xpringkit's Issues

Web Socket for account balance?

I'm not familiar with your repo or grpc but I wanted to know how to call the subscribe command on the web socket? I want to call it for both account and transactions. Similar to how ethereum does it..

Is this implemented in your library? If not, how am I supposed to update the balance when a balance is updated on the chain? Just call the function again? Seems like alot of work went into the proto's and grpc but the functionality that developers need to execute a proper application on the blockchain is missing? Or am I missing something?

[FEATURE] Payment Channels?

Any timeline or interest in payment channels?

Locally Sign Transaction

Is there a way to build and sign the transaction locally?

Support WatchOS build target?

Add invoiceID to transaction?

Is there a way to add the invoiceID to the transaction?

Better Error Handling

If you call getBalance on a new address is returns

The operation couldn’t be completed. (XSwiftGRPC.RPCError error 0.)

If you review the error the status message is:

Account not found

This made me go crazy. Apparently it's the error you receive when the balance is 0.

I'm just putting this here so someone else searches for it.

Get Transaction Data??

Is there any way to get the transaction data from the send call? It's recommended by ripple that the transaction data be persisted in the database.

XRPClient "Send" functionality clarification

Sorry to bother but I had a question concerning the XRPClient.send function. I am a little confused on the "From" parameter because it is asking for a "Wallet" and not an Address. The only way to create a wallet variable is by using Wallet(seed: "seedID"). How would I create a "wallet" variable if I have the senders wallet address as a string? Do i need to get a seed value from the senders address? Not sure if I am missing something... sorry, still somewhat new to this..

This is an error I am getting:
"Cannot convert value of type 'Address?' (aka 'Optional') to expected argument type 'Wallet' "

Change sendPayment parameter in IlpClient

This is a small nit, but the IlpClient.sendPayment API takes a String as its second parameter for paymentPointer. Although at the call site this label will be to: , we should align the parameter name with Xpring4j and set it to destinationPaymentPointer.

API should be:

sendPayment(
        _ amount: UInt64,
        to destinationPaymentPointer: String,
        from senderAccountID: String,
        withAuthorization bearerToken: String
) throws -> Org_Interledger_Stream_Proto_SendPaymentResponse

How do I run the GRPC Server?

This sdk is confusing to say the least...

As a developer I would expect the same access to the ledger that is given over the api through web sockets or rpc. I'm under the impression this is not the case with grpc and I need to run my own adaptor over my local server to interact. Is that correct?

Error Cloning SDK

I got the following error when cloning and trying to run the clone?

Greetings!

Hello engineering team working on the Xpring suite of mobile SDKs,

My name is Alex Smith and I'm interested in working with your SDKs on a current project of mine. I've been following the progress being made here in the XpringKit SDK for iOS since that's ecosystem I'm most familiar working in.

I come from a background of working with financial institutions with my previous company Flybits in which I was an employee. My days were spent managing a suite of 7 SDKs not too dissimilar from what you have with your own. Distribution was a pain since ABI stability hadn't really been introduced yet (as you probably know, customers at financial institutions are slow moving and must allot proper funding to make any updates). So, the latest version of Swift we could support was Swift 4.2 but we supported multiple versions of Swift simultaneously for our suite of SDKs.

In short, Flybits' SDKs provide a mechanism for personalizing user experiences using contextual elements from the array of sensors in the device and creating rules to determine what content a user should be presented with.

That's some background of the kind of work that I've done recently. On the side, I'm playing around with some NLP and the new things introduced at WWDC this year, mostly to do with SwiftUI.

In the near future, I plan to share what it is that I'm building but in the meantime I'm interested in seeing this project succeed both internally to the company and externally in terms of adoption with developers like me!

I've read your guide on contributing but I realized that I'm unable to create PRs since I'm not a white-listed team member/contributor.

How might I become a contributor to this project? Also, if I have questions more broadly speaking about the SDKs and their direction, what might you suggest as the appropriate avenue? Create an Issue here like I am now, post something to the Xpring forums, email, or something else?

By the way, you may have seen me making comments on some PRs already; however, until now I hadn't introduced myself.

Thanks for your time learning about me and your consideration to add me as a contributor!

grpc-swift is no longer maintained

The library for SwiftGRPC is no longer maintained and they use a completely different library. I was having trouble integrating XpringKit into google products.

I had to Podfile install SwiftGRPC with a gRPC-Core version of 1.28.0 to get my pods to install correctly.

I was wondering if you are going to upgrade XpringKit to the new NIO protocol and the new grpc-Swift library?

Utils.encode - Unable to call the encode function

I keep getting the error " Value of type 'Utils' has no member 'encode' " and cannot call the "encode" function. Any help on being able to encode a classic address into an Xaddress would be awesome!
I am using the code below within a function (per the documentation):

let xAddress = Utils.encode(classicAddress: address, tag: tag)

pod XpringKit

Please make sure you have the correct access rights and the repository exists.

Migrate to AssertJ

Prepend "Bearer " to auth token

This won't change anything functionally, but in order to abide by correct standards, the ILP SDK should add Bearer to the beginning of all auth tokens, if they do not already have them.

Similarly, we should wrap bearerToken in a class called IlpCallCredentials, which will do this for us and make the bearer token more strongly typed.

Same as xpring-eng/Xpring-JS#228

Failed to install pod

Hello!
First, there was a problem with the submodules. I had to add ssh keys to make cocoapods clone submodules. Now, I can't install pod due to compilation issues. Maybe you can add the precompiled binaries to facilitate pod installation? A lot of time needs to be spent just to install the pod. In the future, we will have many problems with our CI-machine. Thank you

Translate Hermes gRPC errors into XpringIlpErrors

Currently, if an error occurs during the network call from DefaultIlpClient to Hermes, we are just throwing that error. GRPC errors are not very pretty, and should get caught and rethrown as XpringIlpErrors.

This should look something like this:

XpringKit/XpringKit/DefaultXpringClient.swift

Line 206 in 030223f

public func accountExists(for address: Address) throws -> Bool {

CocoaPods could not find compatible versions for pod "gRPC-Core":

I'm working on my fork and I use swift 5 with Google Firestore Dependencies. I'm now running into the issue using pod install with the following errors:

[!] CocoaPods could not find compatible versions for pod "gRPC-Core":
  In snapshot (Podfile.lock):
    gRPC-Core (= 1.21.0)

  In Podfile:
    Firebase/Firestore was resolved to 6.14.0, which depends on
      FirebaseFirestore (~> 1.8.2) was resolved to 1.8.3, which depends on
        gRPC-C++ (= 0.0.9) was resolved to 0.0.9, which depends on
          gRPC-C++/Implementation (= 0.0.9) was resolved to 0.0.9, which depends on
            gRPC-Core (= 1.21.0)

    XpringKit (from `/Users/denisangell/projects/xrp/xpringKit/XpringKit.podspec`) was resolved to 1.2.1, which depends on
      SwiftGRPC was resolved to 0.4.3, which depends on
        gRPC-Core (~> 1.11.0)


You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * changed the constraints of dependency `gRPC-Core` inside your development pod `XpringKit`.
   You should run `pod update gRPC-Core` to apply changes you've made.

I believe this is a dependency issue... So I went https://github.com/grpc/grpc-swift and found a depreciation issue?

‼️ Please use the nio branch ‼️
gRPC Swift versions v0.x based on gRPC-Core will soon be replaced with a re-implementation based on SwiftNIO.

We strongly suggest that new projects use the re-implementation from the nio branch which we consider to be production ready.

Please see DEPRECATION.md for more information.

My goal is to get all of this up to swift 5.

Happy Hollidays!!

PayID & ILP

Hey guys,

I wanted to get some additional. Are payment pointers and PayID the same? Can payID be used for ILP or is the PayID, just a record of the users accounts?

Also, for something like a ethereum smart contract, how would I use the ILP to interact with this smart contract? Also, on the ILP it looks like there is a way to "handshake" much similar to that of a payment channel. Is the "Payment Channel" possible to be used by the ILP?

Thank You!!
