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)."
