any 1 can , thank !!

your json response array of dictionaries:

[{"id":"115","exponame":"aziz","expodetails":"aziz","expophone":"aziz","expolocation":"aziz"}]

but you're trying cast dictionary:

let json = try nsjsonserialization.jsonobjectwithdata(data!, options: nsjsonreadingoptions.mutablecontainers) as? nsdictionary 

the solution of course cast array:

let json = try nsjsonserialization.jsonobjectwithdata(data!, options: nsjsonreadingoptions.mutablecontainers) as? nsarray 

better use swift types if can:

let json = try nsjsonserialization.jsonobjectwithdata(data!, options: []) as? [[string:anyobject]] 

then example can use loop:

if let json = try nsjsonserialization.jsonobjectwithdata(data!, options: []) as? [[string:anyobject]] {     item in json {         let usermessage = item["id"] as? string     } }
