Did U.S. President Joe Biden die of a heart attack on July 1, 2023, and was his death kept under tight secrecy? No, that's not true. Biden has made several public appearances since that date, including one on the White House's South Lawn, where he and first lady Jill Biden addressed military families, veterans and caregivers on July 4, 2023, according to the text of the remarks carried on the White House website.
The claim originated in a video no longer on TikTok (archived here) that was posted on July 5, 2023, under the title "News on Biden's death#."
A headline in the silent, 10-second Arabic video read:
... Biden died of a heart attack on Saturday as [Vice President] Kamala Harris undertook his responsibilities, while the media was instructed to remain silent.
This is what the post looked like on TikTok at the time of writing:

However, Shutterstock published several images of the president at the Independence Day gathering and also in talks with the Swedish prime minister at the White House on July 5, 2023.
MSNBC also broadcast the president's comments, taken from YouTube, as Swedish Prime Minister Ulf Kristersson sat next to him on July 5, 2023. The video showed Biden reiterating U.S. support for Sweden's NATO membership.
Factbase reported the president was due to sign a proclamation to establish the Emmett Till and Mamie Till-Mobley National Monument and speak about expanding access to mental health care on July 25, 2023.
