Assets.car can't contain 16-bit or P3 assets if the app supports iOS 8 or earlier?

Question

Has anyone come across this error when uploading to iTunesConnect. Upload precess gets to \"Verifying assets with iTunes store\" the I get the following error:

Answer 1

I've found the offending images with the @fancy steps but I couldn't change the color profile of my images with the above solutions.

I've tried with ColorSync, Preview, and I was unable to change the color profile of the offending images.

Finally I could change the color profile using convert command.

convert my_image.png -profile /path/to/AdobeRGB1998.icc -profile /path/to/sRGB_v4_ICC_preference_displayclass.icc my_image.png

After this, the appropiated color profile (sRGB...) was shown on Finder > File > Get Info and finally I was able to upload my app using Application Loader.

If you want to try this method:

1) Download ImageMagick using brew:

brew update
brew install imagemagick --with-little-cms --with-little-cms2

2) Download the color profiles:

• AdobeRGB1998 > https://www.adobe.com/digitalimag/adobergb.html
• sRGB_v4_ICC_preference_displayclass.icc > http://www.color.org/srgbprofiles.xalter

3) Execute the following command:

convert input_image_name.ext -profile /path/to/AdobeRGB1998.icc -profile /path/to/sRGB_v4_ICC_preference_displayclass.icc output_image_name.ext

Answer 2

Was able to resolved using the ff steps:

1. Double checked all my Assets and made sure there's no P3 by using @fancy answer.
2. Manually look into Xcode Assets for non-RGB color space.
3. Set deployment target from 8.3 to 8.2

Answer 3

If you need to resolve the issue on temporary basis just increase its minimum development target to iOS 9.0 and this issue will be resolved.

Answer 4

Inspired by Ignacio, I have been able to convert all the AdobeRGB1998 images to sRGB images with the following scripts

Install imagemagick

brew update
brew install imagemagick --with-little-cms --with-little-cms2

Find images and convert them to sRGB profile

cd path>to>Images.xcassets>folder
find . -name '*.png' -exec convert "{}" \
-profile    "/System/Library/ColorSync/Profiles/AdobeRGB1998.icc" \
-profile "/System/Library/ColorSync/Profiles/sRGB Profile.icc" \
"{}"  \;

If you don't have AdobeRGB1988.icc on you mac

Consider downloading it here AdobeRGB1998 https://www.adobe.com/support/downloads/iccprofiles/iccprofiles_mac.html https://www.adobe.com/digitalimag/adobergb.html

Answer 5

1. Find in your assets catalog icons with attribute Adobe RGB (1998).
2. Replace it with icon with attribute sRGB IEC61966-2.1

because, it needs to be changed to 8bit sRGB
