Look for ready-made functions in Swift, for example, the print function
What are the pre-defined and ready-made functions in Swift, and which are most commonly used?
What is the work of each function?
Ready functions
Swift has a standard library and a number of libraries, like Foundation, that are available on all Swift platforms. Swift can also use system libraries from the platform on which it’s running. For example, on iOS you can use UIKit and on macOS you can use AppKit.

There’s no easy way to answer that; it very much depends on your specific goals.

@dera There are a lot of func.
Some are "generic" as print, others for certain object type: such as map, filter, reduce for collection types, or replace, find, … for Arrays or Strings….
So the question should be asked the other way: what are you looking for ? Is there a Swift func for that task ?
A good way to answer is:
- look in Xcode doc
- search in Swift language reference
- ask the web…
