The Enhanced Security capability in Xcode enables a set of features to increase the security of an app. Most notable of which is Memory Integrity Enforcement, Apple's implementation of MTE. MIE protects against memory safety issues, which will protect your users against exploits. I think it would be good to enable this early and give yourself as much time as possible to fix issues as more and more devices support it over time.
