Vow, I did not know that. I had tested with beta ios runtimes, then it was not possible.
So now you connect the iOS device, change code in slime, recompile and you can see live updates on the device. Is that what you mean by using slime to develop mobile apps using LW mobile?
During the beta days, one would generate a static lib, that would then get copied to Xcode project. I would assume all this is taken care of now automatically with incremental development possible.
Can you point to any documentation for Lispworks mobile with these details? Sorry I could not find any on their website.
