MyGym – Fitness Gym App for Coaches, Trainers and PT Classes Created With Swift 4 in Xcode

Introduction

Welcome to the MyGym - Fitness Gym App tutorial! In this comprehensive guide, we will walk you through the process of creating a user-friendly and feature-rich fitness app for coaches, trainers, and personal training classes using Swift 4 in Xcode. The app will allow users to create and manage their own personal training classes, track their progress, and connect with other trainers and coaches.

Getting Started

Before we dive into the tutorial, make sure you have the following:

• Xcode installed on your Mac
• Swift 4 or later installed on your Mac
• A basic understanding of Swift programming language
• A computer with a decent processor and RAM

Step 1: Creating the Project

Open Xcode and create a new project by selecting "Single View App" under the "iOS" section. Name your project "MyGym" and choose Swift as the programming language.

Step 2: Setting up the UI

Create a new Swift file called "MyGymViewController.swift" and add the following code:

import UIKit

class MyGymViewController: UIViewController {

    // UI components
    @IBOutlet weak var tableView: UITableView!
    @IBOutlet weak var searchBar: UISearchBar!

    // Data model
    var classes = [Class]()
    var filteredClasses = [Class]()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Set up the UI
        tableView.dataSource = self
        tableView.delegate = self
        searchBar.delegate = self
    }
}

This code sets up a basic UI with a table view and a search bar. We'll add more UI components as we progress through the tutorial.

Step 3: Creating the Data Model

Create a new Swift file called "Class.swift" and add the following code:

import Foundation

struct Class {
    let name: String
    let description: String
    let duration: Int
    let intensity: String
    let trainer: String
}

This code defines a Class struct that will hold the data for each personal training class.

Step 4: Populating the Data Model

Create a new Swift file called "MyGymData.swift" and add the following code:

import Foundation

class MyGymData {
    static let sharedInstance = MyGymData()

    var classes: [Class] = []

    func loadClasses() {
        // Load the classes from a database or API
        classes.append(Class(name: "Cardio Kickboxing", description: "Get fit and have fun with our cardio kickboxing class!", duration: 60, intensity: "High", trainer: "John Doe"))
        classes.append(Class(name: "Yoga", description: "Relax and stretch with our yoga class!", duration: 45, intensity: "Low", trainer: "Jane Smith"))
        //...
    }
}

This code defines a MyGymData class that will hold the data for the personal training classes. We'll load the classes from a database or API in the loadClasses() method.

Step 5: Displaying the Data

Modify the MyGymViewController class to display the data:

import UIKit

class MyGymViewController: UIViewController {

    // UI components
    @IBOutlet weak var tableView: UITableView!
    @IBOutlet weak var searchBar: UISearchBar!

    // Data model
    var classes = [Class]()
    var filteredClasses = [Class]()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Set up the UI
        tableView.dataSource = self
        tableView.delegate = self
        searchBar.delegate = self

        // Load the classes
        MyGymData.sharedInstance.loadClasses()
        classes = MyGymData.sharedInstance.classes
        filteredClasses = classes
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return filteredClasses.count
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "ClassCell", for: indexPath)
        let classItem = filteredClasses[indexPath.row]
        cell.textLabel?.text = classItem.name
        return cell
    }
}

This code loads the classes from the MyGymData class and displays them in the table view.

Step 6: Implementing Search

Modify the MyGymViewController class to implement search:

import UIKit

class MyGymViewController: UIViewController {

    // UI components
    @IBOutlet weak var tableView: UITableView!
    @IBOutlet weak var searchBar: UISearchBar!

    // Data model
    var classes = [Class]()
    var filteredClasses = [Class]()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Set up the UI
        tableView.dataSource = self
        tableView.delegate = self
        searchBar.delegate = self

        // Load the classes
        MyGymData.sharedInstance.loadClasses()
        classes = MyGymData.sharedInstance.classes
        filteredClasses = classes
    }

    func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
        filteredClasses = classes.filter { $0.name.lowercased().contains(searchText.lowercased()) }
        tableView.reloadData()
    }
}

This code implements search by filtering the classes based on the search text entered in the search bar.

Step 7: Creating a New Class

Create a new Swift file called "NewClassViewController.swift" and add the following code:

import UIKit

class NewClassViewController: UIViewController {

    // UI components
    @IBOutlet weak var nameTextField: UITextField!
    @IBOutlet weak var descriptionTextField: UITextField!
    @IBOutlet weak var durationTextField: UITextField!
    @IBOutlet weak var intensitySegmentedControl: UISegmentedControl!
    @IBOutlet weak var trainerTextField: UITextField!

    // Data model
    var newClass: Class?

    override func viewDidLoad() {
        super.viewDidLoad()
        // Set up the UI
        nameTextField.delegate = self
        descriptionTextField.delegate = self
        durationTextField.delegate = self
        intensitySegmentedControl.addTarget(self, action: #selector(intensityChanged), for:.valueChanged)
    }

    @objc func intensityChanged() {
        let intensity = intensitySegmentedControl.titleForSegment(at: intensitySegmentedControl.selectedSegmentIndex)
        newClass?.intensity = intensity!
    }

    @IBAction func saveButtonTapped(_ sender: UIButton) {
        // Create a new class
        let newClass = Class(name: nameTextField.text!, description: descriptionTextField.text!, duration: Int(durationTextField.text!)!, intensity: intensitySegmentedControl.titleForSegment(at: intensitySegmentedControl.selectedSegmentIndex)!, trainer: trainerTextField.text!)
        MyGymData.sharedInstance.classes.append(newClass)
        self.dismiss(animated: true, completion: nil)
    }
}

This code creates a new view controller for creating a new class. It includes text fields for entering the class name, description, duration, and trainer, as well as a segmented control for selecting the intensity. When the user taps the "Save" button, a new class is created and added to the data model.

Step 8: Displaying the New Class

Modify the MyGymViewController class to display the new class:

import UIKit

class MyGymViewController: UIViewController {

    // UI components
    @IBOutlet weak var tableView: UITableView!
    @IBOutlet weak var searchBar: UISearchBar!

    // Data model
    var classes = [Class]()
    var filteredClasses = [Class]()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Set up the UI
        tableView.dataSource = self
        tableView.delegate = self
        searchBar.delegate = self

        // Load the classes
        MyGymData.sharedInstance.loadClasses()
        classes = MyGymData.sharedInstance.classes
        filteredClasses = classes
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return filteredClasses.count
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "ClassCell", for: indexPath)
        let classItem = filteredClasses[indexPath.row]
        cell.textLabel?.text = classItem.name
        return cell
    }

    @IBAction func addClassButtonTapped(_ sender: UIButton) {
        // Present the new class view controller
        let newClassViewController = NewClassViewController()
        newClassViewController.modalPresentationStyle =.fullScreen
        present(newClassViewController, animated: true, completion: nil)
    }
}

This code adds a new class button to the table view and presents the new class view controller when tapped.
