This is the error I am continuosly receiving.

@discardableResult func doSomething() -> Bool { // does something return true } This function can be called in the following ways: doSomething() let didSucceed = doSomething() Is there a way to differentiate the two from inside the doSomething() function, as in, is there a way to know if the caller is using the result?

I want to build a Swift library package that uses modified build of OpenSSL and Curl. I have already statically compiled both and verified I can use them in an Objective-C framework on my target platform (iOS & iOS Simulator). I'm using XCFramework files that contain the static library binaries and headers: openssl.xcframework/ ios-arm64/ openssl.framework/ Headers/ [...] openssl ios-arm64_x86_64-simulator/ openssl.framework/ Headers/ [...] openssl Info.plist I'm not sure how I'm supposed to set up my Swift package to import these libraries. I can use .systemLibrary but that seems to use the embedded copies of libssl and libcurl on my system, and I can't figure out how to use the path: parameter to that. I also tried using a .binaryTarget pointing to the XCFramework files, but that didn't seem to work as there is no module generated and I'm not sure how to make one myself. At a basic high level, this is what I'm trying to accomplish: where libcrypto & libssl come from the provided openssl.xcframework file, and libcurl from curl.xcframework

HI, I have a app with Swift Programming language. It is built successfully on my Monterey Intel by using Xcode 14. I am trying to built same app on Sonoma Silicon arm64 by using Xcode 15.4.

I'm currently syncing core data with the CloudKit private and public databases, as you can see in the code below, I'm saving the private database in the default configuration in Core Data and the public in a configuration called Public everything works fine when NSPersistentCloudKitContainer syncs, what I'm having an issue with is trying to save to the public data store PublicStore, for instance when I try to save with func createIconImage(imageName: String) it saves the image to the "default" store, not the PublicStore(Public configuration).

As the topic mentioned, I want to add a overlay window onto Apps that are in full screen mode, trying to create some blur effect on the screen. But Apple seems to treat full screen mode Apps differently as a "space." So currently I can only apply the blur effect like this. (This is my Desktop page) But When it doesn't affect the full screen mode Apps. (For example: My Xcode) And I know some of the App down this kind of stuff. Like this This is my current code. Hope someone can tell me how to solve it.

Hi, I am developing an app that has a WKWebView and it can open sites like Youtube. The app is sandboxed as it is meant to be uploaded to the mac App Store. It has a feature PiP where we start the native PiP by calling a browser Javascript where we tell the WKWEBView to fire the PiP. It works well when we are running the code from XCODE in Debug scheme. When we run the code from release mode by archiving it or directly from the build folder, the WKWebView is not able to fire the PiP Agent and thus the Native PiP window is not visible, while the site shows that PiP is opened and we can here the sound being played. But PiP window is not visible. I cannot see PiPAgent in activity monitor. Why does it not work from within the release build outside xcode. But when I try to run the build directly from the Finder in builds folder, this PiP feature does not work. Request technical help for this. Thanks!

I'm continuing with the migration towards Swift 6. Within one of our libraries, I want to check whether a parameter object: Any? confirms to Sendable. I tried the most obvious one: if let sendable = object as? Sendable { } But that results into the compiler error "Marker protocol 'Sendable' cannot be used in a conditional cast". Is there an other way to do this?

Hey, im new here. And I need to share a variable between files, settings and home. I've searched all over and found solutions, but I just don't understand what to do.

Hello there, we have the following crash in production (99% in background) with our latest release, but we are not able to indentify 100% the main actor. It could be Intercom SDK. Firebase reports: Crash CoreFoundation __CFRunLoopServiceMachPort mach_msg __CFRunLoopServiceMachPort Any suggestion?

Hi, I am writing my own little toy programming language and when I try to link the binary object file (.o file) it requires a _main symbol. I wonder if there is a way to exclude this, presumably, a C runtime requirement? Is it safe to provide a stub _main symbol, or provide a the _main as the entry point to my own little runtime? What is the correct way to invoke the linker with the appropriate flags?

I'm working on creating a tiny app that copies a random sampling of files from a source folder to a destination folder: https://github.com/belovachap/Select-Random-Files-Mac I choose folders in my user's Documents folder, am able to get the random sampling of files but then run into permission errors when trying to copy to the destination folder. I've tried adding a call to startAccessingSecurityScopedResource on the destination URL but it doesn't seem to help. Is this having the same problems on anyone else's computer??

Anyone can help ?

I created a content filter app in iOS (swift). The app lets me toggle the content filter ON or OFF. When the content filter is on, it restricts access to one particular url. This works as intended; however, I would like to generate a log that shows the url from each inspected flow (I'm using NEFilterFlow to inspect the url from each webkit flow). Ideally, I'd like the url, the verdict, and the verdict timestamp appended to the log each time a flow passes through the content filter for a decision. I cannot figure out how to capture any data from the flow. I'm even trying to use the NEFilterReport class, but I can't seem to capture any of the data in the report. Can the url even be extracted from a NEFilterReport? I assume it can, since it's part of the flow. I understand that FilterDataProvider can only communicate with FilterControlProvider (on a very limited basis). However, it is my understanding that FilterControlProvider can communicate with the main target. So how can I send the url from FilterDataProvider over to FilterControlProvider, and then onward to the main target to print to the console? I'm starting to read about IPCConnection. Hopefully that is the answer to my question and I will get there in the coming days. If not, please help. There is very limited information out there on the network extension framework and content filtering.
