It seems all is well after adding QTPLUGIN += qsqlite to the ios section of my Qt project file.

I've attached the app's crash report: ELD-2024-05-08-130942.ips.crash

NetworkExtension.framework was present on the General tab under the section "Frameworks, Libraries, and Embedded Content. However, it was listed with Do Not Embed. Changing it to Embed & Sign caused a new error: Command CodeSign failed with a nonzero exit code I then changed all of the frameworks to the Embed Without Signing. This allowed the build to complete, but the install to the iPhone failed. The details on the failure error included the phrase Could not inspect the application package.. Deleting the app on the iPhone and trying again gave the same error. An internet search suggested doing a "clean". I changed the framework option back to Do Not Embed and did a clean. Things worked after doing a rebuild. I did do a clean prior to this yesterday, so I'm not sure which steps were required to get things back on the rails. However, things are back to working now. Many thanks Quinn!
