Recently, Apple officially pushed watchOS 4.2 to the Apple Watch, fixed some bugs, and added a very practical function that we can't use: Apple Pay Transfer.

Apple Pay transfer is also an important function in iOS 11.2, but unfortunately, it cannot be used in China（ WeChat Alipay ）。 Before using the transfer function on the Apple Watch, users must go to the settings of the iPhone or iPad to enable it.

In addition to supporting transfer, there are the following changes in watchOS 4.2:

• Added support for HomeKit water dryer and faucet, which can be controlled by watch
  

• A new fitness method has been added, enabling third-party apps to track distance, average speed, running times, and statistics of altitude decline when skiing with Apple Watch

• Fixed a bug that caused the watch to restart when Siri asked about the weather

You can now upgrade your Apple Watch to the latest system. Go now.
