Key properties include `allowsCellularAccess`, enabling downloads over cellular networks (default: `YES`), and `allowsBackgroundDownloading`, allowing downloads in the background (default: `NO`). You can create instances with custom conditions using `initWithAllowsCellularAccess:allowsBackgroundDownloading:`, or use default settings with `init`. Both methods return a `ModelDownloadConditions` instance.\n"]]
