Hi, Did you figure out to fix this issue. We are facing the same issue.

The Crash was happening in 10.14 and 10.15 devices as well.

The above mentioned devices are macOS

When the app was build through Xcode 16RC the app was crashed in the devices macOS version having macOS 10.13, 10.14, 10.15. If the app was build through Xcode 15 the app was working fine in all the devices. The crash report says QuicklookUI framework not found. As a part of testing, I commented all the code which uses QuicklookUI API's and the App was running fine in all the devices. Now, the issue is why the App was building fine in Xcode 15 and not in Xcode 16. Please find the below crash report. Crash Report

@DTS Engineer Any update on this? In Recent macOS 15.1 Beta 5 Release date, It was mentioned that it was a known issue. Was this going to be fixed or we have to look any alternatives? Please provide the information
