Swim 2.0 compilation error in the generated swift.h file about SecCertificateRef

Question

somewhere in our quick code there is a class with a method with this signature:

static var getCertificates : [SecCertificate] { ... } 

in the generated app-swift.h, this results in:

  @interface TrustedCertificates : NSObject + (NSArray<SecCertificateRef> * __nonnull)getCertificates; @end 

and this gives a compilation error:

  Type argument 'SecCertificateRef' (aka 'struct __SecCertificate *') is neither an Objective-C object nor a block type 

I tried adding #import before the .h file is included, but it does not solve the problem. I also tried adding import to the pch.h file, but that also does not help.

Since the fast file is generated, I cannot edit it, because it will be overwritten.

Any idea what is missing to compile it?
