Hello World! I am very new to desiging for Apple. To date I only worked with Android UI but I want to start learning to design for Apple focused UI. iOS and iPadOS specifically because right now I am just focusing on mobile applications. I've gone through the Human Interface guidelines to find sizes but I can't seem to find anything on designing icons @1x. In MD its stated to design icons at base 24dp to cover the multitude of screen sizes. I'm struggling to find that for HI though. Are there best practices or doesn't it matter? can I still design iOS icons at 24pt by 24pt as base size? Thanks in advance.

Good day to those reading this. I am part of a team that has been developing an app for a client over the past year. After thoroughly reviewing the app to ensure all functionality is as intended, we submitted it for review in the App Store. However, the approval process is currently being blocked by the assigned reviewer. The reviewer is withholding approval based on a misunderstanding regarding the UI's interactivity. Specifically, they have interpreted a UI element as a button, while it is actually a visual indicator of an additive or subtractive transaction within the user's digital wallet. This is conveyed through up and down arrows within color-coded circles, which help users distinguish between types of transactions. For reference, we’ve included a screenshot below. Despite our clarification, it seems the reviewer is applying a biased perspective, which became more apparent following our initial appeal. The use of arrows to indicate additions and subtractions is a common design convention in apps, so we are unsure why this issue has been escalated. Additionally, the reviewer raised concerns over another aspect of the UI that suggests a rigid and subjective view of how apps should be designed. This approach has resulted in an unnecessarily prolonged review process, with little flexibility or willingness to understand our intended functionality. We respect Apple’s stringent guidelines on ensuring that apps align with advertised features, but in this case, it seems the reviewer’s personal bias is affecting the process. Is there a way to request reassignment to another reviewer for a more objective analysis?
