Twitter is a great way to stay up-to-date on the latest news and happenings. But if you want to watch videos posted by Twitter users, you’ll need to download them first. To download a video from Twitter on your iPhone, first open the app and search for the video you want to download. Tap on it to open it in the app’s main screen. Next, tap on the three lines in the top left corner of the screen. This will open up a menu where you can select “Download Video.” Tap on “Download Video” and then select which device you want to save the video to. You can either save it to your iPhone’s Photos library or send it directly to your iPad or iPod touch. ..
