I'm developing a Mac application that monitors a piece of state on your computer and communicates it to a nearby iOS device. Both are using CoreBluetooth to communicate. You can think of the iOS device as a "status sign" for your Mac. I started out by making the Mac the "central" and the iOS device the "peripheral". The Mac tries to keep a persistent BL connection to the iOS device to write a value whenever the state changes. However, I find that the the iOS device often disconnects. I can also see an implementation where the iOS app is the central and subscribes to a characteristic of the Mac peripheral. Here's my question - for those of you with more Core Bluetooth experience, based on my use case, which should be the central and which should be the peripheral?

In macOS Big Sur, is there a way to remove the rounded corners from the iOS Simulator windows? I'm not looking to change this setting system-wide, just for the simulator. Why? For older simulators like iPhone 8 and older iPads, the rounded corners in the non-bezel windows clip part of what the end user would see. It's small, but it matters in my use case.
