Please see issue #9 .

Yeah but when I do cmd+f and I search kuglee, I see nothing to replace with my apple indent

These are the places where you have to change to identifiers:

• TermiWatch WatchKit App's Info.plist:
  WKCompanionAppBundleIdentifier

• TermiWatch WatchKit Extension's Info.plist:
  NSExtension > NSExtensionAttributes

Thanks for helping me, I look at both theses places but I've already replace them :( still don't work

Try to clean your project (Xcode > Product menu > Clean Build Folder).

done, still don't work

Do you have com.(me).TermiWatch.watchkitapp in NSExtension > NSExtensionAttributes > WKAppBundleIdentifier?

Also, select the project in the Navigator and check it the Target have the correct Bundle Identifiers.

I have this: com.(me).TermiWatch.watchkitapp, but I don't know how to "check it"

It's in the How to Install guide > Configuring the project section.
The targets have to have the following bundle identifiers.

• TermiWatch: com.(me).TermiWatch
• TermiWatch WatchKit App: com.(me).TermiWatch.watchkitapp
• TermiWatch WatchKit Extension: com.(me).TermiWatch.watchkitapp.watchkitextension

IT WORKED ! I was missing this one com.(me).TermiWatch.watchkitapp, thank you so much for helping me so far <3

No problem. I'm glad I could help.

@kuglee I'm still getting the same error after checking 3 bundle identifiers...
