Im new to MacOs and now want to use xCode as my IDE. I tried others, but they didnt seem to integrate as well. Im open for suggestions on other IDEs though if there are arguments for others. Using xCode I have following: a) In a.java I have a class A package name - which compiles b) In b.java I have a class B package name - also compiles -> project compiles but as soon as A imports B and instantiates it, the build fails. symbol B cannot be found.
