"Expected expression in Swift key path" Error while Refactoring code with Extensions

I have been trying refactor code by thanking functions and adding them in a separate file extension of a ViewController

What I have in this extension is a function that adds gesture recognizers to some views that have references to functions that I have placed in other file extension of the same ViewController. On build I am getting this error "Expected expression in Swift key path"

What is causing this error?

Solution

  • I got this error when I accidentally left a backslash after a bracket in my object init: 

    init(for note: Note, atAnchor anchor: ARAnchor) {\

    let billboardNode = note.type.basicNode

    self.node = billboardNode
    self.text = note.description ?? "[No Text]"
    self.type = note.type
    addText()
}

    Removing the backslash fixed the error. Check out this answer by user eharo2 for details about why!
