I’ve just started the IOS Apprentice tutorials, both the online videos and the book. The Xcode Editor preview panel does not work as presented in either the video or the book.
My equipment: iMac 2019 3.6GHz Quad-Core i3 processor, 16 GB Ram, Catalina 10.15.4
Xcode version: 11.4.1
I’m only at the very beginning tutorial with the Hit Me button and Pop Up alert when the button is pushed. The Preview is set to iPhone XE (2nd gen), but this doesn’t seem to affect the performance. The Preview is very slow. It can take 1 - 2 minutes for the Preview to refresh. I had to turn off automatic refresh. It will not allow me to add the 2nd button on the Preview pane. I press the “+” button, click, hold and drag the “button” object to the preview pane. No positioning line appears under the Hit me button as expected. When I release the mouse button, the new button object does not remain on the preview pane and is not added to the code.
What am I doing wrong?
