I just signed up and will buy bytes. The ios app wallet is not available in the app store, is that correct?
https://github.com/byteball/byteball/blob/master/building-for-ios.mdBuilding Byteball for iOS
Apple takes cautious approach to new cryptocurrencies and didn't approve our app for the App Store (yet). Fortunately, if you own a Mac, you can build and install Byteball for your iPhone yourself:
Download Xcode (4.5GB), if not already.
Sign up for Apple Developer Program (if not already), it's free.
Download Byteball Xcode project, it contains all the source code necessary to build.
Unzip and open Byteball.xcodeproj in Xcode.
Select a Team in the project properties.
Connect your iPhone to your Mac via USB.
Build Byteball by clicking Play button in Xcode.
Read more detailed instructions (for another app). It is one of the easiest ways to try open-source apps that are not on the App Store.
...except the fact that the xcodeproject file has not been made available on Github since 1.10... you cant really use that system to generate the latest iOS app for your iphone :/
