问题
I just downloaded Xcode 6.3 beta 4, and my WatchKit app now fails to build with an error:
Embedded Binary Validation Utility Error
error: WatchKit apps must have a deployment target equal to iOS 8.2 (was 8.3)
The iOS app and the project actually have a deployment target of 7.1 and always have, but we've been working with the iOS 8.3 SDK for our WatchKit component (using Swift 1.2) without issue using Xcode 6.3 beta 1, 2 and 3. This error only arose with Xcode 6.3 beta 4.
Anyone else have this error, and know how to fix it?
回答1:
Select your project settings and go to "TARGETS". Click on your Watch Kit App, select Build Settings. For the key "iOS Deployment Target" you should find "iOS 8.3". For some reason Xcode 6.3 Beta 4 wants to have this on "iOS 8.2" for "Debug" and "Release". Now your project should build as expected.
This is still true for XCODE 6.3 release!
回答2:
Target -> "appName" Watch Kit App -> search Deployment -> change iOS Deployment Target on iOS 8.2 -> run

Ran into this myself. Seems like a bug in Xcode 6.3 beta 4.
I analyzed the project.pbxproj file (in text view) of a freshly created project with a WatchKit extension. It looks like there is a setting:
IPHONEOS_DEPLOYMENT_TARGET = 8.2;
...which is missing from our projects created with earlier Xcode versions.
So I manually copied this setting into the Debug and Release configurations of my project. This error went away.
I then got another error about a version mismatch between my app and the WatchKit app target. Fixing this version mismatch allowed the build to compile clean and run fine.
I know this is a bit hacky, but I'm guessing it's relatively safe.
When searching through the project.pbxproj file, you will want to match against this search term: "_WatchKit_Extension". This should identify the area near where the new instruction should be added.

Excerpt from a fresh project:

PRODUCT_NAME = "$(TARGET_NAME)";
SKIP_INSTALL = YES;
TARGETED_DEVICE_FAMILY = 4;
"TARGETED_DEVICE_FAMILY[sdk=iphonesimulator*]" = "1,4";
};

Amazingly still true in 6.4 ;-)
All targets must be set to 8.2

I was facing same problem "iOS Deployment Target '8.3' is newer thatn SDK 'iOS 8.2' in target YUOR_PROJECT WatchKit Extension"
Here is simple solution for this issue. You can change target from .xcodeproj, just follow below steps:
- Do any change in your project or plist file (change Build/version),
- Select your modified project file
- Find '8.3' (Command+F) and replace it with 8.2.
- I have attached file for reference.
That's it.
It will help you if you have same problem like mine.

Go to Target -> Select Watch Kit App, Under deployment change value from 8.3 to
//:configuration = Debug IPHONEOS_DEPLOYMENT_TARGET = 8.2
//:configuration = Release IPHONEOS_DEPLOYMENT_TARGET = 8.2
Clean and build. Problem Solved!

Experienced same problem in simulator with Xcode 7.3.1 and could solve it by going to watch App , then go to Watch OS deployment target , there you can chose lower version based on your watch .Hope if this helps.
