618: Type System Says No

StoreKit Transition

The transition from StoreKit 1 to StoreKit 2 aims to simplify in-app purchase implementations, but challenges remain. John Siracusa highlights that while StoreKit 2 automates many processes, developers still face complexities in implementing business logic correctly 1. He notes that Apple's sample app, Backyard Birds, attempts to showcase StoreKit's capabilities but falls short in providing comprehensive guidance 2.

Even if you memorized every line of code, even if you copy and pasted the code samples, they have them in the transcripts, the code. That's not sufficient for you to. I know, I just did it.

Siracusa emphasizes the need for better documentation to truly leverage StoreKit 2's potential 1.

   

Documentation Issues

Documentation challenges significantly hinder developers working with StoreKit. Casey Liss and John express frustration over the lack of clear, step-by-step guides for implementing StoreKit features 3. They argue that Apple's WWDC videos, while informative, often assume prior knowledge, making it difficult for developers to fully grasp new updates 4.

If you miss one or two things when you attend the junior year high school class and they started teaching you calculus, if you don't know pretty much everything that came before it, you have a serious problem.

Siracusa compares this to math education, where missing foundational concepts can lead to significant challenges later on 4.
