Unable to read xcode(8.2.1) project

[wajahatch888]

I am using following code to read xcode project and add one header file But it fails.

var xcode = require('xcode'),
    fs = require('fs'),
    projectPath = '/Users/Wajahat/Desktop/JASONETTE-iOS/app/Jasonette.xcodeproj/project.pbxproj',
    myProj = xcode.project(projectPath);

// parsing is async, in a different process
myProj.parse(function (err) {
    myProj.addHeaderFile('testheader.h');
   
   

    fs.writeFileSync(projectPath, myProj.writeSync());
    console.log('new project written');
});

I am getting following error

TypeError: Cannot read property 'path' of null

Can anybody tell what i am doing wrong? Thanks in advance.

try first to parse, e.g.

var xcodeProject = xcode.project(projectPath);
xcodeProject.parseSync();
var buildPhase = xcodeProject.addBuildPhase(...

@hypery2k apologies for the slow reply. You need to specify a group to add the header to otherwise it your header is added to a group named "Plugins" which you probably don't have in your project?

myProj.addHeader(path, opt, group)
