I tried, but I must say, I don't like the syntax anymore. I used other languages for too many years, like Ruby, and they are simply more useable for me.
Nevertheless it is a powerful language, and devs who want to write apps for iOS should really learn it very well, I think.
I once had an idea to try Objective-C, but it seems Objective-C is of absolutely no use to anyone not using Apple products.<p>It seems the only use of Objective-C outside Mac world is GNUstep, which seemed too buggy to use (though maybe I’ve missed something?..).
