Here’s the low down on all the products launched tonight by Apple

The X has glass on both the front and the back and “surgical-grade” stainless steel around the sides.

Water-resistant it will come with two colours: grey and silver. It also has the highest pixel density display ever in an iPhone.

The phone measures 5.8 inches in diagonal size.

Apple CEO Tim Cook introduced the phone with the following words:

“Over the past decade, we’ve pushed forward with innovation after innovation, bringing us to this moment, when we can create devices that are far more intelligent, far more capable, and far more creative than ever before.”

The Apple boss called the new device the "future of the iPhone", and announced it will feature new facial recognition technology called Face ID.

It will be the most expensive iPhone ever, costing $999 dollars and going on sale on November 3.

The software uses infrared sensors among others to build a dot pattern and recognise a user’s face through machine learning techniques.

Apple says it can even recognise users in the dark.

As well as being used to unlock the device, Face ID technology can also be used to create Animoji - animated emoji controlled by the user’s face.

The larger screen, which fills the front of the device and replaces the traditional home button, also uses OLED screen technology for the first time.

The Super Retina display screen is now swiped upwards to unlock, with swipes also used to close apps now the home button is gone.

Apple’s Phil Schiller also revealed the dual rear cameras on the X will be 12 megapixel and both will carry optical image stabilisation for the first time.

The front-facing camera now carries Portrait mode and Portrait Lighting technology for the first time, which the firm says will enable users to take better selfies.

Apple also unveiled the new iPhone 8 and 8 Plus were also announced by Apple boss Tim Cook, who called the phones a "huge step forward" for the device.

The two new phones will feature glass on the front and rear of the device for the first time, which has been specially sealed to make the 8 and 8 Plus dust and water resistant.

The 12 megapixel cameras on both devices also come with a new photo mode called Portrait Lighting which can be used to add extra lighting to portrait photos.

The iPhone 8 and 8 Plus will also be capable for wireless charging for the first time.

The technology giant said the 8 and 8 Plus are also the first smartphones to have been designed for augmented reality (AR).

The technology mixes real and virtual images on a single screen.

Apple announced a developer kit for the technology earlier this year called ARKit and said this technology has been built into the hardware and software of the new devices.

The tech giant confirmed pre-orders for the two new phones will begin on September 15 and they will go on sale in the UK on September 22.

The iPhone 8 will cost $699, and the iPhone 8 Plus $799.

The company also revealed its latest watch which allows users to make calls, send messages and stream music without a connection to a smartphone.

The Apple Watch Series 3 will launch exclusively with EE on September 22, costing 399 US dollars, the technology giant announced.

The company unveiled its latest gadget at a live event at its new California headquarters on Tuesday.

It is the first Apple Watch to contain its own mobile phone signal in a small electronic SIM, with the screen acting as the antenna.

Apple said the new watch will be able to stream music, as well as take and receive calls directly when the wearer is away from and not connected to a smartphone.

The watch will run Apple’s latest smartwatch software, watchOS4, which can send notifications to users when unexpected raised heart rates are detected.

Another version of the watch without a mobile phone signal will also launch, costing 329 dollars.

The widely rumoured Apple TV 4K was also unveiled, which will support better quality 4K resolution and high dynamic range (HDR) on the streaming box for the first time.

The two technologies are designed to offer a wider range of high quality colours and higher resolution images.

Apple confirmed the new streaming box will also offer 4K content from streaming services including Netflix and Amazon.

It will join the new Apple Watch in going on-sale on September 22.
