Skull icons on heic file after upgrading to iOS 18.0.1

[yeungj16]

Describe the bug

Ever since upgrading to iOS 18.0.1 a few weeks ago. When importing the HEIC files to Darktable, it displays the skull in both lighttable and darkroom.

• MacBook Pro 2023 (Apple M2 Pro) running MacOS 15.0.1
• Darktable v4.8.1
• photos taken on iPhone 16 Pro Max running iOS 18.0.1
• photos taken on iPad Air 5th gen with M1 running iOS 18.0.1

Testing on iPhone 14 Pro Max running iOS 17.6.1 and iPad 9th gen running iOS 18 with no issues.

Steps to reproduce

1. Any Apple device running iOS 18.0.1
2. Ensure the High Efficiency format is used
3. Take some pictures
4. Export pictures using the MacOS Photos app
5. Import pictures into Darktable running v4.8.1
6. Note the skull thumbnails.

Expected behavior

Darktable should be able to open/render the heic files

HEIC files produced by iOS 18 need a more recent libheif version 1.18.2, and I presume the 4.8.1 installer was not using that one...? @zisoft

If you feel adventurous, you could test out the nightly build (you probably want to backup and/or keep your database separate).

[zisoft]

Homebrew is already on 1.18.2, so current master and nightly builds fullfill this requirement. The next release of darktable in december will support this.

4.8.1 most likely does not.

Just wondering how do I check the libheif verion on MacOS. Tried to Google and most are for Linux.

I assumed it's installed as part of Darktable?

Thank you again.

Yes, it is part of the bundle.
It does not help to install libheif separately.
