I couldn't initiate IntelliSense for a very long time because I couldn't (too lazy) find any Keyboard shortcuts for 'IntelliSense'. Too bad I already use that as a Spotlight Search. You can also find a list of the analyzers here and if you are interested in learning more visit this blog post or jump directly to this part of the Unite Now talk.By default the shortcut to trigger intellisense on VS Code (for mac) is ⌃ – Control + Space. It’s the sum of all parts when looking into performance optimization and Analyzers can make it easy to help you identify and improve your performance simply by reducing the unneeded overhead by optimizing the code syntax. While the above example represents a minor optimization tweak with no significant impact in a single script attached to a single GameObject, this may be different for a large scale project with 1000s of GameObjects with the script attached.

In this case, the analyzer would suggest the CompareTag method which is more efficient. The analyzer would be able to analyze your code, will detect the pattern and offer to use the more optimized method instead. An example could be a simple conditional statement where you need to check if the GameObject has a specific tag to apply a certain behavior to it. Analyzers can provide you with a better understanding of Unity-specific diagnostics or simply help your project by removing general C# diagnostics that don’t apply to Unity projects. Unity Analyzers are a collection of Unity-specific code diagnostics and code fixes that are open source and available on GitHub. An analyzer works by detecting a code pattern and can offer to replace it with a more recommended pattern. Visual Studio 2019 introduces Unity Analyzers.
