I'm not looking for an ObjectPascal job (because I have zero experience with it and I'm quite happy in my current position). But I'm still curious about what you do. How do you build for iOS, for example? I thought you had to use Xcode. How do you convince clients that ObjectPascal is the right solution? That is, are client concerned that you're not using Java/ C#/ C++? I've always thought Germany was fairly conservative in this respect.
