Each exercise includes detailed explanations and sample code to help you understand the concepts and techniques involved. With our exercises, you’ll be well on your way to becoming a skilled Swift developer in no time. Start practicing today and take your skills to the next level!

## Swift Basic Exercises

1. Create a simple calculator that can perform addition, subtraction, multiplication, and division.

2. Create a program that generates a random number between 1 and 100 and prompts the user to guess the number. The program should then inform the user if their guess is too high or too low until they correctly guess the number.

3. Write a program that takes a string input from the user and determines if it is a palindrome (a word or phrase that reads the same backward as forwards).

4. Create a program that generates a random password for the user with a specified length and set of characters.

5. Create a program that takes a list of numbers as input and finds the largest and smallest number in the list.

6. Write a program that takes a sentence as input and converts it to pig Latin (a language game where words in English are altered by moving the first consonant or consonant cluster to the end of the word and adding “ay”).

7. Create a program that takes a user’s name and age as input and prints out a message saying how many years it takes until they turn 100 years old.

8. Write a program that takes a sentence as input and replaces all occurrences of a specific word with another word.

9. Create a program that takes a list of names as input and sorts them alphabetically.

10. Write a program that takes a number as input and prints out the multiplication table for that number up to 10.

Note: These are basic exercises, and you can add more complexity and variation to them.

1. Create a program that uses the Model-View-Controller (MVC) pattern to display a list of items and allows the user to add, edit, and delete items from the list.

2. Write a program that uses the Observer pattern to notify multiple subscribers of changes to a specific object.

3. Create a program that uses the Builder pattern to construct a complex object with multiple options.

4. Write a program that uses the Singleton pattern to ensure that only one instance of a specific object can be created.

5. Create a program that uses the Decorator pattern to add new functionality to an existing object.

6. Write a program that uses the Facade pattern to simplify the interface of a complex system.

7. Create a program that uses the Chain of Responsibility pattern to handle different types of requests.

8. Write a program that uses the Command pattern to implement undo and redo functionality.

9. Create a program that uses the Mediator pattern to control communication between multiple objects.

10. Write a program that uses the Iterator pattern to traverse a collection of objects in a consistent way.

Note: These exercises are more complex, and they are meant to be tackled by developers who have a good understanding of Swift and Design Patterns.
