assets.xcassets Folder is just raw code

Hey everyone, I took over a mac os app project file and the Assets folder is looking strange. It doesn't have the regular interface where you see the list of assets and the section of adding the app icon size variants and so on. It's just a document of raw data referencing the assets. It's not recognizing the folder as a normal assets folder. Any idea how I can fix it?
