I just recently purchased this book (5th ed) but cannot complete even the first project with xcode 8.3. Xcode 8.3 no longer gives you the option to not use a storyboard when creating a mac os application. I can create the xib file for the password generator app and add the button and label. I figured out how to remove the storyboard as the main entry point in the general preferences so my window will display, however i get the error : “Failed to connect (window) outlet from (NSApplication) to (NSWindow): missing setter or instance variable” . I get a similar error for my text field and my button. Please help!
