Since the XCode the 12.2 upgrade (and Big Sur upgrade), my projects have been plagued with the "No Assistant Results" issue, and nothing I've tried has resolved it.

This morning I broke down and started to reproduce a small project from scratch, and as I was dragging a control into into the ViewController code, the code vanished and was replaced by the "No Assistant Results" message.

Is this a known issue? Does anybody have any sure-fire fixes that aren't found in the first page of a google search?

I've only been using XCode for a few weeks, so be gentle.
Thanks

 I was dragging a control into into the ViewController code

What did you do exactly ? What type of control ? A button ?

  • If you drag a control you drag it in the canvas of Interface Builder, not in ViewController code.

  • Then you may control-drag from this control to the code to create the IBOutlet.

  • Note that you must have declare the ViewController in Interface Builder to be of the class of the ViewController class defined in code that you want to connect to.


So, please explain in detail what you did and when exactly the problem occurred.
