AdaptiveStack is a concept commonly used in software development to create flexible and adaptive data structures that can grow and shrink dynamically. However, in the context of the Apple environment, particularly macOS and iOS development, the term "AdaptiveStack" is not a standard or widely recognized term. Instead, Apple developers often use data structures provided by Swift and Objective-C, such as arrays, dictionaries, and sets, which can dynamically adjust their size.

In this article, we will explore how to create and manage dynamic data structures in Swift, which is the primary programming language for Apple development. Understanding how to use these structures effectively is crucial for developing robust and efficient applications on macOS and iOS.

Examples:

1. Dynamic Arrays in Swift:

import Foundation

// Creating a dynamic array
var dynamicArray: [Int] = []

// Adding elements to the array
dynamicArray.append(1)
dynamicArray.append(2)
dynamicArray.append(3)

// Removing an element from the array
dynamicArray.remove(at: 1) // Removes the element at index 1

// Iterating through the array
for element in dynamicArray {
    print(element)
}

2. Dynamic Dictionaries in Swift:

import Foundation

// Creating a dynamic dictionary
var dynamicDictionary: [String: Int] = [:]

// Adding key-value pairs to the dictionary
dynamicDictionary["One"] = 1
dynamicDictionary["Two"] = 2
dynamicDictionary["Three"] = 3

// Removing a key-value pair from the dictionary
dynamicDictionary.removeValue(forKey: "Two")

// Iterating through the dictionary
for (key, value) in dynamicDictionary {
    print("\(key): \(value)")
}

3. Using Sets for Unique Collections:

import Foundation

// Creating a dynamic set
var dynamicSet: Set<Int> = []

// Adding elements to the set
dynamicSet.insert(1)
dynamicSet.insert(2)
dynamicSet.insert(3)
dynamicSet.insert(1) // Duplicate elements are not added

// Removing an element from the set
dynamicSet.remove(2)

// Iterating through the set
for element in dynamicSet {
    print(element)
}

These examples illustrate how to create and manage dynamic data structures in Swift, which can be used to achieve similar functionality to what might be referred to as an "AdaptiveStack" in other programming environments.
