SimulatorServices allows you to execute subcommands to simctl directly in Swift while offering an easy to use API for parsing and passing arguments.

SimulatorServices uses the SimCtl object to pass subcommands. Each subcommand objects takes custom arguments or property and can parse the standard output into an easy to use Swift object. There are currently two supported subcommands: GetAppContainers and List.

Share your local development server easily with your Apple devices.

When you are developing a full stack Swift application, you want to easily test and debug your application on both the device (iPhone, Apple Watch, iPad, etc...) as well as your development server. If you are using simulator then setting your host server to localhost will work but often we need to test on an actual device. You can either be an IT expert your local network's DNS or you can use Sublimation to easily connect your local server to your device.

Livestream Your Health Stats Straight From Your Apple Watch

Heartwitch is a combination Apple Watch and Web App for sharing your health data online.

Video game live streaming has become a mainstream form of entertainment, with viewers liking to see how streamers behave and react to gameplay. With Heartwitch, viewers can see how the streamer reacts on a physical level.

See the streamer’s heart rate shift when hiding from a monster, driving a racecar around a tight bend, or as their favorite character dies in their arms.

Unlike other apps that capture user health data, there is no need for extra hardware. It uses the built-in sensors of the Apple Watch to detect your heart rate and send it through our servers directly to your web browser.

Reactive communications library across Apple platforms.

For easier use in reactive user interfaces, especially with SwiftUI and Combine, I've created a library which abstracts and maps common connectivity APIs. Particularly in my app Heartwitch, I mapped the functionality of WatchConnectivity and Network over to track the user's ability to connect to the Internet as well as the ability for their iPhone to connect to their Apple Watch via WatchConnectivity

Swift Package for using Base32Crockford Encoding for Data and Identifiers.

ThirtyTo provides a way to encode data and create identifiers which is both efficient and human-readable. While Base64 is more efficient it is not very human-readable with both both upper case and lower case letters as well as punctuation.

Base32Crockford offers the most reasonable compromise when it comes to encoding data. Being a super set of Base16, it uses all ten digits and 22 of the 26 Latin upper case characters.
