根據(jù)官方文檔，加入realm.framework靜態(tài)庫到工程之后，編譯，有可能提示如下錯誤：

Undefined symbols for architecture arm64:
  "_inflate", referenced from:
      realm::util::compression::inflate(char const*, unsigned long, char*, unsigned long) in Realm(compression-iphoneos.o)
  "_deflate", referenced from:

那么加入庫"libz.tbd"即可解決問題，官方文檔并沒有提示要加這個庫。
