Excellent question! Swift’s overload resolution has some built-in preferences for picking static methods when referencing based on a metatype and for picking instance methods when referencing based on an instance, e.g.,

class X {
  static func f0() -> Int { return 0 }
  func f0() -> String { return "" }

let fn1 = X.f0 // () -> Int
let x = X()
let fn2 = x.f0 // () -> String

So one might have to conjure up an instance to force the instance method, or use type context to force the issue:

let fn3: (X) -> () -> String = X.f0

but it can be done without extra syntax.
