| // Common customizations/sanitizations of the platform defaults for our projects. | |
| // | |
| // For compatibility reasons, the iOS platform has a couple of not–so–sensible defaults. | |
| // This file collects, and annotates the deviations from these defaults. | |
| // | |
| // :NOTE: Some of the settings herein may be redundant for newly created projects/targets: | |
| // Xcode’s project/target templates take several (but not all!) of these issues into account. | |
| // However, for uniformity it is probably more useful to simply delete the entire warning section in the Xcode project, and then set them up using the standard warning flags. | |
