"Warning: unable to build chain to self-signed root for signer" warning in Xcode 9.2
提问by Chewie The Chorkie
I'm attempting to migrate an Xcode project to another computer. It gives me the warning "Warning: unable to build chain to self-signed root for signer" and when it runs it crashes immediately similarly to what is shown in this Stack Overflow:
我正在尝试将 Xcode 项目迁移到另一台计算机。它给了我警告“警告：无法为签名者构建到自签名根的链”，当它运行时，它立即崩溃，类似于此堆栈溢出中显示的内容：
App working on simulator but not on iPhone( dyld`__abort_with_payload dyld`_dyld_start)
应用程序在模拟器上运行但不在 iPhone 上运行（dyld`__abort_with_payload dyld`_dyld_start）
My issue seems similar to what is described on the Apple Developer Forums here: https://forums.developer.apple.com/thread/86161

except the suggestions of deleting certificates and re-adding them, re-adding my account and restarting didn't seem to help. I have removed my developer cert for the second time and now I don't see it coming back, and I'm at a loss of knowing how to get it back since my dev portal doesn't appear to have a place to download it like it used to.
除了删除证书并重新添加证书的建议外，重新添加我的帐户并重新启动似乎没有帮助。我已经第二次删除了我的开发者证书，现在我看不到它回来了，而且我不知道如何取回它，因为我的开发门户似乎没有地方下载它像以前一样。
I've also tried deleting the derived data folder several times.
我也多次尝试删除派生数据文件夹。
e: I've determined ANY project on this computer results in the same crash and warning.
e：我已经确定这台计算机上的任何项目都会导致相同的崩溃和警告。

I have been facing same issue for days now. Finally i solved it by just changing my root CA from Key Chain Access. View in System/ Login key chains. which certificate authority is being used as signer for your personal provisioning profile's certificate. Enter a valid CA certificate and you are good to go! Hope it helps. Ciao!
我已经面临同样的问题好几天了。最后，我通过从 Key Chain Access 更改我的根 CA 来解决它。在系统/登录密钥链中查看。哪个证书颁发机构被用作您的个人配置文件的证书的签名者。输入有效的 CA 证书，一切顺利！希望能帮助到你。再见！
