I particularly appreciate the emphasis on verifying localized text overflow in the article, as this is an often-overlooked aspect that can lead to App Store rejections. The suggestion to automate screenshot validation in CI using XCTest is also invaluable, as it can significantly reduce the manual effort required for testing. One potential improvement to this process could be integrating automated screenshot comparison tools to catch even the slightest visual discrepancies. Have you considered exploring the use of machine learning-based image comparison libraries to further enhance the automation of screenshot validation?
