Thank you, Mark, for your help.
If I summarize, The way to a new class in XCode 4 is the following :
1�)Create the .h and .m files , the same way as before ( from the top
2�)Fish the blue cube "Object" from the Object Library and drag it to
the <Objects> pane of XCode4 IB window
3�)Use the identity inspector to settle the class name. Either by
picking it's name in the drop-down list, which , BTW, is the equivalent
of the "good old" IB <Classes Library> tab, or by beginning to type it's
name in the <class> textField( code completion works there)
Point 3 is essential because I found to my surprise that it is possible
to override the name of "Object", by typing "myNewClass"directly in the
list, and then make connections to other listed class instances !
Of course these phantom connections disappear at building and the App
won't work, but I think users should be warned against that, waiting a
correction of the interface.
