Does anyone know why there aren't read-write textures on iOS? Is it a limitation of the hardware? Are we likely to see that feature in the future? (It would make my work a bit easier)
thanks!
Check page 18 in the specification on textures. You can read and write.

Yeah, but I guess Audulus had in mind read/write from the same texture during the same shader execution. Usual approach is to only read/only write. And yes, I guess that on iOS that feature may be harder to implement, since iOS GPUs are TBDRs.
