The Youtube Demo is crashed about ipapatch

Looks like an binary signing issue.
Would you provide the build report? It can be located in Xcode - View - Navigators - Show Report Navigator.

Now I solved it by this

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

Great job! So it's Xcode caching issue. :p
