WatchKit application will not compile: "error: WatchKit Extension does not contain any WatchKit applications"

Question

There are several posts on this subject, but none of the proposed solutions work in my case. I am trying to integrate WatchKit into a simple sample application (I tried a couple now) following Apple's instructions. When I compile, I get the following error message:

": WatchKit Extension does not contain any WatchKit applications. That the WKWatchKitApp value in your WatchKit App.plist application is set to" YES ".

I successfully compiled and ran the Apple Watch Directory example, so I know that everything works with the iPhone to view perspective. Something seems to be wrong when I try to integrate with an existing application. I saw posts here on this topic (for example, the WatchKit application does not start on the simulator ), but none of the fixes work in my case; all packet identifiers look correct. Note. I am trying to compile and run on an iPhone 6 not on a simulator. Any suggestions?

Answer 1

This error occurred to me when I changed the package id of my main iOS application. This is what I did in the project explorer

• Under WatchApp -> plist

  WKCompanionAppBundleIdentifier ==> Give the id of the iOS App (com.xxxx.appname)

• Under WatchApp Extension → plist NSExtension-->NSExtensionAttributes-->WKAppBundleIdentifier ==> Give the id of your watchkit app (eg: com.xxxx.appname.watchkitapp)

this fixed a bug for me.

Answer 2

The main causes of this error,

1 Incorrect application package identifier for viewing in the plist file of the watchkit extensions.

2. There is no watchapp.app dependency in the watchkit destination.

I noticed this on Xcode version 8.2.1. Here is how I fixed it.

Go to “WatchKit App” → Build Settings → Packaging → Product Name

Change it so that any line differs from the current one. I agreed that this is a bizarre decision, as indicated in the link below.

Answer 4

The settings below worked for me

• In the main App Info.plist

Package ID: com.domain.WatchKit-table

• In Watchkit App Info.plist

WKCompanionAppBundleIdentifier: com.domain.WatchKit table

Package ID: com.domain.WatchKit table. watchkitapp

• WatchKit Extension Info.plist

NSExtension> NSExtensionAttributes> WKAppBundleIdentifier: com.domain.WatchKit-table.watchkitapp

Package ID: com.domain.WatchKit table. watchkitapp.watchkitextension

Note: my package id has * as the third component. WatchKit table is my project name

Answer 5

I noticed this with xcode 10.0 after changing the build number.

Clearing the build folder, closing xcode and reopening helped me.

Answer 6

In my case, I had a problem creating an extension library. In fact, it was not built, and I had two errors: 1. From the linker about the lack of an extension library. 2. From Xcode about the "missing" key NSExtensionPointIdentifier.

Binding bug fixes also fixed this message.

Answer 7

I encountered this problem in XCode Version 10.2 (10E125) , I have XCode Version 10.2 (10E125) that when I changed the identifier of the WatchkitApp package, one key in the watchkitapp extension did not change and remained the same package identifier.

list path: /Users/.../YourXcodeProjectFolder/Project/YourWatchkitExtensionFolder/info.plist

The problem arose here:

 <key>NSExtension</key> <dict> <key>NSExtensionAttributes</key> <dict> <key>WKAppBundleIdentifier</key> <string>com.applecode.water.watchkit</string> </dict> <key>NSExtensionPointIdentifier</key> <string>com.apple.watchkit</string> </dict> 

The WKAppBundleIdentifier key was made a problem, so I changed it myself.
