I'm trying to sort out the system/hardward requirements for using Bonjour/NSNetService to connect an iPhone to a Mac.Are these combinations possible:[?] Bluetooth ON, WiFi OFF on Mac and iPhone[?] Bluetooth OFF, WiFi ON on Mac and iPhone, but both devices are not part of any WiFi network (i.e. no router present)[✓ Works] Bluetooth OFF, WiFi On, Mac and iPhone part of the same WiFi networkI got a Bluetooth-only NSNetService up and running between an iPhone and an iPad, but never with a Mac (MacBook Pro mid-2012). Is this a hardware issue or is it not possible to connect an iPhone and a Mac through Bluetooth alone?Thanks!PS: I set includesPeerToPeer = true for the service and browser. My code is based on the WiTap sample code.

Starting with iOS 13 I'm receiving error reports from users that cannot open their iCloud documents anymore. The error is each time: Error Domain=NSCocoaErrorDomain Code=256 "The file “Untitled.txt” couldn’t be opened." UserInfo={NSURL=file:///private/var/mobile/Library/Mobile%20Documents/iCloud~com~myapp/Documents/Untitled.txt}Code 256 means: NSFileReadUnknownErrorRestarting the device solves the problem each time, but I get a lot of error reports. My app does check the availability of iCloud documents (it uses file coordination and UIDocument). This used to work fine before iOS 13.Has anybody seen a similar issue? What could be causing this and how could I collect more useful debug information to get to the bottom of this?

I'm writing a Swift wrapper for Search Kit and ran into a problem. Let's say I have indexed a single document: /documents/hello.txt Now the user moves the document to another folder: /notes/hello.txt How can I update the index after a document was moved without having to re-index the document? There is SKIndexMoveDocument(), but it requires a new parent SKDocument. How would I get a reference to that? I tried creating it via SKDocumentCreateWithURL, but updating the index fails. I assume, because there is no document with the path "/notes/" in the index (it's a folder after all)? The SearchKit Programming Guide says that when moving a document, one should remove the old document from the index and add it again with the new URL. There has to be a better way without having to reindex. Imagine renaming the root folder of a large document tree. Re-indexing all files would be unnecessary if only their URLs changed.
