Production iOS 15 throws:
"THREE.WebGLProgram: shader error: 1281 35715 false gl.getProgramInfoLog Internal error compiling shader with Metal backend"
When using aframe particle-system component.
Unresolved as of 10/22/21
Github Issue:
https://github.com/IdeaSpaceVR/aframe-particle-system-component/issues/61
note the error codes do not seem to be consistent, but using the particle-system component will cause crashes or blatant shader glitches in iOS15.

Thank you for the report.
Could you link to a simple reproduction? Either a url that runs the particular component or a simple html+js package reproducing the issue?
I could not any examples from the project website with a cursory investigation.

Dup of https://bugs.webkit.org/show_bug.cgi?id=229378
If you need an immediate workaround...
The problem here is that the function name 'and' is conflicting with a metal symbol. We've fixed this in ToT Webkit.
To fix this, rename the 'and' function below to something else.
// float and(float a, float b) {
// return a * b;
