Question 1

How do I create a Bitcoin wallet using BitcoinKit in Swift?

Accepted Answer

BitcoinKit provides BIP39 mnemonic generation and BIP32/BIP44 key derivation. Use the Mnemonic class to generate a seed phrase, then derive HD wallet keys to create addresses for transactions, as shown in the example app screenshots.

Question 2

Does BitcoinKit support SegWit addresses?

Accepted Answer

The README lists support for P2PKH and P2SH, but SegWit (P2WPKH, P2WSH) is not explicitly mentioned. You may need to consult the source code or community for implementation status, as it might be limited or absent.

Question 3

BitcoinKit vs Libbitcoin for iOS development

Accepted Answer

BitcoinKit is Swift-native and tailored for Apple platforms, making integration easier in iOS/macOS apps. Libbitcoin is a C++ library with bindings, offering broader features but requiring more setup. Choose BitcoinKit for a pure Swift experience on Apple devices.

Question 4

How to send a transaction with BitcoinKit?

Accepted Answer

Construct transaction inputs and outputs using the provided classes, sign them with EC keys, and broadcast via the experimental SPV features. However, the README warns that SPV is under construction and may not work reliably, so test thoroughly.

Question 5

Is BitcoinKit compatible with Swift Package Manager?

Accepted Answer

Yes, BitcoinKit supports Swift Package Manager, CocoaPods, and Carthage. Add it to your Package.swift with the URL from the README, ensuring compatibility with modern Xcode projects.

Question 6

Can BitcoinKit handle Bitcoin Cash addresses like Cashaddr?

Accepted Answer

Yes, BitcoinKit explicitly supports Cashaddr encoding for Bitcoin Cash, along with base58 and other formats, making it suitable for BCH applications on Apple platforms as highlighted in the features.
