SwiftUI: How to draw a pixel by SwiftUI?

Forums > SwiftUI

I'm going to write a drawing app, however, I can only find the post about drawing a vector path like Path or Shape. And ChatGPT only give me the solution by using Rectangle to repalce pixel, which cost lots of memory.

Could you give a tip about which API shoud I use.

My goal is to create board of a pixel by b pixel, and when I active a drawGesture, the pixels in the path where my finger passed by be draw on color.

Thank you for you help!
