对我来说，之前的解决方案都没用。我们发现在构建设置中有一个标记ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES(在早期版本中:“嵌入式内容包含Swift代码”)需要设置为YES。默认是NO !

我在使用带有生产证书的Ad Hoc(或企业)移动设备时遇到了这个问题。切换到开发证书和移动供应解决了这个问题。

我试了上面给出的所有答案，都没用。

终于工作后更新到优胜美地

发生这种情况的原因有很多。刚刚度过了一个有趣的周末，发现了另一个导致这个问题的问题(代码签名的顺序)，我想创建一个总结答案，将所有可能的解决方案放在一起:

Add Embedded Content Contains Swift Code to project. You need to set this flag if your app contains Swift code. Clean project. In addition to a Project > Clean you can also delete the DerivedData and Build directories. Look under the Preferences for the location of DerivedData. Build should be in your project folder. Ensure Runpath Search Paths contains @executable_path/Frameworks. Ensure that your certificate contains your Apple Team ID in the OU (Organization Unit) field Apple will add this for you, just revoke your existing distribution certificate and create a new one, download, install on KeyChain, regenerate all provisioning profiles, download those and rebuild. Xcode restart. If everything is basically good, but Xcode hasn't gotten there yet.

这很简单。如果你正在进行自己的命令行构建，你可能会创建自己的.ipa文件来上传。在这种情况下，您需要确保以下内容:

Make sure the version of the Swift files in SwiftSupport/iphoneos is the same as the version in Contents/YourApp.app/Frameworks Because Swift is not yet binary compatible between version, you must ensure these versions are the one that you built your app with. You can find these libraries under /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphoneos. Sign the libraries and frameworks first. You need to codesign the libraries and framework files (under Frameworks in the .app folder) first and then sign the entire .app tree. The .app tree must be signed with an entitlements.plist but not the frameworks.

希望当Swift 3.0问世时，我们不再需要将Swift捆绑到我们的应用程序中，这个问题就会消失。

最近又开始得到这个错误。虽然前两个答案在过去为我解决了这个问题，但这次没有一个建议的答案有效。我注意到错误说:

 Reason: no suitable image found.  Did find:
/private/var/mobile/Containers/Bundle/Application/8D8E5347-940A-4724-ACFE-33DF4C4DCB37/your.app/Frameworks/libswiftCore.dylib: mmap() errno=1 validating first page of '/private/var/mobile/Containers/Bundle/Application/8D8E5347-940A-4724-ACFE-33DF4C4DCB37/your.app/Frameworks/libswiftCore.dylib'

所以我试着从设备上删除应用程序，然后我就可以重新构建并运行了。

添加框架为“嵌入式二进制文件”，而不仅仅是“链接框架和库”-修正了我的问题。

我还设置嵌入内容包含Swift代码标志为YES。
