Guide in Docs folder is not updated

The "Result_NoneChannelMonitorUpdateErrZ" type does not exist for the version of ldk-swift that is currently in use for swift developers

[danielnordh]

Here are more issues showing in Xcode if I use the setup guide verbatim:

FeeEstimator

• Method does not override any method from its superclass

Logger

• Value of type 'Record' (aka 'Bindings.Record') has no member 'get_args'

BroadcasterInterface

• Method does not override any method from its superclass

Persist

• Method does not override any method from its superclass

Filter

• Method does not override any method from its superclass
• Cannot find type 'Option_C2Tuple_usizeTransactionZZ' in scope
• Value of type 'WatchedOutput' (aka 'Bindings.WatchedOutput') has no member 'get_script_pubkey'
• Value of type 'WatchedOutput' (aka 'Bindings.WatchedOutput') has no member 'get_outpoint'
• Value of type 'WatchedOutput' (aka 'Bindings.WatchedOutput') has no member 'get_block_hash'

Init

• filterOption - Cannot find 'Option_FilterZ' in scope
• chainMonitor - Incorrect argument label in call (have 'chain_source:broadcaster:logger:feeest:persister:', expected 'chainSource:broadcaster:logger:feeest:persister:') -> Fixed by replacing 'chain_source' with 'chainSource'
• keysManager - Incorrect argument labels in call (have 'seed:starting_time_secs:starting_time_nanos:', expected 'seed:startingTimeSecs:startingTimeNanos:') -> Fixed by replacing 'starting_time_secs: timestamp_seconds, starting_time_nanos' with 'startingTimeSecs: timestamp_seconds, startingTimeNanos'
• keysInterface -> Fixed by replacing .as_KeysInterface() with .asKeysInterface()
• userConfig - Missing arguments for parameters 'channelHandshakeConfigArg', 'channelHandshakeLimitsArg', 'channelConfigArg', 'acceptForwardsToPrivChannelsArg', 'acceptInboundChannelsArg', 'manuallyAcceptInboundChannelsArg', 'acceptInterceptHtlcsArg' in call -> Fixed by inserting arguments, but not sure what values they should be
• channelManagerConstructor - Incorrect argument labels in call (have 'network:config:current_blockchain_tip_hash:current_blockchain_tip_height:keys_interface:fee_estimator:chain_monitor:net_graph:tx_broadcaster:logger:', expected 'network:config:currentBlockchainTipHash:currentBlockchainTipHeight:keysInterface:feeEstimator:chainMonitor:netGraph:txBroadcaster:logger:') -> Fixed by replacing with correct names
• network: - Cannot convert value of type 'LDKNetwork' to expected argument type 'Network' (aka 'Bindings.Network')
• latestBlockHeight - Cannot convert value of type 'Int' to expected argument type 'UInt32' -> Fixed by replacing 'latestBlockHeight' with 'UInt32(latestBlockHeight)'
• networkGraph - Incorrect argument label in call (have 'genesis_hash:', expected 'genesisHash:') -> Fixed by using expected name
• networkGraph - Missing argument for parameter 'logger' in call -> Fixed by adding missing argument and using the defined logger

@danielnordh Did you fix above issues? I created new project and added DirectlyLinkedBindingsApp code and LDK (0.0.114) using SPM. But getting complication issues.

[danielnordh]

Did you fix above issues?

I have paused my LDK integration and will instead use the upcoming ldk-node package that should have a simplified setup.

[KunalDev]

Thank you for letting me know about the upcoming ldk-node package. May I ask if you have any information on when it will be released and available for use? An estimated timeline would be helpful for me to plan accordingly.

I'm not personally involved in the building of it, but best place to look is the repo of the rust version https://github.com/lightningdevkit/ldk-node

And the ldk-node channel in the LDK discord https://discord.com/invite/5AcknnMfBw

Hey @danielnordh, could you share what you currently have done for your LDK-swift integration? I would be interested to see. Thanks!

Considering it doesn't work, I'm not sure it's much use to you, but where I got to is in this LDK Manager wrapper class. Unfortunately it is missing most of the meat in the important method overrides. https://github.com/bdgwallet/dailywallet/blob/ldkmanager/dailywallet/LDK/LDKManager.swift

A better place to look might be this example by @jurvis, particularly the node file: https://github.com/jurvis/Surge/blob/main/Lightning/Sources/Lightning/Node.swift
