Is there a way I can set my own app to be the default web browser on macOS? The System Preferences->General UI for choosing the default web browser doesn't have an obvious way to set an arbitrary app. Is there a way to configure my app so that macOS recognizes it as an option for this list?

I'm working my way through adding passkey support to my app. At app launch, I'd like to test to see if the user has already created a passkey for the service, and if not, immediately present the account creation UI. Is there an API call I can make to see if the user already has a credential? From the examples I’ve found, it seems I should just try to sign in, and I’ll get an error callback if there are no stored credentials. Is that right?

Has anyone else run into this and found a workaround? Xcode 13b1, 3, and 4 are unable to prepare my device for development after I updated it today to 14.7.1. Xcode 12.5.1 is able to. After churning for several minutes, it always ends up saying Failed to prepare device for development. I've rebooted the device and my Mac a few times each now. There's at least one other report of this issue: https://stackoverflow.com/questions/68549513/xcode-doesn-t-support-phone-s-ios-14-7-1
