MVP price generator

Recommendation app written for iOS from surfers to surfers

Survey by surfers: https://docs.google.com/forms/d/e/1FAIpQLSdzwVMycAc3ISaFck8lxFKnC8e5i4BmnzlVo_N9-Z0lRCYeJg/viewform?usp=sf_link

📌 project requires Xcode 13+ (Swift 5.0)

Deployed for: iOS 14+

Why did you undertake the project?

This was a long passion of mine and I was lucky enough to get a mentorship through a Import Foundation programme where I presented my vague idea at the time. This led me to wonderful collaborations and learning path. Here is the result of Beta V1.0. surf app. It was created from idea: help surfers to learn from surf goals and expectations. Adding value to surf hobby by that extra planning, it is a developers approach to surfing.

Scope / User story

As a surfer I want to set clear surf goal. To accomplish this goal I need a correct sufboard and a location. I choose a level in the app and the date of expected surf and than the app opens the recommended boards and locations. As a surfer I want to buy a new or second hand surfboard but I do not know what kind would be useful for me. I tap claculator and see the choices I have for range I can spend.

Used Libraries

CoreML

SwiftyPickerPopover

SwiftLint

Lottie

Technologies / Stack used

Navigation scheme: MVC + Coordinator manager Using the UIResponder

Illustrates flow of the app: User always needs to come back to the begining- Welcome screen

• Splash screen
• Welcome screen
• Add level flow
• Add date flow
• TabBar Main Coordinator
• Recommendations for trip
• Previous trips - (check a list)
• Calculator for board prices

Linear Regression

CoreML and prediction model for the surfboard prices

List of features

• Recommended surfboards (volume,shape,size) for the user level
• Recommended country locations for season and level
• Preditions for used or new surfboard current market price

Lessons learned

• How simple is to use CoreML and how hard itis to test the model
• The exciting thing about this work is that I had no idea where it would take me. I knew I needed to use Coordinator pattern and that I would not be using a backend for the first version of the app (only mocks).
• I learned how to focus on one main priority thing, and reduce the complexity.
• Building MVP from scratch, kickstart idea-design-tech stack and implementation of it.
• Don't mix SwiftUI with AutoLayout
• App Store upload process

Wish list

• Implement tests for business logic and UI - automatisation
