  1. I am doing the resizing Icons from the uifx files that i downloaded and they are not all 125×125. So I am getting a error: Not a valid resample value after doing the sips -z *.png

    • Not sure about that error. I will have to look into it further (busy at ISE right now).

      But you do not need to resize the UIFX icons. The different sizes are already provided.

      The video showing you how to resize graphics is there in case you need to resize your own graphics.

  2. I am getting this warning on this line of code. Can you help me?
    ‘characters’ is deprecated: Please use String or Substring directly

    if output.write(writeString, maxLength: writeString.characters.count) < 0

    Thanks,
    Rick
