Missing Shaders on IOS RetroArch but they are there in the Android version

I noticed that the Android Retroarch lets me use a lot more shaders than the IOS version. I just got an iPhone 7 and I think it can handle some of more demanding shders like the xbr, scalenx and sabr shaders however they are missing in the IOS Retroarch. Does anyone know how to add these? Are they compatible at all?

If someone has them converted and would share these that would be great. I tried updating the shaders in retroarch but these won’t show up.
