UIImageView Extensions
Set of helper methods defined on UIImageView to simplify displaying a user's image.
For most cases, you will likely have one or more
UIImageViews defined for a view controller where you will want to display a user's profile pic and/or cover photo, such as on a profile screen. The methods in this extension simplify that by taking an image id, making a request for that image, and if successful, set an image view's image property to that image.func playPortalImage(forImageId imageId: String?, _ completion: ((_ error: Error?) -> Void)?) -> Void
Request an image by its id and if successful, set as the image view's
image property.Parameter | Type | Description |

error | Error? | The error returned for an unsuccessful request. |
func playPortalProfilePic(forImageId imageId: String?, _ completion: ((_ error: Error?) -> Void)?) -> Void
