令人惊讶的是，我所做的就是“清洁”我的项目(shift+cmd+K)，它工作了。但似乎和证书有关。

在Xcode 8中，“嵌入式内容包含Swift代码”选项不再可用。

它已被重命名为“Always Embed Swift Standard Libraries = YES”

Xcode 7.2，一台设备上是iOS 9.2，另一台设备上是9.0。两人都犯了错误。不知道是什么改变导致了它，但上面的WWDR解决方案对我来说是正确的。安装证书，问题就解决了。

下面这些步骤对我很有效:

单击项目名称(在导航器的最上方) 再次点击你的项目名称，(不是目标) 单击“生成设置”选项卡 搜索跑道搜索路径 将其值更改为$(inherited)标志(删除@executable_path/Frameworks)。

我认为苹果在试图引用Swift库libswiftCore.dylib时，已经在Swift应用程序崩溃下总结了它

引自技术问答QA1886:

Swift app crashes when trying to reference Swift library libswiftCore.dylib. Q: What can I do about the libswiftCore.dylib loading error in my device's console that happens when I try to run my Swift language app? A: To correct this problem, you will need to sign your app using code signing certificates with the Subject Organizational Unit (OU) set to your Team ID. All Enterprise and standard iOS developer certificates that are created after iOS 8 was released have the new Team ID field in the proper place to allow Swift language apps to run. Usually this error appears in the device's console log with a message similar to one of the following:

[....] [deny-mmap] mapped file has no team identifier and is not a platform binary:

The new certificates are needed when building an archive and packaging your app. Even if you have one of the new certificates, just resigning an existing swift app archive won’t work. If it was built with a pre-iOS 8 certificate, you will need to build another archive. Important: Please use caution if you need to revoke and setup up a new Enterprise Distribution certificate. If you are an in-house Enterprise developer you will need to be careful that you do not revoke a distribution certificate that was used to sign an app any one of your Enterprise employees is still using as any apps that were signed with that enterprise distribution certificate will stop working immediately. The above only applies to Enterprise Distribution certificates. Development certs are safe to revoke for enterprise/standard iOS developers.

正如AirSign人员所说，问题的根源在于内部证书的主题字段中缺少OU属性。

主题:UID=269J2W3P2L, CN=iPhone分布:公司名称，OU=269J2W3P2L, O=公司名称，C=FR

我有一个企业发展证书，创建一个新的解决了这个问题。

当升级Xcode(并随后升级到新版本的Swift)时，如果你的项目使用了用旧版本/以前版本的Swift构建/编译的框架，也会导致此错误消息。

在这种情况下，重新构建框架并重新添加它将解决问题。
