From Apple they do not want the mining of cryptocurrencies to affect users or their devices and has been on a war footing to prevent it at all costs. To do this in the new rules and policies of use implemented of the two operating systems macOS and iOS, it clearly states that cryptocurrency mining is prohibited.
This is news because previously Apple's position was clear but it did not appear in the regulations of use and now the guys from Cupertino include it to avoid problems. Use a Mac, an iPhone or an iPad to mine coins from an app and make a profit it is not legal now on the App Store or the Mac App Store.
Apple makes it very clear in the new rules of its stores
All applications including third party advertisements in them are not allowed to use cryptocurrency mining. It is clear that the cryptocurrency business is booming and part of the blame is for the popularity of bitcoin, which although it is true It is not the only virtual currency that exists but it has become the best known.
The mathematical processes that are required for mining cryptocurrencies are powerful and need good hardware for this, that is why Mac, iPhone or iPad are key to be able to mine these cryptocurrencies and Apple strongly opposes it including the new rules in usage policies.
