stringWithFormat oddity

If I do this (iOS):

var i:Integer;
NSLog('i: %ld',i);

Then the compiler gives me this warning:

warning NW1: Format specifier "ld" (nr 0) expects a "Int64/UInt64" while "Int32" was passed as a parameter

If I then do this:

var i:Integer;
NSLog(‘i: %ld’,Int64(i));

then I get this warning:

warning NW1: Format specifier "ld" (nr 0) expects a "Int32/UInt32" while "Int64" was passed as a parameter

That’s somewhat confusing (to me, at least!). If I change i to be an NSUInteger then it’s fine, but that doesn’t work if I’m passing a type enumerator as an integer as I have no idea whether it is 32 or 64.

It’s both, if you are building s universal app. Odds are the different messages come from the different build phases - one version fails for 64-bit, the other for 32.

The workaround is to cast to 64 always, and use lld.

Thanks, yes that worked.

also note that %d is always 32bits (and Integer is also always 32bits)
