You can drag and drop in the iOS simulator by clicking and holding an item. The item “pops” and you can then drag it to a destination. Today, an Apple engineer shared a neat way to free up a “second finger” during this process.
Pause and press the control key. This pins an item mid-drag, enabling you to use the Mac cursor as another touch. You can then retrieve your drag by grabbing the paused item and conclude your drop.
