Tim Cook: Apple Watch Sales Doubled In the Last Quarter

And the results are better than the year-ago Q2, which saw profit of $1.90 per share on $50.6 billion in revenue.

Cook also said Apple plans to put money into programs that will train "the next generation" of app developers, and he plans to announce more about that this summer.

The quarterly profits of Apple were $11 billion worldwide, up 4.9 per cent from the same period in 2016.

The American tech giant said it had sold 50.7m iPhones in the three months to the end of April, 1 per cent below the same period previous year, reports The Telegraph.

Analysts on average expect the company to sell 42.31 million iPhones in the current quarter, according to FactSet.

The new 10-year anniversary iPhone are expected to include features such as wireless charging, 3-D facial recognition as well as a curved display.

Apple CEO Tim Cook told CNBC on Tuesday the company is "seeing a kind of delay in purchasing behavior that we think is a effect of the number of rumors and reports about future products".

Apple's market value fell more than 2% after hours on the Nasdaq.

Apple chief executive Tim Cook said during an investor conference that the "pause" in purchases of the iPhone is linked to the fact that many potential iPhone customers are waiting for the new model to be released in September.

Additionally, the rate at which Apple is retaining USA iPhone users is reportedly on the decline.

"In our view, consumers are becoming aware of the product cycle and we believe this should cause increased seasonality in the product as consumers await updated and fully remade iPhones", said Amit Daryanani, an analyst at RBC Capital Markets.

Earnings per share of US$2.10 were ahead of market expectations of US$2.02 and were up 10.5% from US$1.90 a share the year before.

Maestri said that sales of Macs and the company's services were strong in China during the March quarter. He did not identify the company, but said more about the fund will be announced later this month.
