Hmm seems like I should just be able to read into the package like a directory, no? And I guess I don't mind too much to waste the extra time allocating the UIImage during the save operation. Could be worse.

Is there a type wildcard for generics? I want to check if a view's concrete class is ModifiedContent<Image, *>. I tried with <Image, Any> as the type constraints but that didn't match when I passed in some Image("something).scaleEffect(number). I'm trying to figure out how tabView is able to tell whether to display the view you pass for the tab buttons even when it's been modified (so it wouldn't be an instance of Image anymore).

Is it possible to set a file's icon from an app? I'm saving user documents, and would like each one's icon to use a screenshot of the doc (that is already part of the document). So, not a single icon, but each file gets its own?

Okay this gets me every time. Why does load(fromContents:type:) call in a UIDocument when you first create the document with save(to:for:completionHandler:)? It's like, you create this blank document, and then a second later it tries to load its contents? edit: hmmm nope maybe there is something going on in my document that's causing this edit 2: double nope, I am confused as hell. I made a blank test document class, and in my app it calls load(fromContents:type:) after save(to:for:completionHandler:). But in a new blank project, the same thing doesn't happen  solution: okay figured it out. If the file already exists at the fileURL, and you call save(to: fileURL for: .forCreating), it will load the contents. But if it's actually a new file, it won't. lord funk fucked around with this message at 17:02 on Jul 19, 2020 |

So it seems that macOS 10.15.6 has a new kernel memory leak in the sandbox extension, as described here https://www.macrumors.com/2020/07/27/vmware-confirms-macos-virtualization-bug-causes-crashes/ . This is really ruining my day/week/month. Any chance someone here knows someone that could escalate this internally for a quick fix? Edit: I downgraded to macOS 10.15.5 because 10.15.6 was unbearable. They don't make it easy to downgrade, good thing I managed to dig up a 10.15.5 installer somehow.

Has anyone used coremltools to generate a model? I'd really like for the resulting bounding boxes to be normalized the same standard way as other VNImageBasedRequest results are, however all that seems to be visible on the Python side is the scaled input image in pixels, nothing about the screen size or the original size of the input image, which would be necessary in order to normalize.

objectWillChange notifying you before it’s changed is the correct behavior. Kinda mystifying why there’s no corresponding objectDidChange, but whatever.

Would’ve been nice if they’d kept didChange, and added willChange for anyone who cares. Having to do it this way is awkward at best...

Spent 2+ hours trying to figure out why my builds started hanging. if you have a class using @dynamicMemberLookup you might be able to reference variable names that don't exist in the code, and instead of failing the build just never finishes. That also broke syntax highlighting in xcode so I wasn't able to spot what the mistake was.

3D people, some advice. I would like to draw 'letterbox' black bars on the top and bottom of my scene. One way I could do this is just do another render pass, and draw the black boxes on top of the already rendered 3D scene. However, I think it would be better to simply stencil out the top and bottom. This would leave it black (yay!) and also skip any rendering underneath (performance!). And, I wouldn't have to load up another render encoder to draw the black bars (performance!). My question is: how do I draw directly on the depth texture / stencil texture? In Metal, they are the same texture (which confuses me... why does the stencil texture show up black in the inspector?). I could blit copy in from another texture, but I'm not really sure how to do that if I also clear the depth texture on load.

They’re “together” because of legacy reasons (Depth24Stencil8 hardware formats), but people use 32-bit float depth buffers now with stencil existing in a separate texture and so it’s just done for convenience. Anyway, the stencil test happens at the rasterization stage, so instead try to use scissor rects or a smaller viewport, so that geometry in those parts of the screen will just get clipped instead (skipping rasterization entirely).

Anyone here have any success shipping a an app that's primarily a webview wrapper to the iOS App Store? I've got a little personal project - a social media web app for sharing songs with your friends and listening back to them through Spotify/Apple Music - that I'd like to make a native app for, but I don't really have the time to make iOS and Android versions of my app from scratch. I would be using several native features: native Spotify/Apple Music SDKs (instead of their JS equivalents), native share target for posting songs, and push notifications. Apple's guidelines for this have been more or less the same for the past few years, from what I can tell: quote:4.2 Minimum Functionality I like to think these new features would, uh, "elevate it" (god they really do use the most vague and obnoxious language for these guidelines huh), but I'm not sure what Apple reviewers would think. So, I'm curious if any of y'all have had any experience with shipping (or trying to ship) a mostly-webview app in the past couple years, and how that's gone. I guess I could build a mostly webview version for iOS and Android, get it out on Android since that's easy, and if it gets rejected by Apple, learn... React Native or some poo poo to build a cross-platform app?

I'm not sure push notifications will be convincing as they're also available to websites. The other bits sound more convincing, but I dunno if it'll satisfy app review. You probably know this already, but you can add a bookmark to your home screen, and you get a bit more control there than you do in a browser. No push notifications though. Fundamentally, the Awful app scrapes a website and dumps it into a webview, but it seems to meet the bar set by app review. There's nothing wrong with using a webview to render 90% of the area of the screen. So what's the difference between Awful and simply pointing a webview at a url? No idea what app review's answer would be, but I bet you could get there without too much pain. One approach might be to pull components out of the webview. No idea what your site looks like, but maybe you pull the navigation menu out and use a proper tab bar controller, with each tab simply loading the relevant webpage (and then hide the navigation bits when you render the webpage). That's probably not enough on its own, so now maybe one of the tabs is a list that you could make into a proper table view. We're probably getting pretty close, and I'd send it off for review to see what happens. Do the same for Android and you've got two apps that are more than just a webview, but hopefully aren't a massive amount of work? And you've got the scaffolding in place if you wanna pull more out of the webview. I assume you can do the above in something like react native too, but I haven't tried.

Does anyone know if Microsoft has quietly dropped the Xamarin cross platform stuff. Got asked to use it for an app that runs on android and ios, but it just isn't in there on Visual studio for mac anymore. Theres references online to installing it from the VS installer, but theres just nothing in there. Its still got the option to do libraries, but the ability to do cross platform apps seems to have been removed :/ Or somethings broken. edit: No, apparently not dropped. Just broken. Goddamn it xamarin Super useful error too: "The project could not be created". In the logs theres a stack trace about a null ref. Doesnt seem to be something I can fix. duck monster fucked around with this message at 07:53 on Sep 8, 2020 |

TheReverend posted:All cross platform sucks, but Flutter is the least sucky imo. I've recently shipped a hobby app with Flutter and while some aspects of it were great, others are still biting me. I'd generally just stick to native iOS but this app relies on a wider community so skipping Android would hurt the iOS users. Granted the problems I've had with it are around the Google Maps component (fundamental to this app) which is still in "developer preview", but it has been for 2+ years. I also found that one of the bugs my users reported after release had been raised on the Github issues (with a one line workaround in the plugin) last September and still hasn't been addressed officially. Aside from quite a lot of missing features, these bugs make it feel like they're not really in a rush to "mature" the framework. Overall it's great for doing quick UI development and hitting both platforms from a single codebase, but a nightmare when bugs crop up and only affect certain devices. Though I feel that's any kind of Android development in a nutshell.
