Note: Use Application.genuineCheckAvailable along with Application.genuine to verify app integrity. Accessing the Application.genuine property is a resource-intensive operation, so do not call it during frame updates or other time-critical code.
You can use this as part of an anti-piracy check. Refer to iOS Scripting and Android mobile scripting for more information.
