Running terminal commands from Cocoa App in Swift failing: "command not found" but works using Command Line Tool in swift

I created an App that exports all of my iMessages into an app I use for journaling. It accesses the chat.db file in Libary/Messages/ to do this. This part works great

I was required to use frameworks and Command Line Tools won't allow you to bundle Frameworks in macOS. I would have preferred to for this all to be a script and avoid Cocoa altogether, but was required to use a full Cocoa application because of the need for bundled Frameworks

I can enter commands like pwd and get a response back. However, when I try to run the terminal commands for the journaling app, it fails with "command not found"

If I run the exact same command from within terminal, or from within a Swift Command Line Tool in Xcode, it works. However, now that I'm using an actual Cocoa app it won't work.

Here is an example of my code:

   let pipe = Pipe()
let task = Process()
task.launchPath = "/bin/sh"
task.arguments = ["-c", String(format:"%@", "dayone2 new 'Hello'")]
task.standardOutput = pipe
let file = pipe.fileHandleForReading
task.launch()
if let result = NSString(data: file.readDataToEndOfFile(), encoding: String.Encoding.utf8.rawValue) {
    return result as String
}
else {
    return "--- Error running command - Unable to initialize string from file data ---"
}

and the response: /bin/sh: dayone2: command not found
