ios - array created with optional -


i declaring array:

var array:[string] = []

assigning values:

array.append(uniqueid string)

and pass function:

static var levels_array : [string] = [] class func setlevelsarray(arr:[string]) {     gameprefrences.levels_array = arr     println(gameprefrences.levels_array) }

my problem when print array get:

[optional(88868658), optional(112051080), optional(95274974)]

why optional? want strings in array why "optional" added?

i come java can explain why optional created , how remove it

very actual strings "optional(88868658)", etc. have created strings optional accidentally. in above code, have array of strings, not array of optionals, , when print array of strings, don't include double-quotes (which can confusing).

it may happening here:

array.append(uniqueid string)

what type uniqueid? as not used convert types. it's used cast them if possible (though should fail if that's case; i'm suspecting you're doing string interpolation somewhere).
