Discussion
You can pass zero or more items to the print(_: function. The textual representation for each item is the same as that obtained by calling String(item). The following example prints a string, a closed range of integers, and a group of floating-point values to standard output:
print("One two three four five")
// Prints "One two three four five"
print(1...5)
// Prints "1...5"
print(1.0, 2.0, 3.0, 4.0, 5.0)
// Prints "1.0 2.0 3.0 4.0 5.0"
To print the items separated by something other than a space, pass a string as separator.
print(1.0, 2.0, 3.0, 4.0, 5.0, separator: " ... ")
// Prints "1.0 ... 2.0 ... 3.0 ... 4.0 ... 5.0"
The output from each call to print(_: includes a newline by default. To print the items without a trailing newline, pass an empty string as terminator.
for n in 1...5 {
print(n, terminator: "")
}
// Prints "12345"
