Swift example doesn't compile with Xcode 6.4

Hi @Clifton-Roberts, may I ask which cocoapods version you are using for the pod install and pod update?

[cliftonr]

Hey, @Wenzhi, I'm using version 0.38.0.

[Wenzhi]

@Clifton-Roberts It seems that Cocoapods 0.38.0 change the way of building a dynamic framework from a static library. I'm still looking at it and trying to find a way to workaround.
Are you using use_frameworks! in your Podfile? If you don't, directly use the static library should work.

[cliftonr]

@Wenzhi We do have use_frameworks! in our Podfile. Unfortunately, I don't see a way to disable this on an individual basis.

[cliftonr]

Might this fix the issue? CocoaPods/CocoaPods#3859

[Wenzhi]

Thank you for helping the investigation! I saw the issue too, but I'm not really sure if it's going to fix the problem.

The issue Undefined symbols usually is a linker issue or a library/framework search path issue. From the xcconfig files Cocoapods generated, they are all pointing to the Appboy_iOS_SDK.framework in the build folder. However, in Cocoapods 0.37.2, the file Appboy_iOS_SDK.framework/Appboy_iOS_SDK was 1.3MB, while in 0.38.0, the file is only 12KB, which makes me think the library might not be bundled in the framework properly.

I'm going to file an issue on the Cocoapods repo. I think for now, you can either downgrade your Cocoapods back to 0.37.2 to make it work, or use the manual integration. Usually the Cocoapods community respond fast; we'll also look into Cocoapods source to see if we can track down the issue.

[perotinus]

Yes, the referenced PR almost certainly won't fix this issue. It only affects header search paths, and since everything is compiling fine, that's not the issue here.

[perotinus]

Potentially relevant: CocoaPods/CocoaPods#3773

[Wenzhi]

Thank you @perotinus ! I filed a new issue CocoaPods/CocoaPods#3870 mentioning it.

Here is the fix...

We're able to fix this locally with this in our Podfile:

post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
if target.name == "Appboy-iOS-SDK"
config.build_settings["OTHER_LDFLAGS"] = '$(inherited) "-ObjC"'
end
end
end
end

[Wenzhi]

Thank you so much @jkopelioff ! I'll also test it and then update our documentation and our sample code.
