add resource_bundle to your podspec:

s.resource_bundle = { 'Media' => 'Sources/Media.xcassets'}

And here is your diretory looks like:

│── Sources
│   ├── Info.plist
│   ├── Media.xcassets
│   │   ├── ChatRoom_Bubble_Text_Receiver_White_57x40_.imageset
│   │   │   ├── ChatRoom_Bubble_Text_Receiver_White_57x40_@2x.png
│   │   │   ├── ChatRoom_Bubble_Text_Receiver_White_57x40_@3x.png
│   │   │   └── Contents.json
│   │   └── ChatRoom_Bubble_Text_Sender_Green_57x40_.imageset
│   │       ├── ChatRoom_Bubble_Text_Sender_Green_57x40_@2x.png
│   │       ├── ChatRoom_Bubble_Text_Sender_Green_57x40_@3x.png
│   │       └── Contents.json

Create a helper function to simplify loading images:

class Utility {
    
    static var bundle: Bundle? = {
        if let url = Bundle(for: WXUtility.self).url(forResource: "Media", withExtension: "bundle") {
            return Bundle(url: url)
        }
        return nil
    }()
    
    static func image(named: String) -> UIImage? {
        return UIImage(named: named, in: bundle, compatibleWith: nil)
    }
}

Now you can load your image using following code:

let image = Utility.image(named: "my_img")
