The Swift grpc example does not seem to work. I made sure to do a pod install and opening xcworkspace. I have attached an image showing the errors.

I've been messing around with the objective-c/swift Grpc branch for a while.

You might get some luck posting what your "pod install" looks like in Terminal.

I have provided my pod install below.

$pod install

I can reproduce this and I'm currently working on it.

Ok, caught the problem. XCode 7.1 needs these setting from the gRPC podspec:

ss.xcconfig = {

'USE_HEADERMAP' => 'NO',

'ALWAYS_SEARCH_USER_PATHS' => 'NO',

'USER_HEADER_SEARCH_PATHS' => '"$(PODS_ROOT)/Headers/Private/gRPC"',

'HEADER_SEARCH_PATHS' => '"$(PODS_ROOT)/Headers/Private/gRPC/include"'

}

but as the pod install warnings show, the project is configured to override USER_HEADER_SEARCH_PATHS (and it overrides it with "Pods/**" which is super wrong).

Sorry for the long time to update; I've been fighting this issue for a full week now so I thought I'd report:

I've found fixes for using gRPC on:

a Swift app, as a static library,
an ObjC app, as a framework (as a static library it's always worked).

The fixes are hacks; I need to create issues for them on the Cocoapods repo. I haven't been able to make it work yet on a Swift app as a framework (I think I've just hit https://github.com/CocoaPods/CocoaPods/issues/3767).

I'm going to clean up the work, create tests for all of this, and send a PR.

Thank you Jorge for the update.
