I need a queue of NSStrings in my Obj-C/Cocoa application. What is the easiest way to implement this? Do I have to write my own, or does a data structure already exists?

There's no FIFO or stack structures in Objective-C as such but they are trivial to implement. For a queue/FIFO just use an NSMutableArray, add things with addObject: and remove them, with objectAtIndex:0 followed by removeObjectAtIndex:0 Unless you have a vast number of objects you'll likely never notice that it has to memcpy the stack down one word when you remove the items.
