You can use %@ for all objects including NSString. This will in turn call the objects description method and print the appropriate string.
NSLog method in Objective-C prints out log messages.
In Swift with Xcode you can use either print() or NSLog() . print() just outputs your text.
You can use %@ for all objects including NSString. This will in turn call the objects description method and print the appropriate string. Most objects have a rather useful representation already there (e.g. NSArray objects return the descriptions of all their contents).
