I am getting this error when building on my iPhone. I am able to build on the simulator. I have redone all my provision files however I still can't build on my iPhone. My Xcode is like this

Is this a framework problem or a signing issue? This did not happen in Xcode 6. Thank you.

Solution

  • I have this problem before for accidentally revoked my certificate. Then all my swift projects have this problem. There are two ways to solve this:

    Click on Product → Clean (or CMD + Shift + K)

    Or by manually cleaning the Xcode setting files: 

    rm -rf "$(getconf DARWIN_USER_CACHE_DIR)/org.llvm.clang/ModuleCache"
rm -rf ~/Library/Developer/Xcode/DerivedData
rm -rf ~/Library/Caches/com.apple.dt.Xcode
