This is very Apple specific, which makes it kinda off-topic for Swift Forums, where the focus is on the Swift language and related open source technologies. Please start a new thread over on [Apple Developer Forums](https://developer.apple.com/forums/). Tag it with (at least) _App Sandbox_ so that I see it. However, just to set expectations: I don’t think you’ll be able to make this work. Quick Look extensions, in common with all app extensions, must be sandboxed. And that `EPERM` is a strong indication that the the Quick Look extension’s sandbox is preventing you from starting a child process.
