# SeedPhraseModule

SeedPhraseModule is a Swift module that provides functionality for setting, changing, getting, and deleting seed phrases for a ThresholdKey object.

To use the SeedPhraseModule in your Swift project, you will need to import the module as follows:

import tkey_pkg

| Function | Description | Arguments | Async | return |
| ------------------- | ------------------- | --------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----- |
`set_seed_phrase` | Set seed phrase to corresponding tKey | `threshold_key: ThresholdKey, format: String, phrase: String?, number_of_wallets: UInt32` | Yes | `void` |
`change_phrase` | Changes specific seed phrase | `threshold_key: ThresholdKey, old_phrase: String, new_phrase: String` | Yes | `void` |
`get_seed_phrases` | Gets all seed phrases stored in tKey. | `threshold_key: ThresholdKey` | Yes | `[seedPhraseStruct] ` |
`delete_seed_phrase` | Delete the seed phrase | `threshold_key: ThresholdKey, phrase: String` | Yes | `void` |

### `set_seed_phrase(threshold_key: ThresholdKey, format: String, phrase: String?, number_of_wallets: UInt32) async throws`
This function sets the seed phrase for the given ThresholdKey.

Parameters
- threshold_key: The ThresholdKey object to set the seed phrase for.
- format: The format of the seed phrase.
- phrase: The seed phrase. If nil, a random seed phrase is generated.
- number_of_wallets: The number of wallets to derive from the seed phrase.

Throws
- Error: An error if the operation fails.

### `change_phrase(threshold_key: ThresholdKey, old_phrase: String, new_phrase: String) async throws`

This function changes the seed phrase of the given ThresholdKey. The old_phrase parameter specifies the old seed phrase, and the new_phrase parameter specifies the new seed phrase. The function is asynchronous and can throw an error.

Parameters
- threshold_key: The ThresholdKey object to change the seed phrase for.
- old_phrase: The old seed phrase.
- new_phrase: The new seed phrase.

Throws
- Error: An error if the operation fails.

### `get_seed_phrases(threshold_key: ThresholdKey) throws -> [seedPhraseStruct]`
This function returns an array of seedPhraseStruct objects, which contain the seed phrases and their type for the given ThresholdKey.

Parameters
- threshold_key: The ThresholdKey object to get the seed phrases for.

Throws
- Error: An error if the operation fails.

Returns
- seedPhraseStruct

### `delete_seed_phrase(threshold_key: ThresholdKey, phrase: String ) async throws`
This method deletes a seed phrase from the given ThresholdKey.

Parameters
- threshold_key: The ThresholdKey instance from which to delete the seed phrase.
- phrase: The seed phrase to delete, as a string.

Throws
- Error: An error if the operation fails.
