Apple today released the second beta version of the upcoming watchOS 7.5 update to developers. The new beta version was launched a week after the first beta version was released.
To install the watchOS 7.5 beta, developers need to download the appropriate configuration file from the Apple Developer Center. You can go to General> Software Update through the dedicated Apple Watch application on the iPhone to download the watchOS 7.5 beta. Apple Watch needs to have at least 50% power, must be placed on the charger, and must be within range of the iPhone.
I don’t know what updates watchOS 7.5 brings, and it may include fixes for problems in watchOS 7.4. No new features were found in the first beta version.
