Can you elaborate a bit more? If I create a passkey on https://passkeys.io on my Mac, then store the passkey in a password manager like Bitwarden, I can log into that site on my phone. I was kinda under the impression that Bitwarden stored the private key on their servers, so if their site gets hacked, then the attacker has access to my passkey.io account?

Don’t remind them, please. 🤪

This Chipotle blog entry describes things the best as far as I know: https://chipolo.net/en/blogs/chipolo-point-delay-and-google-find-my-device-app-update

Basically, in December, Google and Apple (and others?) came up with a standard on discovering trackers that are being used to stalk people. Because of the large iOS install base, Google has elected to wait for Apple to roll out that feature on iPhones before enabling the tracking device support on Android.

There are so many scam apps in the AppStore today. So many apps have slot machine style mechanics that get people addicted and convince them to pay for more turns. In addition, a bunch of kid-friendly apps have really short subscription periods (a day?) At a high price (say $3.99).

It’s not to say that App Review has no value, but when it comes to scams that separate people from their money, Apple has 30% of a reason to look the other way

I mostly have the same experience. I did a Xamarin.Mac app to port some windows code to the Mac. In some senses, it was amazing, because most of the business logic just worked and that saved a bunch of time. The UI was app kit, but with c# to obj-c bindings. That also mostly worked, however, when something broke, it really broke and was incredibly difficult to debug.

There are some use cases I’d recommend Xamarin for still, but the majority of cases are probably best solved by writing native code directly. (Or at least using a portable language such as C, C++ or Rust for cross platform business logic)
