In the recent months following the release of the iPhone 6, iPhone 6S and iPhone 6 Plus, Apple has been enjoying record-breaking sales as the devices have been met with strong customer reception. While other iPhone models have raked in millions for Apple during their respective launch dates, the iPhone 6S has been particularly popular, selling about three million more units during its debut weekend compared to its predecessors.

So it has not been surprising that Apple reported $51.5 billion in revenue from its September quarter, according to a report from Apple Insider. The tech giant has reportedly made 48 million unit sales in iPhones and 5.7 million units in Mac computers. While this is good news from the company, the focus has been given to Apple's projected revenue for the holiday quarter.

Apple estimates a $75.5 to $77.5 billion revenue for its December quarter. Apple's guidance for its holiday quarter revenue has been met by positive responses from analysts and investors. Some investors have been bracing themselves for a decline in iPhone sales, and analyst Gene Munster has called Apple's announcement a 'relief' for those involved. 

Analysts from companies like UBR and JP Morgan have projected that Apple sales will continue to grow in December. As a matter of fact, Apple CEO Tim Cook has expressed that he fully expects Apple's revenue to grow in the last quarter. Some analysts point out that while December may indeed be a good time for Apple, March may not bring in the same results. 

Analyst Stever Milunovich has projected a decline in sales during this time for Apple but said that continuing switchers and the Chinese New Year may help the company's performance. Apple has recently been having a strong showing in China, as market has continued to grow in the country. Wall Street Journal has released Apple's AAPL, which can be viewed here.
