Summary: How do I make a podspec that includes a project itself using a Podfile?
I've build a Mac framework and as part of the workspace I use a cocoapod library, OpenSSL-Universal. The linked library is all written in C, whereas my project is in Swift, so I created a directory called SwiftSSL and in that I put a module.modulemap file like so:
module SwiftSSL {
header "../Pods/Headers/Public/OpenSSL-Universal/openssl/ssl.h"
header "../Pods/Headers/Public/OpenSSL-Universal/openssl/crypto.h"
export *
}
That let's me import SwiftSSL in my project and not use a bridging header file.
It seems to work fine via my unit tests. Now I want to turn this whole thing into a pod of its own, but I can't for the life of me figure out how to write the podfile so that the calling projects don't need to also include OpenSSL-Universal in their installations.
I tried adding these lines to my podspec:
s.source_files = "**/*.{h,swift}"
s.exclude_files = "Classes/Exclude"
s.preserve_paths = "SwiftSSL/module.modulemap"
s.xcconfig = {
"SWIFT_INCLUDE_PATHS" => "$(SRCROOT)/SwiftSSL/**",
'HEADER_SEARCH_PATHS' => "$(SRCROOT)/Pods/Headers/Public/OpenSSL-Universal",
'LIBRARY_SEARCH_PATHS' => "$(SRCROOT)/Pods/OpenSSL-Universal/lib-macros"
}
But when I pod spec lint my file I get tons of build errors:
