Jpeg images in Xcode project reported to to be invalid

Question

After upgrading (Swift and Xcode - some time ago already), I now have a warning for every .JPG image in my project (I have 200+ JPG images in the project):

The image set "Image1" references a file "Image1.JPG", but that file does not have a valid extension.

How do I get rid of the warnings/fix the root cause of the issue?

Answer 1

It looks like .JPG is not a valid file extension for Xcode 7. Try changing all .JPG to .jpg and the problem should be gone.

Same rule applies to images with .PNG extensions too.

Answer 2

To clarify, it's true that you need to use a lowercase .jpg extension, but you don't have to import all of the images again. You can just rename the image files in the imageset folder to have a lowercase extension and edit the contents.json file associated with it to reference the lowercase .jpg extension.
