Cocoapods : target has transitive dependencies that include static binaries when installing 'VialerSIPLib'

I'm trying to install an objective-c Wrapper for Jsip 'VialerSIPLib' and use it in my swift project here is my pod

platform :ios, ’10.0’

use_frameworks!
target 'EMedicalAdmin' do
pod 'ObjectMapper', '~> 2.1'
pod 'Alamofire', '~> 4.3'
pod 'SwiftyAvatar', '~> 1.0'
pod 'AlamofireImage', '~> 3.1'
pod 'Eureka', '~> 2.0.0-beta.1'
pod 'JSQMessagesViewController', :git => 'https://github.com/jessesquires/JSQMessagesViewController.git', :branch => 'develop'
pod 'PKHUD', '~> 4.0'
pod 'Firebase/Core'
pod 'Firebase/Messaging'
pod 'ImageSlideshow', '~> 1.1.0'
pod 'SwiftyJSON'
pod "FlexibleSteppedProgressBar"
pod 'BTNavigationDropdownMenu', :git => 'https://github.com/PhamBaTho/BTNavigationDropdownMenu.git', :branch => 'swift-3.0'
pod 'VialerSIPLib'
end

but i get this error when installing :-

target has transitive dependencies that include static binaries:

and if i remove

use_frameworks!

from my podfile it would work but all my other swift based pods won't work

so, i'm left with using only this one pod (VialerSIPLib) or Use all my other pods except it

Solution

Please add this to your podspec: s.static_framework = true This is available from cocoapods version 1.4.0.

It worked for me.!!
