Hi, the following query  
`urlComponents.query = "media=music&entity=songs&term=\(searchTerm)"`

returns response with status 400 with following body:

> {  
> “errorMessage”: “Invalid value(s) for key(s): [resultEntity]”,  
> “queryParameters”: {  
> “output”: “json”,  
> “callback”: “A javascript function to handle your search results”,  
> “country”: “ISO-2A country code”,  
> “limit”: “The number of search results to return”,  
> “term”: “A search string”,  
> “lang”: “ISO-2A language code”  
> }  
> }

I changed the query to  
`urlComponents.query = "term=\(searchTerm)"`  
and I got the response status 200 with app showing the results. Please update for posterity. Thanks. Very useful tutorial though. 🙂
