I’ve been building a framework and writing unit tests in GHUnit. One of my Framework’s accessor methods returns an NSInteger.

I assert the expected value in the tests like this:

GHAssertEquals(1320, request.port, @"Port number should be 1320");

When running my tests with an AppKit UI based frontend this assertion passes.

However, when I run my tests on the command line, it fails with a type-mismatch unless I type-cast my hard-coded 1320 as (NSInteger). What’s causing the difference in the way the integer is being interpreted by the compiler? Is xcodebuild on the command line using a different data-type for hard coded integers?

    Are you building your applications for different architectures (perhaps because one is building universal and one is building for one architecture)? NSInteger builds as 32-bit or 64-bit depending on the target architecture (src), which may differ from what the compiler chooses for a small constant. The cast certainly makes your intentions clear.
