如果你的项目有cocoapods和不同的方案，试着运行pod update，这为我修复了它。

我通过删除派生数据来解决这个问题，这一次它工作正常。尝试Xcode 7.3.1GM

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:
/private/var/mobile/Containers/Bundle/Application/5D8FB2F7-1083-4564-94B2-0CB7DC75C9D1/YourAppNameHere.app/Frameworks/libswiftCore.dylib

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。

对我来说，它只是我目标的名字:

我把它重新命名为:MyApp。同样的问题出现了。 但是我在构建设置窗口中看到，我的产品模块名称已经更改为这样的myapp -什么。 所以，我删除了点在我的目标名称(MyAppSomething)和问题消失了。

对我来说，我忘记在Podfile中添加两行代码来目标“Runner”

target 'Runner' do
   use_frameworks!
   use_modular_headers!
end

添加这些代码解决了，希望对你有所帮助!

我在运行Swift测试时遇到了这个问题(但不是我的应用程序)。事实证明，测试需要在测试目标的Runpath Search Paths构建设置中有更多的@executable_path/Frameworks。以下设置Runpath搜索路径对我来说很有魅力:

$(inherited)
@executable_path/Frameworks
@loader_path/Frameworks
