I\'ve been reading all the issues about the error:
dyld: Library not loaded: @rpath/Bolts.framework/Bolts
Referenced from: /private/var/mobile/Containers/Bun
In order to have cocoapods generate the build phases Check Pods Manifest, Embed Pods Frameworks and Copy Pods Resources:
1 - Go to build phases and remove any custom modifications. I had to remove everything under the Link Binary With Libraries phase.
2 - Do a pod deintegrate (Or just remove the files yourself)
3 - Run a new pod install
This worked for me. Without the first step, it never did.
