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.
