Line Items for Product Variant

[Rahul_Kumar]

I am working on iOS app with shopify SDK. I am trying to add a custom line item with a product variant, i am able to add it as an option and as an line item for a particular product variant. but after my successful order, it doesn't show on my dev console. Is this how we add line item or custom property with iOS SDK?

I'm not sure what you mean. The Mobile Buy SDK does not support custom line items. The only thing you can do is add a product variant. You cannot change the content of the variant. All the collections, products, variants, options, and option values that you download from Shopify are read-only. You can try to change them, but the changes will be ignored.
