Apple formally announced the much-anticipated Worldwide Developers Conference (WWDC) 2021 that will take place from June 7 to June 11.

Due to the pandemic, the Cupertino-based company will have an all-online program for the second time in a row. The program is set to debut the next major iOS update: iOS 15, iPadOS 15, watchOS 8, macOS 12, and tvOS 15.

According to 9to5Mac, Apple CEO Tim Cook announced that last year's event attracted over 22 million viewers. A total of 72 hours of video content was made available to developers. At least 4,500 labs with face-to-face interaction were set up.

There is currently no information available about the configuration of the forthcoming WWDC 2021. Rumors say that the company will most likely unveil the latest iOS updates, new Apple products, and other company news for this year.

"The Apple Worldwide Developers Conference is coming to a screen near you, June 7 to 11. Join the worldwide developer community for an all-online program with exciting announcements, sessions, and labs at no cost. You’ll get a first look at the latest Apple platforms, tools, and technologies — so you can create your most innovative apps and games yet."

Meanwhile, Apple's next macOS updates are highly likely to be launched simultaneously as WWDC 2021 in June. There are also reports that the event will include new hardware announcements for developers and new beta updates.

Apart from software updates, WWDC 2021 is expected to reveal the rumored Apple mixed-reality headset's launch date. Digital Trends said this device will most likely be released in 2022. However, the Apple development team is working nonstop to build this product as soon as possible.

The Apple headset is expected to cost about $3,000, according to reports. However, well-known Apple leaker Ming Chi-Kuo estimated that the product will cost about $1,000.

He also expects the headset to have 15 cameras: eight for augmented reality, one for environmental monitoring, and six for "innovative biometrics."

Meanwhile, the outlet revealed that the much-anticipated Mac transition could happen in June. This is the moment that Apple's latest Apple Silicon processors will be used in Mac devices. New iMacs, MacBook Pros, and other Apple products are on the way, it added.
