Do you plan to get started in Mac development, especially with SwiftUI?

I'm by no mean Mac expert, but I've made quite a few Mac apps and I've bookmarked some useful resources and tools along the way.

Since many have asked me for recommendation, here is the list 🧵👇

🖥 First of all, how is macOS different from other platforms like iOS, tvOS and watchOS?

Each device has different capabilities and is meant for different purposes.

The Mac is:
- Flexible
- Focused
- Expensive
- Capable

🖥 Human Interface Guidelines

The above 4 points are the distinct theme of Mac, and is from the Human Interface Guidelines, or HIG for short.

Be sure to check it to learn more about macOS design decisions. developer.apple.com/design/human-i…

Have you started leveraging the power of ML in your apps?

While browsing through GitHub for inspirations, I've bookmarked these awesome 20+ open-source machine learning projects

Bring magic to your apps 🧵

⚡️ TensorFlow

The latest version of TensorFlow supports Keras, which is a high-level neural networks API, written in Python and capable of running on top of TensorFlow, CNTK, or Theano.

There are also interfaces for Javascript and Swift.

tensorflow.org

⚡️ scikit-learn

Scikit-learn has simple and efficient tools for data mining and data analysis, built on NumPy, SciPy, and Matplotlib.

It’s a popular choice to use alongside TensorFlow because of its simplicity and handy functions. scikit-learn.org

Recently I've started reviewing system design and algorithms. While this is not for interview purposes, I find that this knowledge helps in both daily job and indie projects.

Below are a few resources that I've learned and I highly recommend. Thread 👇

1) System Design

System design is about defining architecture and modules interface to satisfy requirements. Whether you're working in a team or solo, clarifying requirements on what you want to do and what is exactly the problem, is most important.

2) System Design concepts

You don't need a CS degree to get started, but by reviewing system design, you know these concepts, which you need everywhere you go

📦 Database: SQL vs NoSQL
🗃 Cache
🥊 Scaling
🗳 CND, Load Balancing, Proxying
🎻 Connection: TCP, Polling, Socket

SwiftUI ViewBuilder is resultBuilder, and from Swift 5.3 you can declare if let, if case, multiple if statements, switch, ... pretty much like a normal block function.

ViewBuilder is recommended to leverage SwiftUI type system to ensure performance. Here are a few examples 👇

Local variables.

Pretty much like a normal function, you can declare local variables and return View at last.

Mix if and switch statements

This is handy when you want to show modal or overlay of different Views
