Curated list of articles, web-resources, tutorials, Stack Overflow and Quora Q&A, GitHubcode repositories and useful resources that may help you dig a little bit deeper into iOS. All the resources are split into sub-categories which simlifies navigation and management. Feel free to use and suggest something to learn (iOS related of course 😜).
You may see some non-directly related topics such as Computer Graphics, Machine Learning or Design Patterns - these are actually related, in some ways, to iOS development, but in a much broader and more specific way. With the addition of new materials, the structure of the document will be properly maintained meaning that it will become a reference book for learning. Happy evolving 🤓:octocat:
