Whyyy would I need an old version of Xcode? Valid question – it’s not often you’ll need one. Two reasons off the top of my head though: 1) To compare with your previous experience Perhaps you’re just wanting to see what things “used to be like”. Maybe you’re struggling with the infamous “this code worked before…now it doesn’t…what changed?” and you just want to build your project with a prior version of Xcode in order to rule it out as the culprit. Grabbing an older version of Xcode could help you here. 2) To upgrade a very old project to newer versions of Swift I hit this one the other day. I ..read more

Manually Testing StoreKit Code Development Workflow Changes The previous workflow for setting up in-app purchases was a bit disjointed. You’d have to create your app in Xcode… then jump out to App Store Connect to define your app there… set up your digital products there (in App Store Connect)… and then jump back to Xcode to write your StoreKit code. Now, you can get started in Xcode, and stay in Xcode. Here’s how: Go to the File menu Click New ➡️ File Type “storekit” into the filter Click Next to add a StoreKit Configuration File ✅ From there, you get to add the digital products you intend ..read more

Setting the stage with a use case for checking the original_application_version The task appears to be simple. Suppose that… You have an existing app on the app store that’s currently at version 1.2 You want to shift to the “freemium” model by implementing in-app purchases starting with version 1.3 You want to be fair to previous-purchasers of my app (anyone who downloaded the app between version 1.0 and 1.2) Therefore… You want to check to see if someone originally purchased version 1.2 or below of your app so that you can “grandfather them in” To figure this out, you’ll need to implement ..read more

CPU cannot execute an instruction Sometimes we developers don’t play fair with the CPU. Suppose that I wrote some code that ended up telling the CPU to divide by zero. That’s… impossible… for you and the CPU. iOS is ensuring its own stability iOS may be enforcing a fundamental requirement or policy for its own stability. Apple isn’t going to let developers wreck the overall user experience of iOS. Examples: Your app takes forever to launch Your app is using too much memory iOS will opt for killing your app to protect the user’s overall iOS experience.
