I'm working on a functionality on my code - where it will add a flag to the map once an image is added to the app (via the second page, not shown) but it just doesn't perform how I want. Basically the photo saving is working perfectly and shows via the terminal where and how something is saving and the flags or pins that are added to the map also do save however just to see the you have to go to the second page (press on it) and come back to page 1 (Map) to see them - I just want to be able to see them from the start of the app. I tried init() { loadSavedImages(for: "") loadSavedImageLocations()
but this doesn't really help much - if anyone can help it would really be apperciated.
