Use SwiftUI preview with UIKit

In my opinion SwiftUI preview is the most useful feature in SwiftUI if you want to work with older version of IOS. In this post I share how I set up my project. 

Create project like showing in the pictures:


Delete the unused ContentView which use the SwiftUI.

Modify AppDelegate as follow.

Create MainView (UIView) and MainViewController (UIViewController). Adding these previews functions into MainView and MainViewController.

Build the project and refresh Canvas. The previews should show now. You can try to change a background color of the ViewController and see the change take effect immediately. Like in the video:

Finally, Link to the code.

My books review: "The retrospective handbook"

Overview: The retrospective handbook is a useful collection of tips for preparing and running retrospective for agile teams. The central point of facilitating a retrospective is the preparation. All the details - even the smallest details such as how much paper is available or what the colours of the using pens - play an important role in running a successful retrospective. In such preparation, the most important preparation is the relationship. It requires team members to have high trust with each other to address any problems in great details and find the most suitable solution for those problems. My impression: The tips for running remote retrospective would be really useful for anyone especially startups in my opinion. All the startups I have worked for so far have had some foreign teams either external or internal to save operating money. In addition, there are a lot of remote work to save office renting space and almost all of those startups followed the agile method.

My books review: Money for the rest of us

Overview: The "Money for the rest of us" book is a list of 10 questions serve as a guideline to invest. It is light book with not many pages and can be read during commute time. The book does not require audiences to have any special knowledge. My impression: The author, Mr. David, is very friendly and patient to answer my questions. The 10 questions are greatly explained by the author, and I think they provide a good starting point. However, I think anyone who wants to invest should build their own checklist and a general guideline for different situations. When a general guideline is in place, the decisions need to respect the guideline in order to make consistent decision. Consistency , in my opinion, is the most important in the long run as it provide information for constant feedback and improvements. Overall, I think this is a good book that helps improving my decision making process. - ninjahoahong

The first taste of Rust - A simple you tube downloader

Recently, I just learnt Rust and using it to write a simple youtube downloader with reference from node-ytdl . In this blog, I would like to share the code and how did I make it. You can find the full source code here . Install development environment I am using Windows 10 and scoop package manager. Therefore, I use the following commands. Run scoop install rustup-msvc to install rustup . Run setx "%path%;%USERPROFILE%\\scoop\\persist\\rustup\\.cargo\\bin" to add rustup to the path. Restart termial (git-bash in my case) and check the installation with rustup --version; rustc --version; cargo --version Export custom RUST_HOME : export RUSTUP_HOME=$HOME/scoop/persist/rustup/.cargo/bin/rustup Install a toolchain for rustup : rustup toolchain install stable-x86_64-pc-windows-msvc Setup project Run cargo new simple_rust_youtube_downloader --bin && cd simple_rust_youtube_downloader to create and navigate to the project.
