Question 1

How to scrape a webpage with Erik in Swift?

Accepted Answer

Use Erik to visit the URL, then query DOM elements with CSS selectors via the Kanna parser. For example, extract links by iterating over doc.querySelectorAll("a") and accessing their href attributes, as demonstrated in the HTML inspection section.

Question 2

Erik vs Selenium for iOS testing?

Accepted Answer

Erik is Swift-native and integrates directly with WebKit on Apple platforms, offering lighter weight and better performance for iOS/macOS apps. However, Selenium supports multiple browsers and cross-platform testing, making it more versatile for broader automation needs outside Apple ecosystems.

Question 3

Can Erik handle dynamic JavaScript content?

Accepted Answer

Yes, Erik can evaluate JavaScript within the WebKit context and capture results. You need to set the resultErik variable in your JavaScript code to retrieve values, as shown in the evaluate example, but it may not support all browser-specific APIs.

Question 4

How to submit a form programmatically with Erik?

Accepted Answer

Identify the form element using CSS selectors, cast it to the Form type if available, and call the submit method. The README provides an example with Google search form submission, including filling input fields before submission.

Question 5

What are the limitations of Erik on macOS?

Accepted Answer

Erik is limited to WebKit, so it may not support all web standards equally. Also, on older macOS versions, https is required due to App Transport Security, which can restrict testing with local or insecure servers, as noted in the limitations.

Question 6

How to install Erik using Cocoapods?

Accepted Answer

Add pod 'Erik' to your Podfile and run pod install. For promise support, include pod 'Erik/Future'. Ensure you have use_frameworks! enabled for Swift compatibility, as detailed in the setup section.
