Breadwallet is a lite weight wallet. It does not download all blocks and transactions so it does not need to know the coinbase transaction of the genesis block and thus does not need its coinbase string. All it needs to know is the hash of the genesis block, and that is hard coded into the source code.

[HCP]

To be precise, it is the first "hash" in the checkpoint_array[] struct defined for "main net" around line 79 in the source here:

https://github.com/voisine/breadwallet/blob/e607583477870bee2c0b4490b955c3aeb49ec7d8/BreadWallet/BRPeerManager.m

The hash is: 000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f
Block Height is 0.

If you're creating a wallet for a different virtual currency, you would need to adjust all of the values in this struct to match the appropriate values in the blockchain for that currency.
