Like other popular social media apps, TikTok has a scanner – called TikCode – to track people in your immediate area. Although the scanner itself is easy to use (just scan another user's TikCode), there is actually a faster way to access your iPhone than by combing your TikTok settings.
For this trick you don't even have to open TikTok first. Long press or 3D instead Touch the TikTok app on your home screen and then wait for the Quick Actions menu to appear. Select "Scan" if this is the case. Once you've done that, TikTok immediately launches the TikCode scanner, so you can add people right away.
