I'm doing a Swift tutorial and there's :
EXPERIMENT
In Xcode, Option-click the name of a constant or variable to see its inferred type. Try doing that with the constants in the code above.
What's Option-click ? And how to do it ?
How to Option-click in Xcode ?
Hi,
It means: hold the "alt ⎇" key on your keyboard while clicking with your mouse on the constant or variable's name.
Which Mac are you using?
Is there a key labeled:
alt
option
...in the bottom row of keys on either side of the space bar?
