I’ve saved an image as a 192x192 png file and tried to process it using the ionic resources --icon command in the cli. It provides me with a message Iconic icon resources generator followed by the uploading icon.png… message then I get the command prompt. When I check the ios icons folder there is nothing there. When I process the default ionic icon the same way it generates all the icons into the folder. Any thoughts?
Try the following: Delete any icons and splash screens that are in those folders. I found it does not seem to work sometimes if assets are there.
Then I would also increase my icon to 394 × 394 pixels and double check the dpi (72), then try again.
