nit: Can you not forward declare this? Or include the more specific header
(Security/SecTrust.h)

Including subframework would be a Style Guide violation:
go/objc-style#Use_Umbrella_Frameworks
This is from Objective-C style guide, but it's more a planform thing rather than
a language thing.

There is no maintainable way to predeclare Core Foundation-like types and this
is how it would look:
|typedef struct CF_BRIDGED_TYPE(id) __SecTrust *SecTrustRef;|
