When working with an Objective-C project in Xcode 26.5, I'm unable to establish outlet and action connections by dragging between XIB files and the corresponding .h header files. This drag-and-drop connection works perfectly after switching to Xcode 26.3.0. In addition, under Xcode 26.5, drag-and-drop linking works normally for projects using Swift files together with XIB files. The issue only occurs with Objective-C .h files and XIB files.

I'm also having this issue. It's easy to reproduce - just create a new XIB/Objective-C project, add some controls and try to make an outlet with Control-Drag.
Thanks so much for your post and yes this is an issue we have been seeing in the forums.
Please take a look at his post even though is AppKit: https://developer.apple.com/forums/thread/828408
I would recommend as the other posts to I ask you to download the beta 1 version of Xcode 27 and verify if the issue has been resolved or you still having the same issue connecting the IBOutlets?
What the version Xcode that is not working the workaround of dragging from the outlets inspector remains effective?
Please let me know if Xcode 27 resolves the issue for you.
Thanks,
