Photoshop does not support HEIC images that are created using the new iOS?? I'm sure Apple didn't keep it a secret. Sounds like another pissing match between Adobe and Apple. Grow up and act like adults and support HEIC.
HEIC is the file format name Apple has chosen for the new HEIF standard – and actually, with the new CC 2018 release that came out last month, "Photoshop now supports Apple's High Efficiency Image Format (HEIF)."
MANY teams count on Adobe products being cross-platform for Apple and Windows! HEIC SHOULD open in any latest version of PhotoShop. I have Creative Cloud and updated my PhotoShop this morning when I came across a HEIC photo file sent in from a team member in the field. Very disappointed to see the error message, "Camera Raw does not support HEIC on Windows." Boo!
