I am bringing in the Wormhole library via Cocoapods. Everything works as expected on iPhone 5 and 6, but on 4s simulator it crashes at launch with the error below. Looks like all the architecture settings are correct and in-sync between app and used frameworks.
Library not loaded: @rpath/MMWormhole.framework/MMWormhole
