After renaming my project from "apple watch company tutorial" to "Project x", i had some troubles, i solved some by checking this answer, and this one
iPhone Application Info.plist:
Bundle identifier: com.company.projectx
Watchkit Extension Info.plist:
Bundle identifier: com.company.projectx.watchkitextension
WKAppBundleIdentifier: com.company.projectx.watchkitapp
RemoteInterfacePrincipalClass: com.company.projectx.watchkitextension.InterfaceController
WatchKit App Info.plist
Bundle identifier: com.company.projectx.watchkitapp
WKCompanionAppBundleIdentifier: com.company.projectx
my starter interface is named as InterfaceController
but now i am having trouble
2015-08-05 08:38:21.758 projectx WatchKit Extension[24714:1080879] WatchKit error - unable to find interface controller class '_TtC46Apple_Watch_Company_Tutorial_WatchKit_Extension19InterfaceController' to instantiate
I think my problem still related to renaming project and manually changing bundles , but i do not know what i am doing wrong.
