I recently integrated Realm to my existing project and encountered a lot of crashes when using ASTextNode. All of them are libc++abi.dylib: terminating with uncaught exception of type realm::IncorrectThreadException: Realm accessed from incorrect thread..
Realm is not thread safe so I am making sure all accesses and to Realm objects happen in main thread. Note that it does not crash when the app is active but mostly when I open the app from background. And it looks like the crashes happen only when the attributed string contains emojis or special characters. Any idea what could be wrong?
