Problems with NSWorkspace openURL: Handling File URLs on macOS 13.6
I'm learning this framework and I'm not sure how to approach I've looked through the documentation and I'm still confused about I've been struggling with this for a few days now and could really use some help... Quick question that's been bugging me - I'm working on a macOS application where I need to open specific file types using `NSWorkspace`'s `openURL:` method, but I'm working with issues when trying to open certain file URLs. For example, when I attempt to open a PDF file located in the user's Documents folder, the application crashes with the behavior `Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'The URL provided is not a valid file URL.'`. My code looks like this: ```swift let fileURL = URL(fileURLWithPath: "/Users/username/Documents/sample.pdf") NSWorkspace.shared.open(fileURL) ``` I've confirmed that the file exists at that path by checking the file system and I added a print statement before the `open` call, which outputs `fileURL: file:///Users/username/Documents/sample.pdf`. Despite this, the behavior continues. I've also tried wrapping the `openURL:` call in a `do-catch` block to catch any potential exceptions, but I need to seem to get any additional information out of it. I've read on forums that sometimes issues arise when the URL is not properly formatted or if the application doesn't have the necessary permissions to access the file. I checked the app's entitlements and made sure it includes the necessary file access permissions. Is there a specific requirement I'm missing for opening file URLs with `NSWorkspace` in macOS 13.6, or is there a better approach to handle opening files directly from my app? Any tips or insights would be greatly appreciated! Any ideas what could be causing this? This is part of a larger service I'm building. Any help would be greatly appreciated! This is for a mobile app running on Linux. I'd love to hear your thoughts on this. The project is a REST API built with Swift. What are your experiences with this? Any ideas what could be causing this?
