Question 1: So you can create one UI in Lazarus and compile this to Android and IOS?
Question 2: Are you able to compile stable and 100% working production grade Android and IOS apps with the LCL and FCL at this moment - with a single codebase?
For the first question - I do not know any development system that can do that yet (so it would be a first if FPC/Lazarus could do this).
For the second question: The only one that I know of that they can do that at this moment is Microsoft Xamarin (If FPC/Lazarus can do this please document it on a wiki page and lead me to it).
