cocoa | Ruby FFI bindings for the OSX Cocoa API | Wrapper library

I was working on app that would take some input from the user and put them into a collection view. The data goes to the database and retrieves successfully into a dictionary movies, but while displaying the collection view, it shows doesn't show the third item, but shows the second item twice. After re-running the app, the problem gets fixed. How do I fix this without having to re-run my app every time?

movieCollectionView is my UICollectionView, and MovieCollectionViewCell is my Cocoa Touch Class file for the collection view.

I'm looking into utilizing accessibility APIs provided by macOS and Windows for an application.

The AX stuff for macOS works fine, I can get all the elements of a native Cocoa application.

The Windows APIs is also promising.

However, apps built with frameworks like Electron and such, which incorporate a "web view" are not accessible through the native APIs. They just appear as a black box. This is also the case using the Accessibility Inspector utility for macOS.

I'm not convinced this is a dead end though, because the macOS VoiceOver utility can dig into the web elements and inspect them. Are there separate APIs I need to use to get access to the web elements?

I'm trying to figure out how to use async/await in a Playground using Xcode 12.0 beta / Swift 5.5, but am getting an error every time.

Here's my entire playground code, which is probably wrong:

I'm trying to automate Eclipse installation.

For JDKs for example, I can get the download links via https://api.adoptopenjdk.net/q/swagger-ui/

The Eclipse download button contains a link with a mirror id, and then that page triggers a download. Unfortunately it's not a clean redirect that could be followed with curl/wget. I can observe the final download URL with a proxy like Fiddler, but that is not a stable solution.

I had this working before but now it seems to have stopped. I am trying to run various googlesheets APIS such as read/write/create. I have installed the appropriate cocoa pods:

I can't add a badge to my cocoa App icon on macOs BigSur. I'm trying to update icon's badge in Dock with this code:

I have a macOS app that I wrote years ago; it has been working well on my Mac. Recently I thought it would be nice to have that same app on my iPhone so I added an iOS target to my Xcode project. I have never built for iOS before so I'm on new ground here.

Anyway, when I built for iOS, I got an error message: "Cocoa is not available when building for iOS." In Apple's "Cocoa Fundamentals Guide" there is a prominent statement: "Cocoa is a set of object-oriented frameworks that provides a runtime environment for applications running in OS X and iOS."

Does that mean I can run an app that uses Cocoa but not build one? I'm at a loss; I have no idea how to get past this one. Can an iOS app be built without Cocoa? How would I even go about doing that? Any suggestions at all will be welcome. I'm running Xcode 12.5 on macOS Big Sur 11.4. My app's UI is written in Objective-C and its muscle is in plain C. Also, my app is only for my own use, not for publication.

I've made a test flutter app that uses a plugin I made that simply retrieves the path of the resources folder in my .app and returns it to my dart code.

This works completely fine in the example project generated with the plugin, and has previously worked with my app. I didn't use the plugin for a while after this and it went unused, up until recently as I now had an actual use for it so included it in my code once again. Now the plugin doesn't seem to work with any project I add it to, even freshly made ones.

My plugin consists of this dart code:

How can I write NSAttributedString in rtf file? i found an ancient answer How can I save the attributed string (text) into file (swift, cocoa)? I do not quite understand what exactly is required of me, maybe new different way exists somewhere?
