Suppose we have 2 apps on iOS phone. What can we do to let one app send real-time data to the other one? Is there any best practice? Is it against security? Cheers.

You can use AppGroups to achieve this. See this question.

    It requires extension. What if the two apps are not from one developer, like a middleware sending data to any third-party apps that are interested in the data? – C Luo May 18 '17 at 01:46
  • Continuing C Luo's comment, .... or a driver from a manufacturer to add support for their device to your app? Such as a Bluetooth Health Device (95% of which are proprietary). – Brian Reinhold Aug 24 '20 at 12:22
