Swift 2.0 gist to quickly determine if a String contains an uppercase alphabetical character

UpperCaseLetter.swift

extension String {
    func containsUpperCaseLetter() -> Bool {
        let beginCodePoint = Character("A").unicodeScalarCodePoint()
        let endCodePoint = Character("Z").unicodeScalarCodePoint()

        for scalar in self.unicodeScalars {
            if case beginCodePoint...endCodePoint = scalar.value  {
                return true
            }
        }

        return false
    }
}

extension Character {
    func unicodeScalarCodePoint() -> UInt32 {
        let characterString = String(self)
        let scalars = characterString.unicodeScalars

        return scalars[scalars.startIndex].value
    }
}
