Why did you think that? The docs say

The NS_BUILD_32_LIKE_64 preprocessor macro works in a different manner. It declares NSInteger to be long (instead of int) and NSUInteger to be long unsigned int even on 32-bit portions of the source base.

and that’s all they say. Nothing about CGFloat

use explicit casts.
