swift - How do I correctly print a struct? -


i'm trying store array of store structs within users struct, can't print correctly.

struct users {     var name: string = ""     var stores: [store] }  struct store {     var name: string = ""     var clothingsizes = [string : string]()         }  var myfirststore = store(name: "h&m", clothingsizes: ["shorts" : "small"]) var mysecondstore = store(name: "d&g", clothingsizes: ["blouse" : "medium"])  var me = users(name: "me", stores: [myfirststore, mysecondstore]) println(me.stores)

you’re initializing them fine. problem store struct using default printing, ugly mangled version of struct name.

if make conform customstringconvertible, should print out nicely:

// swift 1.2, use printable rather customstringconvertible  extension store: customstringconvertible {     var description: string {         // create , return string how         // you’d store when printed         return name     } }  let me = users(name: "me", stores: [myfirststore, mysecondstore]) println(me.stores)  // prints "[h&m, d&g]"

if printing code quite complex, it’s nicer implement streamable instead:

extension store: streamable {     func writeto<target : outputstreamtype>(inout target: target) {         print(name, &target)     } }

p.s. convention have types structs start capital letter
