Mastodon

isaiahsometimes simple code is best. i really like this category method on NSFileManager:``` - (BOOL)linkOrCopyItemAtURL:(nonnull NSURL *)srcURL toURL:(nonnull NSURL *)dstURL error:(NSError *__autoreleasing _Nullable * _Nullable)error { BOOL success = [self linkItemAtURL:srcURL toURL:dstURL error:error]; return (success) ?: [self copyItemAtURL:srcURL toURL:dstURL error:error];}```<a href="https://mastodon.social/tags/obj" class="mention hashtag" rel="nofollow noopener" target="_blank">#obj</a>-C <a href="https://mastodon.social/tags/AppKit" class="mention hashtag" rel="nofollow noopener" target="_blank">#AppKit</a>

Uli Kusterer (Not a kitteh)DST change reminded me of that time QA discovered that, if you build a date from NSDateComponents, any missing items will not be set to zero, but will be set to the corresponding value from the current date and time.Which meant that my March 30th, 12:00 would get random one-minute-drift like 12:00:59 because the user entered the date right before a minute change.Makes sense for the date, but was a bit bewildering for the time, especially seconds.<a href="https://chaos.social/tags/cocoa" class="mention hashtag" rel="nofollow noopener" target="_blank">#cocoa</a> <a href="https://chaos.social/tags/appkit" class="mention hashtag" rel="nofollow noopener" target="_blank">#appkit</a> <a href="https://chaos.social/tags/foundation" class="mention hashtag" rel="nofollow noopener" target="_blank">#foundation</a> <a href="https://chaos.social/tags/macProgramming" class="mention hashtag" rel="nofollow noopener" target="_blank">#macProgramming</a>

Pasi SaleniusIt’s kind of strange that if you have several NSToolbars in your app and the user customizes the display mode in one of them to, say, “Icon and Text” this state does not sync to all of the app’s toolbars. There also doesn’t seem to be any obvious way to observe changes to these settings. I guess that’s just okay and the user is expected to customize them all separately..?Or I wait until next WWDC and our Mac windows won’t have toolbars anymore as they have been designed for “the next generation of users”.<a href="https://infosec.exchange/tags/appkit" class="mention hashtag" rel="nofollow noopener" target="_blank">#appkit</a>

Mario GuzmánCultured Code's Things app used to be one of those shining examples, good-Mac-citizen apps. The UI and UX was just *chef’s kiss*. The icons and design would make you think 2010 Apple designed it. I miss when we had a good visual distinction between user content and UI belonging to the app. Not all types of content needs to "blend" with your app's UI.
