Update to @MartinR's answer… a Swift 3 extension to provide a string for sorting / searching, that might be useful for someone…

extension String {
    var forSorting: String {
        let simple = folding(options: [.diacriticInsensitive, .widthInsensitive, .caseInsensitive], locale: nil)
        let nonAlphaNumeric = CharacterSet.alphanumerics.inverted
        return simple.components(separatedBy: nonAlphaNumeric).joined(separator: "")
    }
}

e.g.

print("Mÿ nâMe ís jÄço´B".forSorting) // "mynameisjacob"
