Our staff now has a decent grasp of the new Swift programming language, and the basic Cocoa libraries. It will take a few months to get fully up to speed, but we are ready to start coding.
Our contractor wrote quite a bit of startup code in Objective-C, and we are reviewing it now to see how much can be salvaged. We may need to start over entirely, but it’s worth spending a week to understand his code, and decide what to keep (and how to merge it). If nothing else, we need to learn enough Objective-C so we can link our C++ to Swift.
It took us about 2 months to move Goldenseal from Mac OS 9 to X, and 2 weeks to move it from PPC to Intel. Unfortunately, this is going to be a bigger transition. Hard to estimate right now, but it will be months, not weeks or years. A lot of the time will be “learning curve” that will pay off when we start writing apps for iPhone and iPad.
