objective c - Trying to use Swift with Obj C header for Coda2 plugin. Getting error: Undefined symbols for architecture x86_64 -

-

trying build plugin coda 2.5 swift.i'm getting error:

undefined symbols architecture x86_64:   "_objc_class_$_codapluginscontroller", referenced from:       _get_field_types_powpluginviewcontroller in powpluginviewcontroller.o       _get_field_types_powplugin in powplugin.o ld: symbol(s) not found architecture x86_64 clang: error: linker command failed exit code 1 (use -v see invocation)

i have cleaned build folder. have created , added import statements project name-bridging-swift.h.

here @ project.

codapluginscontroller.h

you can find file here. https://github.com/panicinc/codapluginkit/tree/master/cocoa%20plug-ins discription: this header provides protocols , facilities implement coda text-based, syntax validator , sidebar plug-in.

codapow-bridging-header.h

// //  use file import target's public headers expose swift. //  #import "codapluginscontroller.h"

powplugin.swift

import foundation  class powplugin: nsobject, codaplugin, codasidebarplugin {     let powbundle: codapluginbundle     let powcontroller: codapluginscontroller      required init(plugincontroller: codapluginscontroller, pluginbundle: codapluginbundle) {         self.powbundle = pluginbundle         self.powcontroller = plugincontroller         super.init()     }      func name() -> string {         return "coda pow"     }      func didloadsitenamed(name: string!) {      }      func viewcontroller() -> nsviewcontroller {        return powpluginviewcontroller(nibname: "powpluginview", pluginbundle: powbundle, plugincontroller: powcontroller)!     } }

powpluginviewcontroller.swift

import foundation  class powpluginviewcontroller: nsviewcontroller, codasidebarviewcontroller {     let powcontroller: codapluginscontroller     init?(nibname: string, pluginbundle: anyobject, plugincontroller: codapluginscontroller) {         self.powcontroller = plugincontroller         super.init(nibname: nibname, bundle: pluginbundle as? nsbundle)     }     //  xcode says need this.     required init?(coder: nscoder) {         fatalerror("init(coder:) has not been implemented")     } }

i have 2 more source files. serverandhosts.swift , shell.swift don't use of classes in codapluginscontroller.h. shell.swift file set of class functions.

edit: can use swift long don't subclass codapluginscontroller.h or pass in object has been.

swift , obj-c versions of project: https://www.dropbox.com/sh/bsw8cinn7kp9kfe/aaagg_b44dbhnp5-jwj3amf8a?dl=0

the project compiles, bridging headers may not issue.

you fail @ linking stage, compiler can't find set of symbols current architecture. either mean

1) coda library not compiled architecture

or

2) linker couldn't find library @ all.

i looked @ obj-c project, , appears coda library not in project, i'm guessing #2. you'll either want move lib project somehow, or add path lib elsewhere on system in project's "library search paths"
