Embarcadero has released a hotfix which patches some issues with the IOS8 Simulator support in Delphi XE8 Firemonkey. It is not quite clear what issues are patched with the hotfix but there are a number of updated files. Three of the updated files are libsqlib.dylib, libpcre.dylib, and libmidas.dylib. Two source files which get patched in the hotfix are System.RegularExpressionsAPI.pas and FMX.Platform.iOS.pas. I’m not sure about the other files but I believe libsqlib.dylib is for accessing Interbase and possibly the embedded versions of Interbase so if you are having trouble with those in the IOS8 Simulator this may fix that up for you. I successfully applied this Hotfix and deploying to IOS8 Simulator still works for me. If you are looking for the TEdit/TListView fix for IOS Simulator this is not it. David I. from Embarcadero has a blog post about the hotfix and the contents of the readme here.
