这事让我非常担心。我刚刚下载了iPhone 3.0 SDK，但现在我无法让我的配置文件工作。以下是我的尝试:
删除所有配置配置文件 删除登录keychain 创建新的“登录”钥匙链，使它 默认的 创建一个新的证书签名请求 创建新的开发人员和分销渠道 证书在苹果开发者中心 下载并安装它们 下载并安装WWDR证书 创建一个新的配置文件和 双击它来安装
所有的证书报告都是有效的，但是Xcode仍然不能识别它们。接下来我该试试什么?
编辑:
我完全重新安装了Mac OS X，从一个新的安装安装了3.0 SDK，仍然有同样的问题。

For Xcode 13 (maybe earlier?) - The key to this is to use the "Build Settings" tab, not the "Signing and Capabilities" tab in your Target Settings. Once you are in "Build Settings", search for the "Signing" section (you can type "Signing" in the search box). There you will see a sub-section called Code Signing Identity. In that section you can click on each line and directly choose any certificate you have in your keychain. You need to do that for all of the relevant configurations (the ones that you want to upload to TestFlight/AppStore). When you go back to the "Signing and Capabilities" tab, you should see the results of what you did and the error should have gone away.
我从下面的答案中得到了灵感:https://stackoverflow.com/a/37043501/826946
但我认为明确地列出这一点可能会有所帮助。

我也有同样的问题，但是，这是由于我在我的Mac上设置了“FileVault”。我进入我的钥匙链，将“login”设置为默认值，这就解决了它。
你需要:
1)私钥和公钥。
你的钥匙链上有这个符号
2)由这些密钥的签名请求生成的证书
3)连接到该证书的配置文件
假设你换了电脑，想重新设置Xcode配置文件。你是怎么做到的?
Open Xcode, press ctrl + O to open the Organizer, and delete all provisioning profiles you might have installed already. Open keychain access, and create a signing request which you save to file (when you create the request, a private and public key is created in your keychain). Create/Update a certificate in the provisioning portal by sending apple this signing request Download and install the newly created certificate. Revoke your provisioning profiles and update them with the new certificate. Download and install the newly updated provisioning profiles.
我登录了开发人员帐户并撤销了开发证书。撤销和下载开发证书后，我双击新下载的证书，这一次私钥在开发证书下的KeyChain访问。
对我来说，只有当证书和两个密钥都在Login keychain中时，它才有效。我之前创建了一个开发钥匙链，但是Xcode管理器在那里找不到钥匙。所以我把它们移回登录，退出钥匙链工具-瞧，Xcode管理器中的错误消失了!这是在3.1.3 SDK的雪豹10.6.2上。
我也遇到了同样的问题:我第一次是在跑步时把证书下载到我的小MacBook上的。当我试图在iMac上安装证书时…然后我遇到了这一页上描述的问题。
和你们很多人一样，我花了几个小时把头发揪出来，然后我按照下面的步骤来解决它:
Close all your stuff except your webpage that should be logged into App Dev center. Open Xcode. Click WINDOW > ORGANIZER. Then click the Devices tab and select "Provisioning Profiles" on the left. That should bring up your provisioning profiles. Highlight one by one (if more than 1), right click and delete profile. Yes, just do it! Delete them all! (I kept making a new one after a new one trying to make the thing work.) From the first page you see after logging into the App Dev Center on the right side click "iOS PROVISIONING PORTAL" > (do not "launch assistant"). Instead click on the left side. Select CERTIFICATES. You will probably have just one line listed with your name/company - from there click on the right side REVOKE. Click OK to verify that's what you want to do. On the same page click DEVICES. Click the box next to your device you are trying to provision and click REMOVE SELECTED. Again click OK to verify. Wait about 2 minutes to let Apple do their thing. Now click on "HOME" that is on the left side navigation. Click "Launch Assistant" create a new app ID - call it whatever you want. Just make sure it's unique enough to know that's the one you just created because the others you've been messing with all day will not be deleted from Apples Dev Center. You should be able to follow the rest of the Assistant without troubles -- the main thing is you just had to delete your old provision profiles and start over.
好运！
