Cannot install Watch app

问题:

When trying to test a Watch app on the Watch, in XCode I get the following warning

Watch App xcodeproj TARGETED_DEVICE_FAMILY contains a value incompatible with the target type.

Looking at the Device logs, it says:

(Error) WatchKit: validateWatchKitApplicationInfoDictionary, invalid UIDeviceFamily value

What am I missing?

回答1:

Modify Targeted Device Family

1. Open file PROJECT.xcodeproj in your project folder
2. Open file project.pbxproj
3. Replace value of TARGETED_DEVICE_FAMILY: "4" for watchkitextension, "1,4" for watchkitapp
4. Replace value of "TARGETED_DEVICE_FAMILY[sdk=iphonesimulator*]" = "1,4" for watchkitapp

e.g.

回答2:

Your Watch Extension should have a TARGETED_DEVICE_FAMILY of iPhone whereas the Watch App target should have TARGETED_DEVICE_FAMILY of 1,4 like this:

I had a similar problem on a project that was created with an Xcode beta. I ended up creating a new test project and going through side by side and comparing all the settings.
