## Tob - Simple Tool Boxes iOS

Developing for iOS is a challenging yet rewarding experience. The platform's robust framework, intuitive user interface, and vast ecosystem of devices make it a prime target for developers looking to build innovative and engaging applications. However, even seasoned iOS developers face repetitive tasks and boilerplate code that can slow down the development process and detract from focusing on the core features of their app. This is where toolboxes, specifically simple, purpose-built ones like "Tob," can be invaluable.

Tob, short for (and intended to represent) a collection of simple, practical tools, aims to address this issue by providing a set of focused utility functions and classes that streamline common iOS development tasks. It's not intended to be a comprehensive framework like UIKit or SwiftUI, but rather a collection of lightweight tools designed to integrate seamlessly into existing projects and offer immediate productivity gains. Think of it as a developer's well-organized toolbox, filled with the essential gadgets needed to quickly handle common tasks.

**What problems does Tob aim to solve?**

Tob targets several key pain points experienced by iOS developers, including:

* **String Manipulation:** iOS development often involves working with strings, whether it's formatting dates, validating user input, or parsing data from external sources. Tob provides utilities for common string operations like trimming whitespace, checking for valid email addresses, capitalizing text, and encoding/decoding URLs, reducing the need to write repetitive code for these tasks.
* **Date and Time Handling:** Dealing with dates and times can be complex, especially when handling time zones, different date formats, and calendar calculations. Tob offers utilities for formatting dates into human-readable strings, converting between different date formats, calculating time intervals, and determining if a date falls within a specific range. This simplifies date and time manipulation, making it easier to build date-aware applications.
* **Data Validation:** Validating user input is crucial for ensuring data integrity and preventing errors. Tob includes utilities for validating common data types like email addresses, phone numbers, URLs, and credit card numbers. These utilities can be easily integrated into form validation logic, providing a consistent and reliable way to validate user input.
* **Networking:** While `URLSession` provides the foundational networking layer in iOS, making simple network requests can still involve writing boilerplate code. Tob simplifies common networking tasks by providing wrapper functions for making GET, POST, PUT, and DELETE requests. It also handles common tasks like encoding URL parameters, setting request headers, and parsing JSON responses. This reduces the complexity of network communication and makes it easier to integrate with web services.
* **UI Utilities:** Small, helpful UI enhancements can dramatically improve the user experience. Tob might include extensions for common UI elements like `UILabel` and `UIButton` to simplify tasks like adding rounded corners, setting custom fonts, and displaying placeholders. It could also include helper functions for displaying alerts, action sheets, and custom modal views.
* **Data Persistence:** While Core Data and Realm offer robust data persistence solutions, sometimes a simpler approach is needed for storing small amounts of data. Tob might include utilities for reading and writing data to `UserDefaults` or the file system, providing a quick and easy way to persist application settings or small datasets.

**Design Principles of Tob:**

Tob is designed with the following principles in mind:

* **Simplicity:** The core principle behind Tob is simplicity. The tools should be easy to understand, use, and integrate into existing projects. The API should be intuitive and self-documenting, minimizing the learning curve for new users.
* **Lightweight:** Tob is designed to be lightweight and efficient. It should not add unnecessary overhead to your application. The tools should be optimized for performance and memory usage.
* **Extensibility:** While Tob provides a set of core utilities, it should also be extensible. Developers should be able to easily add their own custom tools to the toolbox.
* **Testability:** Each tool in Tob should be thoroughly tested to ensure its reliability and correctness. Unit tests should cover all common use cases and edge cases.
* **Documentation:** Comprehensive documentation is essential for making Tob easy to use and understand. Each tool should be well-documented with clear examples and explanations.

**Example Use Cases:**

Here are some examples of how Tob could be used in real-world iOS projects:

* **E-commerce App:** Use Tob's string validation utilities to validate credit card numbers and email addresses during checkout. Use its date formatting utilities to display order dates and estimated delivery times. Use its networking utilities to make API calls to process payments and track shipments.
* **Social Media App:** Use Tob's string manipulation utilities to trim whitespace from user input and encode URLs for sharing content. Use its UI utilities to display user profiles and format timestamps. Use its data persistence utilities to store user preferences and settings.
* **Productivity App:** Use Tob's date and time handling utilities to schedule tasks and set reminders. Use its networking utilities to synchronize data with cloud services. Use its data validation utilities to ensure data integrity and prevent errors.
* **Gaming App:** Use Tob to handle localization of game text. Validate player names and other input to prevent exploits. Persist game state and player progress using simple file I/O tools.

**Potential Components of Tob:**

Here's a breakdown of potential components that could be included in the Tob toolbox:

* **String Extensions:**
* `trim()`: Removes leading and trailing whitespace from a string.
* `isValidEmail()`: Checks if a string is a valid email address.
* `isValidPhoneNumber()`: Checks if a string is a valid phone number.
* `isValidURL()`: Checks if a string is a valid URL.
* `urlEncode()`: Encodes a string for use in a URL.
* `urlDecode()`: Decodes a string from a URL.
* `capitalizeFirstLetter()`: Capitalizes the first letter of a string.

* **Date Extensions:**
* `toString(format: String)`: Formats a date into a string using a specified format.
* `timeIntervalSinceNow()`: Calculates the time interval between a date and the current date.
* `isWithinRange(startDate: Date, endDate: Date)`: Checks if a date falls within a specified range.

* **UI Extensions:**
* `UILabel.setRoundedCorners(radius: CGFloat)`: Adds rounded corners to a `UILabel`.
* `UIButton.setCustomFont(fontName: String, size: CGFloat)`: Sets a custom font for a `UIButton`.
* `UIViewController.showAlert(title: String, message: String)`: Displays an alert with a specified title and message.

* **Networking Utilities:**
* `get(url: String, parameters: [String: Any]?, completion: @escaping (Data?, Error?) -> Void)`: Makes a GET request to a specified URL.
* `post(url: String, parameters: [String: Any]?, completion: @escaping (Data?, Error?) -> Void)`: Makes a POST request to a specified URL.

* **Data Persistence Utilities:**
* `UserDefaults.setObject(forKey: String, value: Any)`: Sets an object in `UserDefaults` for a specified key.
* `UserDefaults.getObject(forKey: String)`: Retrieves an object from `UserDefaults` for a specified key.
