My iPad app has a View that makes use of a Steel shader as described right here.
#embody <metal_stdlib>
utilizing namespace metallic;
[[ stitchable ]] half4 borderField(float2 place, half4 currentColor, float2 measurement, half4 newColor) {
assert(measurement.x >= 0 && place.x <= measurement.x);
assert(measurement.y >= 0 && place.y <= measurement.y);
// Compute distance to frame
float dt = measurement.y - place.y; // Distance to prime
float db = place.y; // Distance to backside
float dl = place.x; // Distance to left
float dr = measurement.x - place.x; // Distance to proper
float minDistance = min(min(dt, db), min(dl, dr));
float r = minDistance + 1.0;
float power = 1.0 / sqrt(r);
return half4(newColor.rgb, power);
}
It’s utilized to my View utilizing the next modifier:
.colorEffect(ShaderLibrary.fields(.floatArray(viewModel.floatArray)))
The app can use any system orientation.
If I launch it in portrait orientation, the View is displayed accurately:
If I flip the simulator left and launch the app in panorama orientation, the next error is logged:
RBLayer: unable to create texture: BGRA8Unorm, [8.196, 5.200]
and the View will not be coloured:
If I flip the simulator again to portrait mode whereas the app is working, the View is once more coloured accurately.
Nevertheless, if I flip it left once more whereas the app is working, I get as soon as extra the identical error, however the View seems to be now in another way:
I haven’t got expertise in Steel programming, and I do not know what’s mistaken.
There are 2 posts that report the same error, however apparently they don’t apply to my case: This one, and this one.
Any strategies?
