I am trying to rebuild my old iPhone projects on an OS X 10.6.6 iMac machine but run into several issues. One of them is the debugger when the device is set to Simulator. While the project builds with no error, the debugger does not stop at any of the breakpoints I set! The color of breakpoints is either light blue (dimmed blue) or orange (yellow) and never dark blue. Restarting Xcode does not fix the problem. What is happening? Continue reading Can’t set breakpoints in Xcode 4 and debugger does not stop →

Backup mySQL stored procedures in Java application

Question: I am a long time Mac (Xcode) programmer. My client wants me to build and distribute an Android version of the latest iPhone app that she has ordered from me, but I am a little bit uncertain. iPhone app uses the language of objective-C and the Android apps are built in Java, ergo Xcode is not the answer. I have some experiences with NetBeans Integrated Development Environment (IDE) but I heard that it is not the best choice. What tool do you recommend for an iPhone programmer?
