SwiftCalc

SwiftCalc is a modern and elegant calculator app built with SwiftUI. This app provides basic arithmetic operations in a clean, user-friendly interface, and includes features such as percentage calculations and sign inversion.

Features

• Basic Arithmetic Operations: Perform addition, subtraction, multiplication, and division.
• Percentage Calculation: Easily convert numbers to percentages.
• Sign Inversion: Toggle the sign of numbers.
• Clear Function: Quickly reset the calculator.
• Decimal Support: Handle decimal numbers in calculations.
• User-friendly UI: A clean and intuitive interface designed with SwiftUI.
• Responsive Design: Optimized for both iPhone and iPad screens.

Technologies Used

• Swift: The programming language used to build the app.
• SwiftUI: A framework for building the user interface.

Core Logic

Button Actions

• AC: Clears all inputs and resets the calculator.
• +/-: Inverts the sign of the current input number.
• %: Converts the current input number to a percentage.
• Arithmetic Operators (/ x - +): Sets the operation and prepares for the next input.
• =: Calculates the result based on the current operation and inputs.
• Decimal Point: Allows for decimal number input.
• Number Buttons: Appends the pressed number to the current input.

Calculation Logic

• First Number Storage: Stores the first number when an operation button is pressed.
• Second Number Storage: Stores the second number when the equals button is pressed.
• Operation Handling: Performs the arithmetic operation when the equals button is pressed and displays the result.

Project Structure

• ContentView.swift: The main SwiftUI view containing the user interface and logic.
• buttonPressed(_:): Handles the logic for each button press.
• calculateResult(): Performs the calculation based on the current operation and inputs.
• buttonWidth(_:) & buttonHeight(): Calculate the dimensions of the buttons for a responsive design.
• buttonColor(_:): Determines the color of each button based on its function.
