(Swift 3,4,5...) ITIDA Create Canonical JSON

See more Egypt ITIDA Examples

Demonstrates creating the canonical (ITIDA) version of a JSON document. The document in the example is the one at https://sdk.invoicing.eta.gov.eg/files/one-doc.json

Note: This example requires Chilkat v9.5.0.92 or greater.
