Unsafe Pointer Errors

[traviskirton]

In Gesture.swift, Packet.swift, and ResonateShapeGenerator.swift, I get the following error:

Cannot invoke initializer for type 'UnsafePointer<UInt32>' with an argument list of type '(UnsafeRawPointer)'

public init(_ packetData: Data) throws {
    var index = 0

    let packetSize = UnsafePointer<UInt32>((packetData as NSData).bytes + index).pointee
    if packetData.count < Int(packetSize) {
        throw PacketInitializationError.notEnoughData
    }
    index += sizeofValue(packetSize)

    guard let t = PacketType(rawValue: UnsafePointer<Int8>((packetData as NSData).bytes + index).pointee) else {
        throw PacketInitializationError.invalidPacketType
    }
    packetType = t
    index += sizeofValue(t)

    id = Int(UnsafePointer<Int32>((packetData as NSData).bytes + index).pointee)
    index += MemoryLayout<Int32>.size

    let dataLength = Int(packetSize) - Packet.basePacketSize
    if dataLength > 0 {
        data = Data(bytes: UnsafePointer<UInt8>((packetData as NSData).bytes + index), count: dataLength)
    }
}

@Aleph7 can you please help me with this error? i'm not clear on how to convert this.
