ios - Cannot invoke "Append" with Argument list of type '(String)' -


i'm working extensions in swift, , have created extension string follows:

 extension string { func reverse() -> string {     let chars = array(arrayliteral: self).reverse()     var reversed = ""     char in chars     {         reversed.append(char)     }      return reversed } }  name = "faisal syed" name.reverse()

on line says 

reversed.append(char)

i error saying can't invoke "append" argument list of type string.

how work around this?

scala - 'wrong top statement declaration' when using slick in IntelliJ -

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
