I am trying to build my app but it failed. I am shown the message below.
error: WatchKit Extension doesn't contain any WatchKit apps whose bundle identifiers match "com.domain.appname.watchkitapp". Verify that the value of WKAppBundleIdentifier in your WatchKit Extension's Info.plist matches the value of CFBundleIdentifier in your WatchKit App's Info.plist.
I have recently changed "com.domain.appname.watchkitapp"
to "com.domain.differentappname.watchkitapp"
.
I cannot find where to change this.
To create a unique bundle identifier, you append the name of the application to the reversed domain, for example, com. cocoacasts. scribbles . Remember that you choose the bundle identifier.
Your WatchKit extension connects to controls and views in the storyboard using WKInterfaceObject subclasses such as WKInterfaceButton and WKInterfaceLabel . These interface objects act as proxies for your storyboard elements. Use the interface elements to configure the elements in code.
Bundle name - is folder name, where your app (including executable file and all resources) will be stored (Cool Program.
You have to be careful when changing the bundle identifiers, and here's how they should be set (you need to change each identifier in the Info.plist for the iPhone app, for the Watchkit Extension and for the Watchkit App):
Set any bundle identifier as you like (the "Bundle identifier" property).
Example:
Bundle identifier: com.fruitcompany.orange
The bundle identifier here must be prefixed with the identifier of the iPhone application, like this(example):
Bundle identifier: com.fruitcompany.orange.watchkit
You also need to change the WKCompanionAppBundleIdentifier
which must match with the iPhone application bundle identifier, like this:
WKCompanionAppBundleIdentifier: com.fruitcompany.orange
The bundle identifier here must be prefixed with the identifier of the iPhone application, like this(example):
Bundle identifier: com.fruitcompany.orange.watchkit.extension
You also need to set the WKAppBundleIdentifier
under the NSExtension
attribute.
The WKAppBundleIdentifier
identifier must match with the WatchKit app bundle identifier like this:
WKAppBundleIdentifier: com.fruitcompany.orange.watchkit
Don't forget to check that your Bundle ID in project target is the same as in Info.plist!
First, let me highlight the excellent answer on this page by @DejanSkledar, as all of the locations noted in the answer are important.
That said, the precise setup in that answer was not sufficient for me. I'd like to supplement this answer and point out that since watchkit 2, there appears to be a hierarchy required as you work from the app, to the watch app, and then finally to the app extension in terms of the bundle id's.
Here are the settings in each of their corresponding info.plist files that worked for me after I found edwardmp's answer on a related issue.
iPhone App's Bundle Id: com.domain.yourapp
Watch App's Bundle Id: com.domain.yourapp.watchkit
Watchkit's Extension Bundle Id: com.domain.yourapp.watchkit.extension
As you can see, an iPhone app has a watchkit app, which itself happens to have a watchkit extension, and each of these levels must be reflected in each of their respective bundle id's.
Completing the relationships, the watch app must point to the iPhone app to which it belongs using it's (WKCompanionAppBundleIdentifier), and the watch extension must point to the watch app to which it belongs (WKAppBundleIdentifier.)
Watch App's WKCompanionAppBundleIdentifier: com.domain.yourapp
Watch App's Extension WKAppBundleIdentifier: com.domain.yourapp.watchkit
Hopefully this saves someone some time, as I had to struggle on this for a few hours :(
