I’m not doing anything super technical on my phone, so I can’t provide any opinion about things like code writing or testing from it.
I’ve found iOS 17 to be amazing so far on my 15 pro max. My only persistent irk is with the notification management. If a notification pops up that I don’t care to interact with, I’d like the option to swipe it away and have it actually go away. Instead, that initial banner can only be swiped up to make it go to the Notification Center, where it has to be swiped away or opened.
Everything else about the device is phenomenal for me. Battery life (even capped at 80%), 1Password integration, Focus Modes, and Shortcuts.
