Objective-C iOS Development for Legacy & Enterprise Apps · Lesson

Working with NSString and Foundation Types

Master Objective-C's core Foundation classes — NSString, NSArray, and NSDictionary — to handle text and collections in legacy iOS apps.

The Foundation Framework

Beyond primitives, Objective-C leans on the Foundation framework for rich objects — most often NSString, NSArray, and NSDictionary.

Creating NSStrings

The @ literal builds an NSString — a full object with many helper methods, unlike a bare C string.

NSString *name = @"Ada Lovelace";
NSLog(@"Name: %@", name);
