to your project.import KingfisherSwiftUI
to your swift file and use the KFImage(myUrl)

QUESTION
I have looked at quite a few examples of using dispatch group but I can't seem to get it to work.
I am using Google Maps for my project, and have placed markers at nearby businesses. When a marker is clicked, I want to show another view controller which has images of the place.

Answered 2018-Sep-06 at 02:57Your use of DispatchGroup currently is all wrong. You should call enter
before an async process starts and you call leave
when the async process is complete. And never call wait
on the main queue. You would want to use notify
. Again though, do not use a dispatch group in this case.
You have two levels of async calls here. The first is in loadImageForMetadata
. That needs to be refactored to provide a completion handler. The second is in loadPhotosForSalonByPlaceId
which also needs to be refactored to provide a completion handler. You also need to redo how you use the dispatch group.
Here is your refactored loadImageForMetadata
