ios - How to convert Any to Int in swift? -


before asking question have searched stackoverflow's related questions, , found similar one: how convert int in swift.

my requirement not less:

let tresult = result as? [string:anyobject] let statecode = tresult?["result"] as? int

my need if tresult?["result"] string class, want convert int too, rather nil.

in objective-c, wrote class method converted int:

+ (nsinteger)getintegerfromidvalue:(id)value {     nsstring *strvalue;     nsinteger ret = 0;     if(value != nil){         strvalue = [nsstring stringwithformat:@"%@", value];         if(![strvalue isequaltostring:@""] && ![strvalue isequaltostring:@"null"]){             ret = [strvalue intvalue];         }     }     return ret; }

is possible write similar class method using swift3?

less verbose answer:

let key = "result" let statecode = tresult?[key] as? int ?? int(tresult?[key] as? string ?? "")

results:

let tresult: [string: any]? = ["result": 123] // statecode: 123 let tresult: [string: any]? = ["result": "123"] // statecode: 123 let tresult: [string: any]? = ["result": "abc"] // statecode: nil
