Why Every Swift Developer Needs to Know Stacks

Learn how to build and implement a Stack data structure from scratch in Swift! In this tutorial, we cover the core principles behind Stacks (LIFO - Last In, First Out) and walk step-by-step through implementing custom generic Stack structs in Swift, including essential methods: • push(_:) - Adding elements to the top of the stack • pop() - Removing and returning the top element • top / peek - Inspecting the top element safely • isEmpty & count - Tracking stack state ⏱ Timestamps: 0:00 - Introduction & Real-World Analogy (LIFO) 0:55 - Struct Definition & Generic Elements 2:15 - Implementing the Push Method 3:00 - Implementing Pop with @discardableResult 4:40 - Adding Peek (Top) & Helper Properties If you found this tutorial helpful, don't forget to like, subscribe, and drop a comment with what data structure you'd like to see next! #Swift #iOSDev #DataStructures #SwiftProgramming #CodingInterview
