[!] The following Swift pods cannot yet be integrated as static libraries:

The Swift pod `barcode_scan2` depends upon `MTBBarcodeScanner`, which does not define modules. To opt into those targets generating module maps (which is necessary to import them from Swift when building as static libraries), you may set `use_modular_headers!` globally in your Podfile, or specify `:modular_headers => true` for particular dependencies.
