My GeoShred does not have a Sylphyo input. Maybe you are mixing it up with the SWAM MIDI setting?
Sylphyo is a pure MIDI controller. The GeoSWAM input requires a MPE controller. MPE is a complex superset of MIDI.

If you are interested, the difference (greatly simplified) is as follows: In pure MIDI note and control data are sent on the same channel. In MPE most control commands are sent on channel 1, whereas note data and some control commands (such as Aftertouch) are sent on channels 2 to 16.

Hence, in order to play GeoSWAM using the Sylphyo you will, at a minimum, need to use the settings that I described earlier: "Sylphyo breath control to Aftertouch, Sylphyo MIDI channel to 2, Sylphyo base note at C4 and the GeoShred MIDI to SWAM."

@reidid789 unfortunately you can only get the SWAM on iOS via GeoShred Pro. Audio Modeling have promised a stand alone iOS SWAM early next year if you have the patience to wait.

I picked up GeoShred Play for free a while back and then upgraded to Pro which was cheaper than buying the Pro version outright. I think that GeoShred Play may be free again for Black Friday.

@reidid789 I connect the mini jack output to a Roland Mobile Cube and I am very happy with the quality of the sound.

The Roland has a surprisingly good sound when you consider its size. I like the iPhone/Roland combination since it allows me to be as mobile as possible.

Please disregard my previous post, GeoFlute with Sylphyo does work! :-)

If you want to know how and are not interested in my continuing ramble, please go to the end.

I was determined to get GeoFlute working.

So since I already have Audiobus on my iPhone, I bought a MIDI converter, mfxConvert, with the aim of converting Aftertouch to Channel Pressure.
Activating the converter in learning mode, I discovered that the Aftertouch of the Sylphyo is really sending MPE Channel Pressure all along!
So what gives?

In the end the problem was really simple. GeoFlute only starts from C4 and covers 3 octaves. So simple that it initially didn't occur to me. I had been spoiled by the 5+ octaves of the Sylphyo. :-)

Once I started playing above C4, the result was spectacular. It is the closest sound I have gotten with my Sylphyo to my real flute up to now. I am amazed that a iPhone 6S can generate such a realistic sound. I still have to learn how to control the sound better but I am very optimistic.

I am not sure if some of the other CCs from the Sylpho will need to be remapped from channel 2 to channel 1 to conform to the MPE spec but I have mfxConvert if I need to.
Maybe @Support_AODYO can add a MPE output option in the future and save all this hassle?

So, in short, to start playing GeoFlute with Sylphyo, set Sylphyo breath control to Aftertouch, Sylphyo MIDI channel to 2, Sylphyo base note at C4 and the GeoShred MIDI to SWAM. I also recommend that the Echo and Reverb of the GeoFlute be turned off, at least at first.

I bit the bullet and bought the GeoSWAM Flute.
The short answer is no (or not yet - see below). :-(
The long answer:
Before buying the GeoFlute I read the warning that it requires a MPE so I first tried experimenting with the GeoShred Pro using its MPE Midi input setting. By setting the Sylphyo to channel 2 and setting breath to CC7 I was able to play the GeoShred.

So far so good.

I also read that MPE uses Channel Pressure as Aftertouch. Sylphyo has Aftertouch but no Channel Pressure. However, I noticed that Respiro has a MPE-Aftertouch option for breath control. When I set Respiro to this and tried with Sylphyo set to Aftertouch for breath control it worked!
So was the Respiro MPE option mislabelled or was MPE using Aftertouch after all?
The only way to check was to buy GeoFlute and try. Which I did and you know the answer already. it doesn't. :-(

Some good news, if I use Sylphyo Inertial mode on Midi channel 2, the GeoFlute plays. This is because the MPE spec has global CC commands on channel 1 and note and expression commands on channels 2-16.
Hence I have the hope that if the fine folk at Aodyo were to add Channel Pressure to the list of breath control options, then it will be possible to play the GeoFlute with Sylphyo using channel 2. How about it @Support_AODYO ?

I have a Mac with USB-C. I did not have any problem updating.
I used the genuine Apple USB to USB-C adapter.

I made some plugs from old wine bottle corks by cutting them into "V" shape that becomes narrower along the length.
This way, I can control the pressure by how much I push the plug in or out.
These also let moisture escape.

I agree with @randybrown that it is too easy to fall down the rabbit hole. :-)

I bought my Sylphyo before the upgrade was available and invested hours looking for the "perfect" flute sound for my iPhone.

I ended up using BS-16i on my iPhone. It is definitely an excellent lightweight solution. It works out of the box with the Sylphyo, is easy to use and has very low latency. Though the BS-16i came with hundreds of instrument presets built in, I generally use the Ixox flute sound font as this sounds very close to my own flute.

The great thing with the Sylphyo is that there is no limit to the different ways that you can go.

Two additional forums that I found very useful when starting off were patchman and audiobus

Thank you.
I am eagerly looking forward to hearing more details.

When will it be available?
