Hello, I'm going to use C's 2d array in my shaders. The reason is to use 2d index in buffer, instead using textures. Someone from the developers can dissuade me from doing this? #include <metal_stdlib> using namespace metal; struct DebugCell {     float4 info; }; struct DebugBuffer {     DebugCell cells[5][3]; // Column number(x), Row number(y). (x, y)  }; kernel void debugCells(device DebugBuffer *current [[buffer(0)]], uint2 id [[thread_position_in_grid]]) {     current[0].cells[id.x][id.y].info.xy = float2(id); } /*  after reshape for printing on CPU it prints  [[0.0,0.0], [1.0,0.0], [2.0,0.0], [3.0,0.0], [4.0,0.0], [5.0,0.0], [6.0,0.0], [7.0,0.0]]  [[0.0,1.0], [1.0,1.0], [2.0,1.0], [3.0,1.0], [4.0,1.0], [5.0,1.0], [6.0,1.0], [7.0,1.0]]  [[0.0,2.0], [1.0,2.0], [2.0,2.0], [3.0,2.0], [4.0,2.0], [5.0,2.0], [6.0,2.0], [7.0,2.0]]  */

Hello. How does V/HStack update on Avatar Picker App (The Contacts App) on macOS so smoothly? Can you share some source code, please?

I am trying modeling run loop in a simple project. Could you post the source code of RunLoop?

subj And how in this case are beautiful system dials made with smoke effects and other particles?
