⚡️ Concurrency Programming

I conducted several tests to utilize GCD more effectively.

First, I modified a code snippet that applies a gradient border to a view using CAGradientLayer. By moving the object creation and adjustments to a Global queue, I was able to reduce the execution time from approximately 0.004 seconds to 0.001 seconds.

Second, I optimized multiple API calls in the splash screen using DispatchGroup, allowing concurrent execution. As a result, the total execution time was reduced from approximately 1.4 seconds to 0.4 seconds.

Takeaway: Concurrency programming proves to be particularly beneficial in tasks such as loading multiple images or handling multiple API requests simultaneously.

🙋🏻‍♂️ Other Notes

  1. Useful public portal sites:
  2. A HeatMap is a visualization technique that represents data density or magnitude using colors. A GeoHeatMap is a form of a heatmap applied to a map.
  3. I explored features in Figma, a tool commonly used when collaborating with designers. Learning about Components, Widgets, and Auto Layout in Figma can greatly enhance communication and UI development.
  4. I watched SwiftUI tutorials on the KavSoft YouTube channel and created a GitHub repository while binge-watching lessons 1 to 20.
