Apple's free cash flow has shown a volatile trend over the past decade. The latest data indicates a significant increase in free cash flow to $128.13 billion in 2022. However, the company experienced a decline in free cash flow in 2016 and 2017, which may be attributed to the launch of new products and increased investment in research and development. Overall, Apple's ability to generate cash through its core operations remains strong, as evidenced by its positive free cash flow performance.
