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"

[Closed] IPA size much bigger when built on a Mac vs PC


We have been cooking/packaging our iOS game using a PC. Once uploaded to iTunes Connect the download size in TestFlight is around 63MB.

Unfortunately we discovered that metal shaders don't get pre-compiled if cooking/packaging is done on PC and we get some hitches in game as the shaders are compiled at runtime.

To fix that we tried cooking/packaging on the Mac. The hitches are gone during gameplay, but now our download size from TestFlight has grown to 129MB.

The shader cache more than doubled in size, but only from 400k to 900k.

Why is the cooking/packaging process on Mac creating larger IPAs?
