Missing bracket??

I have checked this code until I am 'blue in the face', but I can't see why I get an error saying missing closing bracket.

Code Block 
//

import Foundation
class ExploreDataManager {
    func  fetch() {
        for data in loadData() {
        print(data)
    }
}
    fileprivate func loadData() -> [[String: AnyObject]] {
        guard let path = Bundle.main.path(forResource: "ExploreData", ofType: "plist"), let items = NSArray(contentsOfFile: path) else  {
            return [[:]]
        }
        return items as![[String: AnyObject]]
    }
}

If I add an additional bracket it then reports an additional 'Expected '}' in class?
I have counted 5 opening brackets and 5 closing brackets. I even checked to see whether I had mistakenly typed the wrong type of bracket elsewhere in the code!
Is this a bug?
If not what is the reason. for this error?
