Delphi uses FPC 2.6.0 to do the iOS compilation.
I have Xcode 4.3.1 installed (no idea why the version is not displayed in the list).
FPC 2.6.0 doesn’t recognize it. Apparently it only works with Xcode up to 4.2.
Apple only offers XCode 4.3.1 for Lion.
So I’m asking you – can I really use Lion to compile FireMonkey iOS applications? Doesn’t seem so.
