Swift header file not created correctly when building with Xcode 10.2

[Alexs1987]

Swift 5 seems to have changed the format of the generated Swift header file by adding the following conditionals dependent on the architecture:

#if 0
#elif defined(__arm64__) && __arm64__
...
#elif defined(__ARM_ARCH_7A__) && __ARM_ARCH_7A__
...

When building the iOS platform with cocoapods-binary the generated Swift header file only has __arm64__ and __ARM_ARCH_7A__ but does not have any conditionals for the simulator architectures and therefore the Swift parts of the framework can't be used by Objective C code in the app.

Similar issue in Carthage - Carthage/Carthage#2718
