+                                 THE PROBLEM:
+                                 SwiftUI caches the image when it's shown using the `Image(string)` API.
+                                 Once the image is not showed anymore, SwiftUI doesn't release memory,
+                                 so it keeps caching new images until the app crashes
+                                 UIImage(contentsOfFile: path) doesn't cache the image
+                                 
+                                 THE SOLUTION:
+                                 Using `UIImage(contentsOfFile: path)` images aren't cached.
