In my project I'm using both Swinject and SwinjectAutoregistration pods. Both are usually declared as '2.0.0' versions like so:
pod 'Swinject', '2.0.0'
pod 'SwinjectAutoregistration', '2.0.0'
But in order to build my project in the beta version of Xcode 9, I need to take a specific branch of the Swinject github repo, as stated here. The new declaration looks like this:
pod 'Swinject', :git => 'https://github.com/Swinject/Swinject.git', :branch => 'swift4'
When I then try pod update I have dependencies error. I believe SwinjectAutoregistration declares a dependency to Swinject 2.0 so I have different sources for the same pod.
Is there a way to tell cocoapods that this specific source of the pods acts like the 2.0 version?
Well, it seems like specifying the source as the github repo instead of the cocoapod repo for this particular pod works.
I added this line before the target 'MyGreatApp' do line:
source 'https://github.com/Swinject/Swinject.git'
I must specify that this works for this particular pod, but might not work for other cases. The fine folks behind Swinject have a fix for an Xcode (9, beta) bug on a branch in their github repo that is not in the cocoapod repo.
So this answer works in this case, but unfortunately this might not be as generic as I hoped.
