The bridge to happiness
Everyone is talking about the flatness, but I love to look around and see some of the smaller wins on the developer side of an iOS SDK.
If you have areas of your application where “scripting” would fit in, then this could be a fantastic solution. Areas such as gaming have already done this for a long time. Even though the “apple rules” talk about not being able to download code and run it, games have been doing just that for ages (in Lua, or other languages). Anecdotally Apple seems to not care any more (don’t quote me on that / your mileage may vary).
I haven’t been able to go deep and see what limitations exist, but man, I am excited to see what can be done.
