Hey,
I‘m building a proven document-based app with Xcode 15 / macOS 14 SDK with a deployment target of macOS 10.13. After some adjustment due to unclipped views and state restoration, everything works fine under Sonoma.
But on older systems (e.g. macOS 10.14) invoking an NSSavePanel directly throws an exception:
1: "*** -[NSPathStore2 stringByAppendingPathExtension:]: nil argument
I‘m not explicitly fiddling with the path extension, and the code works - as mentioned - under some (old and new) macOS versions. The macOS 15 AppKit release notes are listing some changes to NSSavePanel, maybe the issue is related…
Has anyone made similar observations - and knows a potential fix?
Greetings, Mattes
