According to reports devs have received the option to access the beta for testing purposes, which can be opted into by opening the settings app and selecting the Beta Updates option in the software update section. However, it should be noted that an Apple ID associated with a developer account is required to download and install the beta
This update comes hot on the heels of the 2nd beta, which reportedly caused phones to enter a boot loop when installed. Apple has apparently not decided to update the 2nd beta with a fix for the problem and has instead moved straight on to the third. However, it is still likely that the problem has been fixed.
iOS 17.3 appears to be primarily focused on security, with the introduction of a new security feature called Stolen Device Protection. This feature is designed to keep users' phones safe and make sure that their phones are secure, even if criminals manage to spot the passcode. When the feature is activated, Stolen Device Protection will make it so that certain features on the phone will require Face ID as well as a passcode.
However, iOS 17.3 is not just about security; it is also the version that claims to bring back collaborative playlists at last. Apple removed the functionality, which was initially seen in the iOS 17.2 first beta, because of possible misuse. The ability for Apple Music users to collaboratively edit, add, reorder, or remove songs from a shared playlist was brought back in the first beta version of iOS 17.3.
