run in viewDidload, this is my code :

The data is being fetched asynchronously and the print statement is getting executed before the response is received. print the data after you assign value to self.jumlahStok

I have a string with brackets in it from which have to remove/strip the substring.
For ex:
"8383838383(1234)" //string value
"8383838383" // desired result.
Thanks in advance
"8383838383(1234)".substringToIndex(string.rangeOfString("(")!.startIndex)
// "8383838383"
Building on #Tim's suggestion -
let strFull = "8383838383(1234)"
var str = strFull.substringToIndex(strFull.rangeOfString("(")!.startIndex)

How to write something
if !inBoundary then do
printfn "no it's not within the boundary"
You can use the not built-in function (and omit the do keyword after then):
let inBoundary = false
if not inBoundary then
printfn "no it's not within the boundary"

I have a string from user input that is in the following format:
"foo\U+FFE2\U+FFB5\U+FFE2\U+FFB5"
When I view this it does not show anything in the browser or terminal, but they are definitely there.
What are they and how do I remove all junk chars like these to end up with just 'foo'?
I know I could just remove these specific ones but there maybe other different ones that I want just the text value from.
Any ideas?
I see the two main variants:
with #split/#join pair:
"fooффф".split('').select{|x|x.ord <= 127}.join
# => "foo"
with #unpack/#pack pair:
"fooффф".unpack('U*').select{|x| x <= 127}.pack('U*')
# => "foo"
