SwiftWebSocket: Swift 2.2 - Unknown attribute asmname

It seems that on Xcode 7.3b2 and the included Swift 2.2 beta version, the keyword @asmname has been removed so all those methods are generating errors and preventing the build.

@asmname("zlibVersion") private func zlibVersion() -> COpaquePointer
@asmname("deflateInit2_") private func deflateInit2(strm : UnsafeMutablePointer<Void>, level : CInt, method : CInt, windowBits : CInt, memLevel : CInt, strategy : CInt, version : COpaquePointer, stream_size : CInt) -> CInt
@asmname("deflateInit_") private func deflateInit(strm : UnsafeMutablePointer<Void>, level : CInt, version : COpaquePointer, stream_size : CInt) -> CInt
@asmname("deflateEnd") private func deflateEnd(strm : UnsafeMutablePointer<Void>) -> CInt
@asmname("deflate") private func deflate(strm : UnsafeMutablePointer<Void>, flush : CInt) -> CInt
@asmname("inflateInit2_") private func inflateInit2(strm : UnsafeMutablePointer<Void>, windowBits : CInt, version : COpaquePointer, stream_size : CInt) -> CInt
@asmname("inflateInit_") private func inflateInit(strm : UnsafeMutablePointer<Void>, version : COpaquePointer, stream_size : CInt) -> CInt
@asmname("inflate") private func inflateG(strm : UnsafeMutablePointer<Void>, flush : CInt) -> CInt
@asmname("inflateEnd") private func inflateEndG(strm : UnsafeMutablePointer<Void>) -> CInt
