I believe this works as intended.
Yeah, I can't tell if it's intentional or not... when filing stuff like this, please try to include an explanation of why you expect it to work that way.
Is it like that in MC? If it was a recent change to MC, I'm not sure we should treat it as a bug or file it here at all; we can probably assume it's on the developers' schedule. OTOH, if it's always been like that in MC but never was in PE, it may be a bug after all...
I think,this happens because sword take the instant destroy blocks, like torches, an entity? And, why only swords? I tried a hoe, but the hoe's durability did not decrease.
I have tried this on PC, and it works as intended. Swords do not take damage.
Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
Cleaning up all the old issues - please reply if this affects 0.9.3.
Still an issue in 0.12.0 Win 10. Breaking grass and other instant-mine blocks reduces durability on tools and weapons.
