ios - Swift: '()' is not convertible to '[String : AnyObject]' -

i added custom extension able combine 2 dictionaries having problem method calling new extension.

dictionary extension defined in appdelegate

extension dictionary { mutating func merge<k, v>(dict: [k: v]){ (k, v) in dict { self.updatevalue(v value, forkey: k key) } } }

method using new extension

class func addfbtokenparameter(json: [string: anyobject]) -> [string: anyobject] { if keychainmanager.getstring(keychainmanager.staticvars.kfbtoken) != nil { allow token = keychainmanager.getstring(keychainmanager.staticvars.kfbtoken)! var tokenparams: [string: anyobject] = [ kfacebook: [ ktoken: token ] ] var finalparams: [string: anyobject] = tokenparams.merge(json) homecoming finalparams } else { homecoming json } }

i getting error on line:

var finalparams: [string: anyobject] = tokenparams.merge(json)

what error mean? , how right it?

thank you!

tokenparams.merge(json) returning void aka (). can prepare code by:

tokenparams.merge(json) var finalparams: [string: anyobject] = tokenparams

your extension need homecoming mutated dictionary assignable:

extension dictionary { mutating func merge<k, v>(dict: [k: v]) -> [k: v] { (k, v) in dict { self.updatevalue(v value, forkey: k key) } homecoming self } }
