Hi. I also want to add that im thoroughly enjoying the older macos tutorials. I said in a previous post that for me at this, this is the reason for being for your site, its your claim to fame and what put you on the radar
I just completed the drag and drop tutorial by warren burton, one of your better tutorial writers imo. What i’ve been doing is translating both the sample projects and the tutorial code to objective-c as part of the learning experience. Warrens sample code is also top quality compared to other tutorials.
Since i can’t make new posts, and the discussion for that thread has been closed, in case you’re interested there seems to be a small problem with the logic in the final stages of that tutorial. When reading the pasteboard types on high sierra at least, it seems that the entire history of the pasteboard is made available, not just relative to that app running, so simply looking for the presence of the TIFF type or the custom sparkle type wasn’t enough. The first check always returns true because what im guessing is the prior pasteboard use. Im not sure if this is the most elegant solution, but i got it working by using dragginginfo.draggingsource iskindofclass instead of pasteboard.types.
Also the translation of that project to objective-c experience completely cemented how horrific swift is as a language compared to objective-c, and im truly mortified apple are promoting this language as easier to learn. Inferred types is nasty business, but why swift is terrible you could write books on.
Anyway. The real other point of this post is i absolutely love your macos tutorials, as stale as they are, and if you don’t know already… you are the ONLY SOURCE of these online Best of luck.
