  Few things are as frustrating as a rejected App Store submission, especially when the rejection triggers are external dependencies. If you are integrating the Start.io (formerly StartApp) SDK into an iOS application targeting iOS 17 or later, you have likely encountered   ITMS-91053   or   ITMS-91056 . These warnings indicate missing or incorrect privacy manifest signatures. Since Spring 2024, Apple requires specific third-party SDKs—particularly those involved in advertising and analytics—to include a  PrivacyInfo.xcprivacy  file. This file must explicitly declare the data types collected and the specific "Required Reason APIs" accessed by the code. This guide details the root cause of these validation errors within the context of the Start.io SDK and provides a rigorous, code-level solution to ensure your binary passes static analysis. Root Cause Analysis: The Supply Chain Shift To fix this efficiently, you must understand the mechanism behind the rejec...

  Few things trigger developer anxiety quite like a crash occurring immediately upon application launch. It is even more frustrating when the crash stems from a third-party dependency intended to generate revenue, such as the Vungle (Liftoff) SDK. If you are seeing immediate terminations with  SIGABRT  or  SIGSEGV  signals during  didFinishLaunchingWithOptions , or sporadic crashes when the app backgrounds, you are likely facing a race condition during SDK initialization. Furthermore, missing  SKAdNetworkItems  configurations can cause the SDK to abort initialization entirely, leaving your app in an unstable state. This guide details the root causes of these initialization errors and provides a thread-safe, robust architectural pattern to resolve them in Swift. The Root Cause: Why Vungle Crashes on Launch To fix the crash, we must understand the underlying friction between the iOS application lifecycle and the Vungle SDK's initialization requireme...
