How to use libxml in Swift? [closed]

Answer 1

I found that you can leave out importing 'libxml2.2.dylib' if you add '-lxml2' to OTHER_LDFLAGS.

Answer 2

I 've made it work with CommonCrypto https://github.com/onmyway133/CommonCrypto.swift but libxml should be the same. Things to keep in mind

module.modulemap

Read http://clang.llvm.org/docs/Modules.html#module-map-language

Create a folder named libxml2 (in my case, it is at the same directory as my project file), then create a module.modulemap file inside

module libxml2 {
  header "/usr/include/libxml2/libxml/tree.h"
  export *
}

Here I add just tree.h, but you can add more for your need

SWIFT_INCLUDE_PATHS

Go to Target Build Settings, add this into Import Paths

${SRCROOT}/libxml2

HEADER_SEARCH_PATHS

Read Why am I getting this "libxml/tree.h file not found" error?

Go to Target Build Settings, add this into Header Search Paths

$(SDKROOT)/usr/include/libxml2

Answer 3

To get this working with my project in Xcode 6, I navigated to "Build Settings" for my project, and selected my target. I then searched for "Header Search Paths" in the Build Settings, and added the following line to both debug and release:

$(SDKROOT)/usr/include/libxml2

You will have to create a custom module map file containing the header of libxml/tree.h like so :

module libxml [system] {
    header "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/include/libxml2/libxml/tree.h"
    export *
}

Then you place this file (module.modulemap) inside a folder -module for example- and add it to your project's and target's build settings.

You can now use @import libxml; in your code.
