Yes, I see that it works, but it is built totally different from what it says in the documentation. Is there or will there be any other document where I can see a tutorial on how to use FxPlug? The truth is, the project that creates the template is extremely different and totally different from the references that the documentation makes. @DarrinC

It seems that the delegate suggests it in their Apple instructions, and it's even pre-built when adding an XPC service using the Xcode template. However, the guidance from Apple appears somewhat vague, lacking specific instructions on utilizing FxPlug and setting up the template in Xcode. Despite downloading Final Cut Pro during its trial period, there's no clear indication within the app on creating any template in Xcode. Motion lacks a trial period altogether. I've diligently followed Apple's instructions step by step, yet I'm puzzled as to why it's not functioning as expected. I'll include some contents of the pluginkit package for further context. @DarrinC

Any suggestions @eskimo @DarrinC ?

Ok, This is all that appears when I see the content, but when I run the app and check the console I get this error. and yes in my main I call [FxPrincipal startServicePrincipal]; @DarrinC

I am facing a challenge when trying to create a filter for images using FxPlug, with the intention of later integrating it into Motion or Final Cut Pro. The problem arises when the connection to the XPC service I am using is lost. When configuring the FxPlug SDK in Xcode and building the application, it appears that the XPC service is no longer available. This disconnection prevents my application from correctly interacting with the XPC service required for the image filter. I would appreciate any guidance or suggestions on how to fix this issue and restore the connection to the XPC service so that my application can work as intended @DarrinC @eskimo

Well I see that the problem only occurs when I add FxPlug SDK, I can create another new project and add an XPC service and absolutely nothing happens, in fact it responds very well and everything works, only when following the documentation https:// developer.apple.com/documentation/professional_video_applications/fxplug/building_an_fxplug_plug-in_manually?language=objc, the project gets corrupted and can no longer connect to my XPC service. @eskimo

Now I got this new Error error description -> Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.FxPlugTestXPC was invalidated: failed at lookup with error 3 - No such process." UserInfo={NSDebugDescription=The connection to service named com.FxPlugTestXPC was invalidated: failed at lookup with error 3 - No such process.} , error user info -> { NSDebugDescription = "The connection to service named com.FxPlugTestXPC was invalidated: failed at lookup with error 3 - No such process."; } and error localizedDescription -> Couldn’t communicate with a helper application. @eskimo

I literally have the same problem, I already did what Eskimo recommended and I have the same problem, it always tells me that the sandbox restricted something or that the connection simply cannot be made with the XPC service that I have!

Same here , Has this issue been resolved?

yes , I already try that and delete the derived data and the error continue.
