Reading plists into a typed Dictionary: Snippet 5

Dictionary+Plist.swift

extension Dictionary {
    init(plistNamed fileName: String, bundle: NSBundle = NSBundle.mainBundle()) {
        guard
            let pList = bundle.pathForResource(fileName, ofType: "plist"),
            let dict = NSDictionary(contentsOfFile: pList)
            else { self = [:]; return }
        
        var result = [Key: Value]()
        dict.forEach { key, value in
            if let key = key as? Key, let value = value as? Value {
                result[key] = value
            }
        }
        self = result
    }
}

//Usage:
let data = Dictionary<String, Int>(plistNamed: "Info")
/* or */
let data: [String: Int] = Dictionary(plistNamed: "Info")
