Hi friends, I am .NET developer, developing desktop applications for windows for the last two year. Now, my client asked me to do a Mac application, which i have done for windows previously. Before i start developing the application, i want to make sure that which programming language will best suit for me. I heard about 1)Real Basic (Which is from Real softwares) 2)Objective C (Which is from Apple) And as far as concerning my application, it's a very big..long term...PROJECT. So it will be using many more latest techonlogies...and it should adhere with latest technologies.... And it needs language which need many more functinalities...like 1)Parsing/Creating PDF(possibly word, excel) file.. 2)Connecting to remote servers 3)More interface elements and related functionalities.. 4)Multiple client connection 5)Lots of database transaction 6)Embedded web browser But my friends are telling that RB don't have many more functionalities and interface elements. So i have plan to go with Objective C. My thinking is as iPhone SDK is from Apple,they will have many more functionalities needed for a BIG Mac application. But i am not sure.. Are there any other languages than RB and Objective C for developing a Mac application? Could you guys please advice me on which language i should choose for developing a BIG mac application? Please advice. Thank you. Good Day!
