Apple showcased a range of new software titles like iOS 12 and macOS 10.14 Mojave during its brief WWDC 2018 keynote speech last week, then, in the days thereafter, the company went on to spend a wealth of hands-on time engaging with iOS, macOS and other developers, familiarizing them with all the new features and capabilities coming later this year to Apple products.
The latter has five subsections that further describe what apps can and cannot do in terms of cryptocurrency.
After the cryptominer was found to contain buggy code that made CPU usage on users devices spike, Apple pulled Calendar 2 from the macOS App Store.
The upshot of the new rules is that while Apple will permit cryptocurrencies to exist on its platforms, it's adding requirements to stop scammers and individuals from exploiting App Store customers, while making explicit that it's blocking developers from eating Apple device processing power for mining activities.
Revised wording in the App Store review guidelines notes that Apple is banning apps which "run unrelated background processes, such as cryptocurrency mining".
"Apps should not rapidly drain battery, generate excessive heat, or put unnecessary strain on device resources", the company stated in the paragraph banning cryptocurrency mining processes from running in the background. According to the rulebook, only official apps developed by the exchange itself can provide such services. These, Apple writes, "must come from established banks, securities firms, futures commission merchants, or other approved financial institutions and must comply with all applicable law".
Apple additionally wants to ensure the seriousness of Initial Coin Offerings, cryptocurrency futures trading, and other crypto-securities or quasi-securities trading.
Moreover, Apple will no longer allow reward-based crypto marketing with App Store listed apps.
