SwiftUI doesn’t offer anything equivalent to NSFilePromiseProvider, i.e. to write data to the drop destination. You have to ditch SwiftUI and use AppKit’s drag & drop APIs instead. FB13583826. Is that it? I know that’s not a very helpful in some sense, but I wasted days trying to figure out how to implement this very… Read more
Perhaps in karmic balance of my previous post critical of one of Apple’s APIs, I want to highlight an Apple OS feature that I use every day, that ironically is so simple, obvious, and reliable that I almost never stop to appreciate it. Universal Clipboard basically just means you can copy something on one device… Read more
I find FileManager‘s url(for:in:appropriateFor:create:) to be very unintuitive. It seems to have multiple, largely-orthogonal functions. It can provide paths to common folders (albeit badly). It can create temporary folders. It can locate volume-specific bins (Trash folders). It is an example of bad API design. Specifically, regarding cohesion: the principle that an API should have one… Read more
Creating a file is a pretty basic and conceptually simple task, that many applications do (whether they realise it or not – library code often does this too, at least for temporary files such as caches or for communicating between programs). So you’d think it’d be trivial to do correctly. Alas, it is not. ☝️… Read more
I sometimes forget that this is possible (and even more often exactly what the damn syntax is – kudos to vacawama in today’s case of this for reminding me with their StackOverflow answer). There are numerous other ways to write the above, but I think it is the most elegant. Inferior Alternatives More indentation, and… Read more
This is an elaboration of a post I made in a Swift Forums thread, SE-0419: Swift Backtracing API. The question was raised whether an official Swift backtracer should try to support code that doesn’t use frame pointers. Which immediately raised the question – in my mind – of if anyone is still using the “optimisation”… Read more
I’ve been getting this notification every morning, on both my Macs, for several days now. System Settings says Private Relay is active like normal, even so. Yet Mail refuses to load any images in emails. Yet Safari works fine. So it’s not at all apparent if Private Relay actually is working or not. Sometime during… Read more
