I'm preparing an app for distribution and am trying to get everything right and follow all the guidelines correctly. Here:

https://developer.apple.com/ios/human-interface-guidelines/visual-design/color/#color-management

It says the sRGB color space should be used, and to "...make sure your images include embedded color profiles."

My images were created using sRGB, but according to Finder and Preview they don't have embedded color profiles.

If I open one of the images in Preview and save it again, it then has the color profile:

sRGB IEC61966-2.1

Apple provides an example project for icons and launch images here:

https://developer.apple.com/library/content/samplecode/Icons/Introduction/Intro.html#//apple_ref/doc/uid/DTS40010442

But the images in this project do not have embedded color profiles (at least according to Finder and Preview).

Is this something I need to worry about? Should I re-save all my images with Preview so they have embedded color profiles? Or based on the fact that Apple's example doesn't appear to use embedded color profiles, can I conclude this isn't actually a requirement?

That quote is from the section titled 'Color Management' and doesn't mandate color profiles.

If you're responsible for exact color management of a corporate style guide, as an example, then you can follow those details towards compliance. Otherwise, you are free to ignore.
