ios - dyld: Library not loaded: @rpath/libswiftSwiftOnoneSupport.dylib

Question

I've built a Swift framework and now I'm trying to start building a Swift iOS application that will use that framework. I'm getting this error:

dyld: Library not loaded: @rpath/libswiftSwiftOnoneSupport.dylib
  Referenced from: /Users/tdean/Library/Developer/Xcode/DerivedData/NFLApplication-ejmafvjrlqgjaabggwvadjarjjlg/Build/Products/Debug-iphonesimulator/NFLStatsModel.framework/NFLStatsModel
  Reason: image not found

I've scoured SO and found similar reports and tried the fixes listed there, including:

• Clearing out my DerivedData folder
• Restarting Xcode and the iPhone simulator
• Ensuring that Always Embed Swift Standard Libraries = YES is set, both in my framework and my application's build settings
• Ensuring that Enable Bitcode=NO is set, both in my framework and my application's build settings
• Ensuring that Runpath Search Paths is set to @executable_path/Frameworks, both in my framework and my application's build settings
• Copied all the libswift files from my Xcode installation into a local copy within my project, and added a custom build phase to copy those files into the frameworks folder.

In every case, I get the same error when I try to run my application.

• Xcode Version 8.1 (8B62)
• Apple Swift version 3.0.1 (swiftlang-800.0.58.6 clang-800.0.42.1)

I eventually got this working using a mix of fixes. I'm not sure if all of them are needed, but I'm documenting what seemed to work for me here, just in case anyone else can benefit by what I've found.

1. I have set Always Embed Swift Standard Libraries to a value of YES in the build settings tab for both my Swift framework and in the Swift application that uses the framework.
2. I have added Foundation.framework to the Linked Frameworks and Libraries section of the general tab for both my Swift framework and in the Swift application that uses the framework.
3. I have added Foundation.framework to the Embedded Binaries section of the general tab for the Swift application that uses the framework.

With all 3 of these settings in place, I am able to build and run my application without encountering this error.
