In the coming days I feel as if we are going to see a lot more threads about the new privacy features in iOS 14. Apple has a video overview of a lot of the new stuff [1]. I suggest watching it (at 2x speed - they talk very slowly). Especially at 16:30 where they emphasize that SDKs are part of your app and that you the developer are fully responsible for the data collection of any SDK you include in your app. This is going to be a huge problem for a lot of developers.
That's it. I'm switching to iOS. Android is like child's play when it comes to privacy compared to the features introduced just in this version of iOS. I'm sure I'll hate the lack of customizability but at least the privacy features are solid.
If by problem you mean end of laziness then sure. You can no longer drag and drop FB or google analytics SDK into your project, type in a few lines of glue code, email the product owner that you have added tracking capability into the app and head down to the pub to spend some of that well earned six figure developer salary.
Now I am gleeful about this because it's win-win for me as a consumer and software engineer. Better privacy and use of my data as a consumer. More $$ work as an engineer when all those analytic pipelines need to be re-architected and rebuilt.
