Cannot compile FMDB pod

[ButkiewiczP]

I have an app, using the FMDB pod, and building on one machine.

Cloning my app to another identical machine (same software versions, OS version, etc, etc), yields a whole bunch of compilation errors when trying to build or test my application now during the Compiling FMDatabase.m phase.

Some example errors:

FMDatabase.h:568:4: expected a type
[11:47:06]: ▸ - (FMResultSet * _Nullable)executeQuery:(NSString*)sql, ...;

FMDatabase.m:329:9: use of undeclared identifier 'FMResultSet'
[11:47:06]: ▸ FMResultSet *rs = (FMResultSet *)[rsInWrappedInATastyValueMeal pointerValue];

There's roughly 20 of these errors, but they only seem to crop up on certain machines with no obvious signs as to why. Does anyone have any insight into this?
