Generate the list yourself:

$ cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS*.sdk/System/Library/Frameworks/UIKit.framework/Headers
$ grep UI_APPEARANCE_SELECTOR ./*     | \
  sed 's/NS_AVAILABLE_IOS(.*)//g'     | \
  sed 's/NS_DEPRECATED_IOS(.*)//g'    | \
  sed 's/API_AVAILABLE(.*)//g'        | \
  sed 's/API_UNAVAILABLE(.*)//g'      | \
 sed 's/UI_APPEARANCE_SELECTOR//g' | \

Threads

Foundation offers a Thread class, internally based on pthread, that can be used to create new threads and execute closures.

// Detaches a new thread and uses the specified selector as the thread entry point.
Thread.detachNewThreadSelector(selector: Selector>, toTarget: Any, with: Any)

// Subclass
class MyThread: Thread {

1. Using ZSH in your Terminal

MacOS Catalina has changed the default terminal from Bash to ZSH. As a result, we'll be adding configs to ~/.zshrc instead of ~/.bash_profile like we used in the past. You can manually change from Bash to ZSH anytime by running the following command:

chsh -s /bin/zsh

2. Install Homebrew

First, we need to install Homebrew. Homebrew allows us to install and compile software packages easily from source. Homebrew comes with a very simple install script. When it asks you to install XCode CommandLine Tools, say yes. Open Terminal and run the following command:
