Not sure on exactly how you are wanting to use this but you could approach this
like:
let bytes: [UInt8] = [ 0xC0, 0xC0, 0xA1, 0x00, 0xC0, 0xC0, 0xA1, 0x00]
let slice = bytes[0..<4]
slice.withUnsafeBytes { buffer in
let d = Data(bytesNoCopy: UnsafeMutableRawPointer(mutating:
buffer.baseAddress!), count: buffer.count, deallocator: .none)
// whatever you do, dont let d escape
}
