lazy var session = makeSession()
func makeSession() -> URLSession
let sessionConfig = URLSessionConfiguration.ephemeral
return URLSession( configuration: sessionConfig )
First: is it possible to avoid this one-time function “makeSession” ?
(Assume that makeSession could not be reduced to one line, e.g. add a print() into it)
More important: anybody can set any value to “session”. This is not what I want.
What I really want:
• session should be set exactly once at the first time it is used.
• the compiler should generate an error if somebody tries to set it (like with “let”).
Can this be accomplished? If so, how?
