How do you define the target for Specific Build Settings or Adding Frameworks?

Bắt đầu bằng cách lần theo pbxProject.prototype.updateBuildProperty và addFramework, bao gồm cả đường dẫn pbxfile/addToFrameworkSearchPaths, sử dụng extTarget.uuid được nêu trong báo cáo. Hoàn tất nghĩa là các thuộc tính build và framework tùy chỉnh được áp dụng cho target app-extension được thêm vào, thay vì chỉ áp dụng cho project chính.

I've made an App Extension with the addTarget function but even though I have the target defined like so :

// (some global paths deliberately left out but they all point correctly)
    var extFiles = [
        'NotificationService.h',
        'NotificationService.m',
        `${extName}-Info.plist`,
        'appgroupconfig.json',
        'PushExtension.entitlements',
    ];

        const proj = xcode.project(projPath);
        proj.parseSync();

        // Copy in the extension files
        fs.mkdirSync(`${iosPath}${extName}`);
        extFiles.forEach(function (extFile) {
            let targetFile = `${iosPath}${extName}/${extFile}`;
            fs.createReadStream(`${sourceDir}${extFile}`)
                .pipe(fs.createWriteStream(targetFile));
        });
        
        // Add a target for the extension
        let extTarget = proj.addTarget(extName, 'app_extension');

I cannot seem to define any buildProperties for it specifically. For example, the function

pbxProject.prototype.updateBuildProperty = function(prop, value, build)

takes in the property key the value and the build but this will only update the main project and not any of the targets defined.

The target parameter in the addFramework function doesn't appear to work either. When digging into the pbxfile that it creates to addToFrameworkSearchPaths the target is not passed or accessed in the constructor. The following code doesn't add the Framework to the target:

var opt = {target: extTarget.uuid, embed: true, customFramework: true, sign: true}
proj.addFramework(`${custom_framework_path}`, opt);

Can somebody please point me to the right direction here? I don't know what I'm doing wrong.
