Recommendations to improve Lefdili’s project:
– Use a UITabBarController for the main navigation (read documentation about human interface guidelines)
– Add a launch screen
– Adjust colour assets to support dark mode
– Change look of UI to more modern design (check Dribble for design inspirations)
– If you want to build apps without Storyboards in UIKit, have a look at the Coordinator pattern (https://betterprogramming.pub/leverage-the-coordinator-design-pattern-in-swift-5-cd5bb9e78e12)
– Learn about the pro’s and con’s of the Singleton pattern and find alternative implementations (https://matteomanferdini.com/swift-singleton/). Using only Singleton shows that you don’t know how to pass data between view controllers correctly.
– Structure your code to show a clear data flow
– Closures and capturing self can create memory leaks (https://www.swiftbysundell.com/articles/swifts-closure-capturing-mechanics/)

Some tech that should be mentioned in the readme/portfolio website:
– programmatic UI
– UICollectionView and custom UICollectionViewCells
– Design pattern MVVM
– Data flow and storage: Core Data, UserDefaults, Firebase
– Google AdSense
– Localisation in English, French and Arabic
