"These extensions are distributed through native Mac applications, and Apple says they are much more secure and lightweight", 9to5mac explains of Safari App Extensions, adding that "They don't see any web browsing details, and because they run through the native Mac app, they put much less of a strain on memory and CPU performance". That's 52.2 Million news homes for the wealth of App Store apps that are being created, under these new Apple guidelines.
As bitcoin prices peaked near $20,000 in December 2017, Apple unveiled a new section of guidelines specific to cryptocurrencies and ICOs on December 20.
The iPhone isn't a great cryptocurrency miner, especially compared to special mining machines, but that doesn't mean that a surreptitious app couldn't mine tokens like Monero in the background.
Speaking to CCN at the time, Jaxx CEO Anthony Di Iorio revealed Apple had stuck to approving a select six cryptocurrencies, namely: Bitcoin, Ethereum, Dogecoin, Litecoin, Ripple and the then DAO token. The app even made it to number 3 in the finance category of the App Store before Apple pulled it down.
Wallets coded by developers enrolled as an organisation are also allowed, as are apps that facilitate transactions or transmissions of cryptocurrencies, provided these are offered by the exchanges in question. In a dedicated cryptocurrency section, the company goes on to break down in more detail what is - and, crucially, is not - permissible. It also rules that, "Cryptocurrency apps may not offer currency for completing tasks, such as downloading other apps, encouraging other users to download, posting to social networks, etc".
The guidelines do allow apps that facilitate ICOs, as long as they work with established banks and follow all applicable compliance laws.
