How to convert Any to Int in swift?

Before asking this question I have searched the Stackoverflow’s related questions, and found a similar one: How to convert Any to Int in Swift.

My requirement is not that less:

let tResult = result as? [String:AnyObject]
let stateCode = tResult?["result"] as? Int

My need is if the tResult?["result"] is a String class, I want it to be convert to Int too, rather than to nil.

In objective-c, I wrote a class method to get the 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 it possible to write a similar class method using Swift3?
