[iOS] Crashed: com.apple.main-thread

See original GitHub issue

I got this crash today via Crashlytics. It seems we must to handle the code in didPickDocumentsAtURLs on main thread.

@PointCodeZero Fixed from @phatmann is on his repo. As @vonovak said above, he will fix this issue. While waiting the fix, you could easily apply above workaround by using patch-package and edit the code in RNDocumentPicker.m and add this check

        if (resolve == nil) {
            return;
        }
