Summary:
Xcode should show all the possible variants of using a function with default parameters

Steps to Reproduce:
One attached playground file with code. 
Start typing “doWor” get Xcode code suggestion

Example:
func doWorkWellNil(a: Int, b: Int? = nil) { }

Xcode code completion shows 2 usage suggestion //
doWorkWellNil(a: Int)
doWorkWellNil(a: Int, b: Int?)

func doWork3Params(a: Int, b: Int? = nil, c: Int = 10) { }

Xcode still shows 2 suggestion instead of 4
doWork3Params(a: Int)
doWork3Params(a: Int, b: Int?, c: Int)


Expected Results:

It should show all the possible usage variants
func doWork3Params(a: Int, b: Int? = nil, c: Int = 10) { }

Xcode should show 4 use suggestion: 
doWork3Params(a: Int)
doWork3Params(a: Int, b: Int?)
doWork3Params(a: Int, c: Int)
doWork3Params(a: Int, b: Int?, c: Int)

Actual Results:

Xcode should shows only 2 suggestions: 
doWork3Params(a: Int)
doWork3Params(a: Int, b: Int?, c: Int)
