一.Please sign in with an app-specific password. You can create one at appleid.
原因:账号开启了二重验证,所以才导致在xcode上无法登陆
解决办法:1.在Apple官网登陆你的账号,在管理密码的地方有一个Generate an App-Specific Password,生成专用密码。
2.然后把这个密码复制下来,在Xcode上重新登录你的账号同时在application loader 上登录你的账户,不然会提示如下
ERROR ITMS-90034: "Missing or invalid signature. The bundle 'com.ShanghaiFenyin.BFGJS' at bundle path 'Payload/BFGJS.app' is not signed using an Apple submission certificate."
