SwiftySurrogate

Usage

Use UTF16 surrogate easier in Swift.

    var emoji1 = SwiftySurrogate.decodeFromSurrogatePair(surrogatePair: "D83D:DCC9")
    var emoji2 = SwiftySurrogate.decodeFromSurrogatePair(high: 0xD83C, low: 0xDF80)

You can convert between surrogate pair to unicode scalar.

    expect("D83D:DE04") == "\(SwiftySurrogate.convUnicodeScalarToSurrogatePair(0x1F604).0!.hexExpression()):\(SwiftySurrogate.convUnicodeScalarToSurrogatePair(0x1F604).1!.hexExpression())"
    // true

    expect(UInt32(0x1F604)) == SwiftySurrogate.convSurrogateToUnicodeScalar("D83D:DE04")
    // true

Catch decoding error by optional check.

    // This will fail
    if let res = SwiftySurrogate.decodeFromSurrogatePair(surrogatePair: "FFFF:DE04") {

    } else {
        // Get the error
        println(SwiftySurrogate.lastError())
        // print -> Optional(Error Domain=SwiftySurrogateErrorDomain Code=504 "High Surrogates (FFFF) must be less than 0xDBFF" 
    }
