<Error>: ImageIO: PNG invalid PNG file: extra chunks between iDOT and IDAT

Just got this funny looking error in my swift project debugger.

There is probably an invalid name of an image somewhere, but I am not sure what

extra chunks between iDOT and IDAT
mean.

Do you have any idea what causes it?

Answer

This issue is completely random and happened to me too with a few images. Probably another Xcode bug.

  1. My image is called "back2@2x.png"
  2. I renamed it to "back2.png"
  3. Ran the project (the image will appear stretched)
  4. Changed it back to "back2@2x.png"
  5. Ran project
  6. FIXED?!

Good-luck hope it helps!
