# WWDC22 Day 5 recap

It's time to close out Day 5 of WWDC with one last report.

## Transcript

♪ Bass-heavy electronic music ♪ It's time for your final report.

♪ First, we covered how to improve battery consumption for your apps.

- Display is one of the major sources of power consumption.

- We learned how to make a Swift Server app alongside an iOS app in Xcode.

- Using Swift for building server components helps bridge this technology gap.

- Then Neil showed us how to match audio catalogs with video using ShazamKit.

- Now we have some important updates that streamline working with custom catalogs at scale.

- We discovered how to create multiple windows for our iPad apps.

- Here's an app I've built to keep track of the books I'm reading.

- And we closed out the week with a friendly device-to-device game of tic-tac-toe.

- And that's how easy it is to connect devices to Apple TV.

- Our training is complete, developers.

You're ready for your mission.
