I use WCSession sendMessageData to transfer images across from my iPhone to my watch. Everything works fine if the images are smaller. When they get bigger the messaging fails with

Message reply failed.

I assume there is a maximum size for data sent with sendMessageData and it should be around ~70kb but I can´t find any piece of documentation on this. Can anybody help me out and maybe tell me if I can influence the maximum size of the data?

Thanks in advance!

    The transferFile API seems like a much better fit for this, and transfers the contents just as fast as messages from my experience – ccjensen Dec 04 '15 at 20:54
  • I totally agree that transferFile is way better for transferring files like images. The disadvantage of transferFile though is that I can not precisely set the moment when the file is transferred. I wanted to use sendMessageData to request an image immediately. – Philipp Otto Dec 07 '15 at 15:26
