Trying to build the open source Signal iOS app and connect to my own server

Question

I'm trying to build the Signal iOS app to connect to my own Signal server.

I have already successfully built the Signal Android app to connect to my own server.

For both I followed the article, https://github.com/madeindra/setup-guide/tree/master/signal-ios

Using Signal iOS build 3.13.2.6 XCode 12

I was able to get the app to build in XCode after some effort. The app ran, got through the verify phone number screen (so I assume was able to hit our server successfully and I got the SMS message through Twilio) Next was the User info screen asking for name, this crashed with this error,

**Fatal error: [OWSUploadV2.swift:78 upload(data:uploadForm:uploadUrlPath:progressBlock:)]: Error: Error Domain=NSURLErrorDomain Code=-999 "cancelled" UserInfo={NSErrorFailingURLStringKey=https://xxx.cloudfront.net/, NSErrorFailingURLKey=https://xxx.cloudfront.net/, _NSURLErrorRelatedURLSessionTaskErrorKey=(**
**"LocalUploadTask <2455BE4E-077E-4FD5-B8FA-7F03FD733F70>.<1>"**
**), _NSURLErrorFailingURLSessionTaskErrorKey=LocalUploadTask <2455BE4E-077E-4FD5-B8FA-7F03FD733F70>.<1>, NSLocalizedDescription=cancelled}: file SignalCoreKit/OWSSwiftUtils.swift, line 35**

This seemed to be some kind of SSL issue, although opening the cloudfront URL in a browser or in the Android app did not have any issues.

I added the code to OWSUploadV2.swift,

class func upload(data: Data,... {
        var uploadSessionManager = self.uploadSessionManager
        let securityPolicy = AFSecurityPolicy(pinningMode: AFSSLPinningMode.none)
            securityPolicy.validatesDomainName = false
            securityPolicy.allowInvalidCertificates = true
        uploadSessionManager.securityPolicy = securityPolicy

and this seemed to solve the issue, but not sure why the issue occurred...

so this gets me to the next screen for entering a PIN, but this crashed with the error,

**2020-10-08 14:22:10:284 Signal[4202:2191958]** 💛 **[OWSWebSocket.m:605 -[OWSWebSocket processWebSocketResponseMessageAsync:]]: received WebSocket response requestId: 7765599138296075969, status: 200**

**Fatal error: [VersionedProfilesImpl.swift:234 didFetchProfile(profile:profileRequest:)]: Invalid credential: VerificationFailed.: file SignalCoreKit/OWSSwiftUtils.swift, line 35**

This is where I am stuck. Anyone have any ideas? Has anyone else successfully got Signal iOS connecting to their own server?

*** some more info

So this error occurs in line 234 of VersionedProfilesImpl.swift didFetchProfile()

in receiveProfileKeyCredential()

let credentialResponse = try ProfileKeyCredentialResponse(contents: UInt8)
let clientZkProfileOperations = try self.clientZkProfileOperations()
let profileKeyCredential = try clientZkProfileOperations.receiveProfileKeyCredential(profileKeyCredentialRequestContext: requestContext, profileKeyCredentialResponse: credentialResponse)

In the server logs I see,

Any idea what the cause could be? I can connect from Android to the same server with the same settings.

Answer 1

So I was able to get it to work in the latest XCode. I think it was meant for XCode 11, so just to get it to compile I had to make changes in,

DebugUIStress.swift

BlurHashEncode.swift

(but if anyone has correct updates to these classes please post)

To get the app to run I made changes in,

OWSUploadV2.swift

• ignored SSL certificate error

ClientZkProfileOperations.swift

• ignored profile credential errors

KeyBackupService.swift

• ignored errors

It is now running, and I can send messages, but still having some issues.

Answer 2

It seems like there's a problem uploading something to aws cloudfront. It gives you a -999 error. The -999 error is this one:

-999 is caused by ErrorCancelled. This means: another request is made before the previous request is completed.

Is the program making a request before uploading the profile details to the server?
