Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Debug iOS w/ Xcode results crash on FAsyncNetworkWriteWorker.CheckTime

tested Engine version is 4.18.3/4.18.1, Mac, Xcode 9.2, iOS 11.2.6

procedure: downloaded engine source from GitHub(4.18.3) and do essential setup for bring up Editor. create simple(blank c++) project and generate Xcode project. opened generated Xcode project and built for iOS device by changing scheme to Debug or DebugGame and changing target to iPhone. And added -filehostip={ip.address.to.cookserver} arguments for connecting to cook on the fly server. test project is built and deployed successfully into iPhone. the black splash screen is appeared, connected to cook server and then started downloading asset - BaseEngine.ini and crashed.

call stack indicated there is problem @ FAsyncNetworkWriteWorker(const TCHAR* InFilename, FArchive* InArchive, FDateTime InServerTimeStamp, IPlatformFile* InInnerPlatformFile, FScopedEvent* InEvent).DoWork().if (CheckTime < ServerTimeStamp) [Line# 990]. CheckTime got 0(zero) and ServerTimeStamp got some value. moreover, @Line# 984, it tried to rename BaseEngine.ini.tmp to BaseEngine.ini, but it failed. and the app container has BaseEngine.ini.tmp not ini. and it crashed during print Logging into LogNetworkPaltformFile category.

does anybody have any hint for solving this problem?
