About this Episode

Welcome to Code Completion, Episode 53! We are a group of iOS developers and educators hoping to share what we love most about development, Apple technology, and completing your code!

Follow us @CodeCompletion on Twitter to hear about our upcoming livestreams, videos, and other content.

Today, we discuss:

  • Code Completion Club: https://codecompletion.io/jointheclub
  • Indie App Spotlight, with a new app for you to check out:
  • Our interview with special guest Matt Ronge, co-founder and creator of Astropad and Luna Display!
  • Questions:
    • How did you get started with development?
    • What were you doing pre-Astropad?
    • How did it come about?
    • How did you build a business off of Astropad?
    • What was the inspiration that lead into Luna?
    • How did you grow your team?
    • Why Windows?
    • How different is Rust?
    • Why not Swift?
    • How did the Windows release go?
    • What’s next?

Also, join us for #CompleteTheCode and Compiler Error, two segments that test both your knowledge and our knowledge on Swift, Apple, and all things development!

Compiler Error

This week's Compiler Error has a theme: Latest Display Technologies
1 - Thunderbolt 4 not only supports DisplayPort 2.0, but also allows the full 80 Gbps to be dedicated for video output, allowing 8K displays up to a whopping 240 fps.
2 - DisplayLink allows displays to be connected over USB or ethernet by using an adapter that transforms the data signal into a DisplayPort or HDMI signal.
3 - SDI, or serial digital interface, is the preferred connection on film sets connecting cameras to recording equipment, and allows for up to 48 Gbps over a single connection.
4 - Also limited to 48 Gbps, HDMI 2.1 supports HDR10 footage of up to an 8K resolution at 120 Hz on supported cables.
