# resolveCounters(_:range:destinationBuffer:destinationOffset:) Encodes a command that resolves the data from the samples in a sample counter buffer and stores the results into a buffer. ``` func resolveCounters(_ sampleBuffer: any MTLCounterSampleBuffer, range: Range, destinationBuffer: any MTLBuffer, destinationOffset: Int) ``` ## Parameters `sampleBuffer` A counter sample buffer source that contains the sample data. `range` A range that indicates which of the buffer’s samples the command resolves. `destinationBuffer` A destination buffer where the command stores the data it resolves. `destinationOffset` A starting offset, in bytes, within `destinationBuffer` where the blit pass writes the first byte of the data it resolves. ## Discussion For an example of how and when to use this method, see [Converting a GPU’s counter data into a readable format](/documentation/Metal/converting-a-gpus-counter-data-into-a-readable-format). > Note: > The GPU stores ``doc://com.apple.metal/documentation/Metal/MTLCounterErrorValue`` in `destinationBuffer` each time it encounters an error resolving a sample. --- Copyright © 2026 Apple Inc.
