Apple's iPhone development schedule hit by China lockdowns

Eddie Han, an analyst with Isaiah Research, told Nikkei Asia that lingering restrictions present a hurdle for getting development back on track.

"The resumption of production is not progressing well because there are still a lot of restrictions in terms of living and travel in the greater Shanghai area, even if these production sites can operate in a closed-loop," Han said.

"Currently, we don't think the delay would immediately affect the schedule for the product launch, but we need to monitor closely whether there are some hidden and longer-term impacts."
