Adapty SDK has its own wrapper for all kinds of errors, called AdaptyError. Basically, every error returned by an SDK is AdaptyError. It has two useful properties: originalError and adaptyErrorCode, described below.

originalError contains an original error in case you need the original one to work with. Can be SKError, NSError or just general Swift Error. This property is optional since some errors can be generated directly by SDK, like inconsistent or missing data, and won't have the original error around which the wrapper was initially built.

adaptyErrorCode can be used to handle common issues, like:

• invalid credentials
• network errors
• cancelled payments
• billing issues
• invalid receipt
• and much more

It's pretty easy to check the error for specific codes and react to them accordingly.

Adapty.makePurchase(product: product) { result in
    if result.error?.adaptyErrorCode == .paymentCancelled {
        // purchase was cancelled
        // you can offer discount to your user or remind them later
    }
}
