Origin#
Swift and TypeScript are languages that can be used to develop iOS applications, develop Mac applications, and develop server-side applications.
Due to work and personal interest, I find Swift and Kotlin very interesting and am motivated to learn related knowledge. My goal is to be able to read and write simple logic and complete some simple functions with the help of AI, without needing to become a full-time developer.
With this goal in mind, I began to try to learn about the Swift ecosystem.
Information Filtering#
I looked at the iOS roadmap on roadmap.sh and found it a bit difficult to understand, with many terms that made me dizzy in this new field. The official documentation in Chinese is not particularly comprehensive. The comfort zone of front-end development feels better.
I quickly searched for some keywords on video sites and learning websites, and looked for some Chinese documentation on Baidu and Google. I quickly skimmed through and filtered a wave of information, finally determining a few targets.
- Initially, I won't look at English, only Chinese, and won't read everything one by one.
- Combine video and text, switching states at any time; watching too many videos or texts can lead to fatigue.
- Quick reference, not seeking deep understanding, just familiarity, and asking AI for technical details.
In the end, I found:
- A systematic course on Swift core technologies and practical skills.
- A translation of the Swift language itself.
- Official English documentation https://www.swift.org/getting-started/
- The Swift Programming Language claimed by the author: possibly the most dedicated translation.
- GPT-4o-mini
- No rush to look at the official UIKit and SwiftUI.
Preliminary Results#
I quickly learned and practiced:
- How to run Swift: playground and Xcode projects, related [[How to quickly learn and test Swift and UIKit code?]]
- Basic data structures, common logical judgment syntax, functions, classes, and OOP.
- Third-party dependency management, introducing third-party packages to initiate network requests, JSON processing.
With this foundational knowledge, I feel more confident. I revisited the roadmap.
