Xcode 7 warning: The launch image does not have a valid extension

Asked 17/9, 2015 at 14:14 Answered 16/2, 2017 at 16:24

Xcode 7 has warnings for my launch image set. It reads:

The launch image set "LaunchImage" references a file "[email protected]", but that file does not have a valid extension.

I tried removing the image and put it back again with no luck. What is it warning about and how can I fix it?

It wasn't used to be a problem in previous Xcode versions! But Xcode 7 seems to care about names. Thanks! – Sinistrocular 17/9, 2015 at 14:38

it has worked, I was experiencing same error – Analogize 15/9, 2021 at 6:19

Can't comment, yet found this helpful:

After renaming the image's extension name to lowercase the warning goes away (as explained in the accepted answer: .PNG -> .png)

If the warning doesn't go away, clean the project by going to Product -> Clean

(or just: Shift + CMD + K)

If you have the file Image.PNG, convert it into Image.png, and if you have the file extension Image.JPG, convert it into Image.jpg.

Make sure your images have extension with lowercase letters, not capital letters. Hope this will help!
