My 3 year old daughter is addicted to watching cartoons/ toddler programs on YouTube. She's gained the intelligence to even unlock my phone and remembers my passcode very well. How do I get her to lose interest? I usually give in to her during meal times as I want her to finish the food.

I think you can consider having a “no gadgets at table” week. Make it into something fun. For example, you can say that this week we will be learning to appreciate having meals together. Try involving your child when you are doing her meal preparation (putting ingredients into bowls, washing and/or measuring out ingredients, setting the table etc) to get her excited and to look forward to meal time. Emphasize that she is the sous chef for the week and engage her in conversations during the meal time. Talk to her about the process of making the meal, what she enjoyed, what she would like to do the next time, what would she like to try making next. These may help distract her from wanting to watch the YouTube videos. Of course, this would mean that you will need to refrain from using any gadgets as well (and same to anyone else who is at the table with you and your child). Not sure if this will work, but no matter what you try, you will need to be firm and consistent in order for her to kick the habit. Explain the rule clearly. If she refuses to eat her meal, take it away (but offer it again at a later time, with the same rule in place). It will be difficult, tears and protests will be expected so you will need to stay firm if you want to see results. All the best!!!
