I would like to start another discussion about issue with the app crashing.
If you are experiencing a crash, please describe the situation, list the platform you are using, and if possible list the steps to reproduce the crash.
I have tested on iPad (iPad Pro with iOS 11.4) and iPhone (6s, iOS 11.4) and am getting the same problem.
1) Start Polydust app
2) Create new project
3) click “+” to add new image reference
4) select image
5) app crashes. Reproducible on iPad and iPhone with same steps.
