Hi qHolmes.
you are having some odd issues with ios publishing. touch info ought to work for example. Have you checked the samples provided by Unity like the penelope project and similar? this is your first stop to have fun with IOS.
Or are you saying touch info doesn't work within playmaker?
Unity remote: the rendering quality on the device is bad because it's only a stream from Unity own game view. you can switch it off since anyway, unity remote is only there to allow to get touch infos, at which i'ts not 100% accurate nor reliable, so really unity remote is only here to validate the basics, publishing on the device is mandatory for any major feature added regards touch handling, new models textures, material works etc, to watch for perfs, framerate, memory warning, similar things impossible to witness on your mac.
Bye,
Jean
