Where to put reusable functions in IOS Swift? -

new ios programming wondering best place put functions use throughout code. example, want write few functions perform post request web service , return dictionary. maybe function calculations. best create .swift file , put functions there. , name give file if so?

public func postrequest() -> [string:string] {      // post request , return post data      return ["somedata" : "somedata"] } 

the best way create helper class static functions, this:

class helper{     static func postrequest() -> [string:string] {          // post request , return post data          return ["somedata" : "somedata"]     } } 

now every time need use postrequest can use so: helper.postrequest()

i hope helps you!
