| 57 THE PROBLEM: | |
| 58 SwiftUI caches the image when it's shown using the `Image(string)` API. | |
| 59 Once the image is not showed anymore, SwiftUI doesn't release memory, | |
| 60 so it keeps caching new images until the app crashes | |
| 61 UIImage(contentsOfFile: path) doesn't cache the image | |
| 62 | |
| 63 THE SOLUTION: | |
| 64 Using `UIImage(contentsOfFile: path)` images aren't cached. | |
