Learn how to print textual representations of data to the standard output, using string interpolation, literal expressions, and various print options.
- I'm continuing on in the playground from the last video.…Printing info to the console is a fundamental…aspect of programming in any language,…and something I'll do frequently throughout the course.…I'll touch upon a couple of things here…that I haven't covered yet.…So if you're following along on your playground…go ahead and just type out the code…as you sere it here for now,…and I'll get into the details later in the course.…The Swift Standard Library includes the print function…which is used to print a textual representation…of a value to the standard output,…in other words, the console here.…If you're coming from Objective C,…think of print as an alternative to NSLog.…
NSLog is still available and a great choice…if you want to include a time stamp in your printout.…Print automatically prints a new line character at the end.…Print can print multiple items passed to it…in a comma separated list too,…such as the hello and playground variables…I defined earlier.…And it will print them out on one line…separated by a space and terminate the string…
