Does Swift manage the memory of a CVPixelBuffer that I create from CVPixelBufferCreate?

Let's say I want to store a frame from camera output

let imageBuffer:CVPixelBuffer = CMSampleBufferGetImageBuffer(sampleBuffer)
some_list.append(imageBuffer.copy())

And here is how the copy function is defined by extension to CVPixelBuffer:

extension CVPixelBuffer {
    func copy() -> CVPixelBuffer {
        precondition(CFGetTypeID(self) == CVPixelBufferGetTypeID(), "copy() cannot be called on a non-CVPixelBuffer")
        var _copy : CVPixelBuffer?
        CVPixelBufferCreate(
            nil,
            CVPixelBufferGetWidth(self),
            CVPixelBufferGetHeight(self),
            CVPixelBufferGetPixelFormatType(self),
            CVBufferGetAttachments(self, CVAttachmentMode.shouldPropagate),
            &_copy)
        guard let copy = _copy else { fatalError() }
        CVPixelBufferLockBaseAddress(self, CVPixelBufferLockFlags.readOnly)
        CVPixelBufferLockBaseAddress(copy, CVPixelBufferLockFlags(rawValue: 0))
        let dest = CVPixelBufferGetBaseAddress(copy)
        let source = CVPixelBufferGetBaseAddress(self)
        let height = CVPixelBufferGetHeight(self)
        let bytesPerRow = CVPixelBufferGetBytesPerRow(self)
        memcpy(dest, source, height * bytesPerRow)
        CVPixelBufferUnlockBaseAddress(copy, CVPixelBufferLockFlags(rawValue: 0))
        CVPixelBufferUnlockBaseAddress(self, CVPixelBufferLockFlags.readOnly)
        return copy
    }
}

The question is: Do I need to explicitly manage the CVPixelBuffer copy I created? Or does Swift take care of it through reference count?

Swift manages your buffer object, so you don't have to consider about releasing it.

Core Foundation objects returned from annotated APIs are automatically memory-managed in Swift—you don't need to invoke the CFRetain, CFRelease, or CFAutorelease functions yourself.

In fact, there is no Swift version of CVPixelBufferRelease function.
