①You can copy it. For example, you can assign it to a new variable.
②You can pass it as a parameter to a function or method.
③You can compare it with another value to see if the two values are equal.
To understand any programming language, you must understand how these three operations are implemented in this l

that you don't need to memorize the order, as long as you have a name.
However, if you want to extract more than one element from the list, you can only extract individual elements using single brackets (both brackets and dollar signs), and you know the order.

The difference between the two brackets and the dollar sign:
The dollar sign must be the element name that exists in the list;
The two brackets can be after the subsequent assignment variable

Today's blog summarizes some of the two new data types added in Swift relative to OBJC: tuple (tuple) and optional value type (Optional). The above two types are unique to Swift, and are very handy to use today, with examples that describe how to initialize and use tuples and optional value types, and scenarios that use tuples and optional value types. Talk less, go straight to the topic, and still test using playground in today's sample code. The lef
