Does watching porn invalidate the fast

Assalamualaikum Mufti saab. Unfortunately last year during Ramadan I watched pornography while fasting. I was not fully sure whether it would break my fast or not. I became very regretful and began searching whether it broke my fast or not. Some people said yes while others said no. Mufti saab I come to you with great shame asking this question. I have repented to Allah (swt) and have sat in the company of Ulama to try and better myself. Did my fast break? If so, how do I make up for it? One more question if I may: While I was fasting today I made ablution and put water in my mouth and then spat it out. I then proceeded to pray my salat and because I was thirsty I intentionally swallowed my spit. I was not sure whether there was water in the spit or not. If I kept on spitting until I was sure the water was gone from my mouth I would become even more thirstier. Did my fast break also Mufti saab? Jizakallah for taking your time to read this question. Wa'asalamualaykum.
