What is the "Spray Like" icon in the new MacBook Pro Touch Bar?

There is an icon that looks like a spray can on the right side of the Touch Bar (4th-5th button from the right?)

Does anyone know what it is for?

(Sorry I couldn't find an image of it on the web)


Solution 1:

It seems to be linked to the simulator in Xcode.

the touchbar with spraycan

When pressed this expands into some debugging shortcuts as shown in this screenshot:
