For me none of the previous solutions worked. We discovered that there is an flag ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES (in earlier versions: "Embedded Content Contains Swift Code") in the Build Settings that needs to be set to YES. It was NO by default!

对我来说，以前的解决方案都不管用。我们发现，在需要设置为YES的构建设置中总是有一个标志ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES(在早期版本中:“嵌入式内容包含Swift代码”)。这不是默认的!

#2

This error can occur if something went wrong during the conversion of an Objective-C project to start using Swift. The issue is that the Linker build settings never got configured properly, so you'll have to do it by hand. Look for the Runpath Search Paths build setting and set it to:

如果在将Objective-C项目转换为使用Swift时发生了错误，则会发生此错误。问题是链接器构建设置从来没有正确配置过，所以您必须手动配置。查找Runpath搜索路径构建设置，设置为:

$(inherited) @executable_path/Frameworks

EDIT: I should also add that there has been recent spate of these errors caused by something else entirely - Apple made a change in Swift itself, starting in perhaps Xcode 6.1 or 6.1.1. The only solution seems to be to quit Xcode, destroy your certificates in Keychain Access, go to the Member Center and delete all certificates and profiles (except the profiles for apps in the Store - you can't delete them), and then start the entire certificate request process from scratch.

编辑:我还应该补充说，最近出现了一些完全由其他原因引起的错误——苹果公司在迅速地改变了自己，从Xcode 6.1或6.1.1开始。唯一的解决方案似乎是退出Xcode，在密钥链访问中销毁证书，到成员中心删除所有证书和概要文件(除了商店中应用程序的概要文件之外——您不能删除它们)，然后从头开始整个证书请求过程。

#3

I'm not really sure why this question is being downvoted, I had this problem as well when I first tried to use Swift with an existing project. An Xcode restart also fixed this for me.

我不太清楚为什么这个问题会被否决，当我第一次尝试在现有项目中使用Swift时，我也遇到了这个问题。Xcode restart也为我修复了这一点。

#4

I searched long on this issue. There are several reasons causes this issue.

在这个问题上我找了很久。造成这个问题的原因有很多。

If you are facing when you and Swift code/library in an Objectice C project you should try Solution 1-2-3

如果您在objective - C项目中与Swift代码/库一起面对，请尝试解决方案1-2-3

If you are facing this issue with a new a Swift project Solution 4 will fit you best.

如果您正面临这个问题，那么一个新的Swift项目解决方案4将最适合您。

Solution 1:

Restart Xcode, then computer and iPhone

重新启动Xcode，然后是电脑和iPhone

Solution 2:

Go to project build settings and set Always Embed Swift Standard Libraries (previously Embedded Content Contains Swift Code) flag to YES

Go to project build settings and set Always Embed Swift Standard Libraries(先前嵌入的内容包含Swift Code)标志为YES。

Solution 3:

Go to project build settings and add @executable_path/Frameworks to Runpath Search Paths option

转到项目构建设置，并向Runpath搜索路径选项添加@executable_path/框架

Solution 4:

If none of above works, this should. Apple seems to be ninja patched certificates as mentioned in AirSign's post

如果以上任何一种方法都不起作用，那么这应该是可行的。在AirSign的帖子中，苹果似乎是忍者的专利证书。

At InHouse certificates

在自身的证书

Subject: UID=269J2W3P2L, CN=iPhone Distribution: Company Name, O=Company Name, C=FR

主题:UID=269J2W3P2L, CN=iPhone发行版:公司名称，O=公司名称，C=FR。

they added a new field named OU

他们增加了一个叫OU的新领域

Subject: UID=269J2W3P2L, CN=iPhone Distribution: Company Name, OU=269J2W3P2L, O=Company Name, C=FR

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

so you should just recreate certificate and provision

因此，您应该重新创建证书和规定

#5

In my case I was trying to import a custom framework and was getting the similar error. Turns out I had to import the framework in the Embedded Binaries rather than in to the Linked Frameworks and Libraries.

在我的例子中，我试图导入一个自定义框架并得到了类似的错误。结果我不得不将框架导入到嵌入式二进制文件中，而不是导入到链接框架和库中。

Embedded Binaries are under Projects Settings -> -> General

嵌入式二进制文件在项目设置下——> ->通用

#6

For developers who have had this issue with a Adhoc/Enterprise distribution builds,

对于有过Adhoc/企业发行版问题的开发人员，

Create the production certificate from dev portal and then regenerate the distribution profile. Download and install both of them on your Mac. Ensure you selected the right profile in your Xcode build settings and rebuild your app.

从dev门户创建生产证书，然后重新生成分发概要文件。下载并安装在你的Mac上。确保你在你的Xcode构建设置中选择了正确的配置文件并重新构建你的应用。

Solution 5:

方案五:

In my case, all solutions mentioned in the answer of accfews were very helpful but none has worked. I solved my problem by adding my swift library in the section "Embedded Binaries" in the "General" section of my Project's target. Perhaps is this due to the fact that I have included my swift framework in my workspace? Whatever it compiles now! Get ready Swift, I'm here!

在我的案例中，accfews的回答中提到的所有解决方案都非常有用，但没有一个有效。我在项目目标的“一般”部分的“嵌入式二进制文件”部分中添加了swift库，从而解决了我的问题。这可能是因为我在工作空间中包含了swift框架吗?现在不管它编译!快准备，我在这里!

A simple restart of Xcode solved the issue for me.

Xcode的简单重启为我解决了这个问题。

#9

For me, the issue was due to the fact that my Apple Worldwide Developer Relations Certification Authority was invalid.

对我来说，这个问题是因为我的苹果全球开发者关系认证机构是无效的。

Download it from here: https://developer.apple.com/certificationauthority/AppleWWDRCA.cer

从这里下载:https://developer.apple.com/certificationauthority/AppleWWDRCA.cer

Drag and drop it into Keychain Access, clean the project, and run.

将其拖放到密钥链访问、清理项目并运行。

I had an Obj-C project where I started adding swift source files. The following fixed the issue for me:

我有一个object - c项目，我开始添加swift源文件。以下为我解决了这个问题:

1. Linking: RUNPATH SEARCH PATHS = $(inherited) @executable_path/Frameworks
2. 链接:RUNPATH搜索路径= $(继承)@executable_path/框架
3. Swift Compiler - Code Generation: EMBEDDED CONTENT CONTAINS SWIFT = YES
4. 快速编译器-代码生成:嵌入内容包含Swift = YES。

I just created a new project from the templates Xcode 6.3 and compared the project settings with my old original project.

我刚刚从模板Xcode 6.3中创建了一个新项目，并将项目设置与原来的项目进行了比较。

#16

If you add the three frameworks via Embedded Binaries, they will be added to Linked Frameworks and Libraries also. Delete the three entries in Linked Frameworks and Libraries will solve the problem.

如果您通过嵌入式二进制文件添加这三个框架，它们也将被添加到链接框架和库中。删除链接框架和库中的三个条目将解决这个问题。

The reasons for this occurring are many. Having just spent a fun weekend finding yet another issue that causes this (the order of code signing), I wanted to create a summary answer that brings all the possible solutions together:

发生这种情况的原因有很多。刚刚花了一个有趣的周末，我发现了另一个导致这个问题的问题(代码签名的顺序)，我想创建一个汇总答案，将所有可能的解决方案集合在一起:

1. Add Embedded Content Contains Swift Code to project. You need to set this flag if your app contains Swift code.
2. 向项目添加包含Swift代码的嵌入内容。如果您的应用程序包含Swift代码，则需要设置此标志。
3. 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.
4. 清洁项目。除了清理项目>之外，还可以删除派生数据和构建目录。查找派生数据位置的首选项。构建应该在项目文件夹中。
5. Ensure Runpath Search Paths contains @executable_path/Frameworks.
6. 确保Runpath搜索路径包含@executable_path/框架。
7. 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.
8. 确保您的证书包含您的Apple Team ID，在OU(组织单元)字段中，Apple将为您添加这个，只需撤销现有的分发证书并创建一个新的分发证书，下载、安装KeyChain，重新生成所有配置文件，下载并重新构建。
9. Xcode restart. If everything is basically good, but Xcode hasn't gotten there yet.
10. Xcode重启。如果一切都很好，但是Xcode还没有到达那里。

That's the easy stuff. If you are doing your own command line build you may be creating your own .ipa files to upload. In that case you need to ensure the following:

这是容易的事情。如果您正在进行自己的命令行构建，那么您可能正在创建要上载的.ipa文件。在这种情况下，你需要确保下列事项:

1. 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.
2. 确保SwiftSupport/iphoneos中的Swift文件版本与Contents/YourApp中的版本相同。由于Swift在版本之间还不是二进制兼容的，所以您必须确保这些版本是您构建应用程序的版本。您可以在/Applications/Xcode.app/ content /Developer/ toolchain/ XcodeDefault.xctoolchain/usr/lib/swift/iphoneos下找到这些库。
3. 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.
4. 先在库和框架上签名。您需要先共同设计库和框架文件(在.app文件夹中的框架下)，然后签署整个.app树。应用程序树必须带有授权。plist而不是框架。

Hopefully when Swift 3.0 comes out and we no longer need to bundle Swift with our apps this whole issue will go away.

希望当Swift 3.0发布时，我们不再需要将Swift绑定到我们的应用上，这整个问题将会消失。

Adding Framework as "Embedded Binary" instead of just "Linked Frameworks and Libraries" - Fixed my issue.

将框架添加为“嵌入式二进制”而不仅仅是“链接框架和库”——解决了我的问题。

I also set Embedded Content Contains Swift Code flag to YES.

我还将包含Swift代码标志的嵌入内容设置为YES。

#24

None of these solutions seemed to be consistently working for me; after every couple of successful runs, it would fail again. The "Embedded Content Contains Swift Code" flag was always set to YES for me.

所有这些解决方案似乎都不能始终如一地对我起作用;每次成功运行后，它都会再次失败。“嵌入的内容包含Swift代码”的标志总是被设置为YES给我。

Turns out I'd set Xcode to be 6.3-compatible. Changing it back to be 3.2-compatible solved it:
