One ominous sign in particular was that Cognex, which sells technologies to factories that assemble iPhone X and generates 20 percent of its revenue from Apple, reported disappointing first-quarter earnings on Monday.
For the quarter ending 31 March, Apple posted a net profit of $13.8bn (£10.1bn), up from last year's $11bn (£8.1bn).
Apple also reported sales of 52.2 million iPhones for the three months to the end of March, up from 51 million a year earlier - only just missing a Wall Street target of 52.3 million. For instance, the iPhone 8, iPhone 8 Plus and Apple Watch Series 3 was launched in India just a week after it went on sale in the US. Global sales accounted for 65 percent of the quarterly revenue. This will be a way of returning money to investors as Apple stock rises, in a bid to show confidence in its iPhone range.
Apple does not offer sales figure from Apple Watch, AirPods and other peripherals but it did confirm revenues from other products were up 38 percent from previous year.
Apple previously promised to hire 20,000 more workers during the next five years, including some at a planned new campus in a still-to-be-identified U.S. city outside California.
Thanks to its strong results, the company has hiked up its quarterly dividend to shareholders by 16 per cent and announced a new $100bn share repurchase authorisation. The firm's services also grew, with Apple Music, iCloud, Apple Pay among others all cumulatively soaring by more than 30 percent, bringing in 9.2 billion dollars in revenue. There's obviously huge opportunities for us and we have an extremely low share in that market overall.More news: Pimp My Royal Ride: Preparing the Wedding Carriages

The hardware sales, together with nearly $10 billion worth of services, translated into revenue of $61.1 billion, and $13.8 billion profit, in line with Apple's own revenue guidance.
However, Cook said iPhone X is the best-selling smartphone in China right now. Apple sells more iPhone X units every week than any other iPhone model, and that's been the case since the launch of the device back in November.
The company's Other Products category saw notable year-on-year growth, with revenue reaching $3.9 billion, up from $2.9 billion for the same period last year.
Along with the new authorization, the Board of Directors has also approved a 16% increase in the company's quarterly dividend.
Analysts had feared the iPhone X model's $999 (roughly £730) price tag could have muted demand for the handsets.
