Not sure why Swift is giving me a "Cannot find 'xFile' in scope" error

I have the following structure :

struct XFile : Codable {
   ...variables here   
    
    init(fileUrl: URL, key: String) {
    ...
}

Then in another class I am trying the following:

class UploadTask {
	var xfile: XFile
	var inProgress = false
	
	init(file: URL) {
		xFile = XFile(fileUrl: file, key: "filename")
	}
}

If typed as above Xcode gives me the following error:

Cannot find 'xFile' in scope

If I remove the xFile= part,

Xcode give me the following warning and error:

Result of 'XFile' initializer is unused
Return from initializer without initializing all stored properties

Obviously I am breaking some rule, just not sure what it is.
