Tech Stack

• Xcode: Version 15.3
• Language: Swift 5.10
• Minimum iOS Version: 13.0
• Dependency Manager: SPM

Architecture

In developing Getir Final Project, VIPER (View-Interactor-Presenter-Entity-Router) architecture is being used for these key reasons:

• Clear Separation: VIPER architecture separates UI, business logic, and navigation for cleaner, more maintainable code.
• Test-Driven Development: VIPER's modular structure enables comprehensive unit testing, ensuring app stability.
• Scalability: VIPER's modular design allows easy addition of features and modifications.

Unit Tests

• All of the presenters and interactors of every module
• CartService
• SwiftAsyncNetworking, GetirSDK (my own local SPMs) are tested.

Getting Started

Prerequisites

Before you begin, ensure you have the following:

• Xcode installed

Also, make sure that these dependencies are added in your project's target:

• Kingfisher: Kingfisher is a lightweight and pure Swift library for downloading and caching images from the web.
• SwiftAsyncNetworking: My own local package for concurrent networking. (Available documentation in project directory)
• GetirSDK: My own local package to mimic the GetirService. (Available documentation in project directory)

Installation

1. Clone the repository:

   git clone https://github.com/lochmidth/GetirFinalProject.git

2. Open the project in Xcode:

   cd GetirFinalProject
   open GetirFinalProject.xcodeproj

3. Add required dependencies using Swift Package Manager:

   - Kingfisher
   - SwiftAsyncNetworking (local)
   - GetirSDK (local)

4. Build and run the project.

Known Issues

• When updating BasketViewController by adding or removing product from cart, UI flicks for a really short time due to collectionView.reload()

Improvemets

• A more pleasent and seamless animations can be add for a better user experience.
• Localization for other languages can be added to be able to reach more user.
• Consolidate CartService into GetirSDK to adhere more closely to the SOLID principles, particularly the Single Responsibility Principle.
