28 THE PROBLEM:
425078c01194 refactor code
Dennis C. M. <dennis@denniscm.com>
parents: 23
diff changeset
29 SwiftUI caches the image when it's shown using the `Image(string)` API.
425078c01194 refactor code
Dennis C. M. <dennis@denniscm.com>
parents: 23
diff changeset
30 Once the image is not showed anymore, SwiftUI doesn't release memory,
425078c01194 refactor code
Dennis C. M. <dennis@denniscm.com>
parents: 23

31 so it keeps caching new images until the app crashes

32 UIImage(contentsOfFile: path) doesn't cache the image

34 THE SOLUTION:

35 Using `UIImage(contentsOfFile: path)` images aren't cached.
