Tech

This demo uses a number of open source projects to work properly:

• GoogleSignIn-iOS - Enables iOS and macOS apps to sign in with Google.
• GoogleAPIClientForRest - Google API Client in ObjC to fetch API data for google services
• Lottie - An iOS library to natively render After Effects vector animations.
• Core Spotlight - Indexing app so users can search the content from Spotlight and Safari.
• Core Services - Access and manage key operating system services, such as launch and identity services.

And of course this demo app itself is open source with a public repository on GitHub.

Development

Want to contribute? Great!

This app uses SwiftUI + Combine for binding data and creating the UI.

Work In Progress

• Deeplink for events in spotlight
• Optimising indexing of events in spotlight
• Using a Watch for Google calendar instead of timed API calls (Unable to get proper documentation on this in GoogleAPIClientForRest)
