Vidyo app crash on Swift

Question

I have created a Vidyo iOS app using Swift with following this tutorial.

But I am getting app Crash on the following:

connector = VCConnector(UnsafeMutableRawPointer(&vidyoView),
                                viewStyle: .default,
                                remoteParticipants: 4,
                                logFileFilter: UnsafePointer("warning"),
                                logFileName: UnsafePointer(""),
                                userData: 0)

Following is the Debugger Log:

ERROR: LmiFile: [System thread]: /tmp/SDK.Release.TRINITY_4_1_20_3.build.tO3KysfAv5/source/SDK/Lmi/Os/LmiFile.c:132: LmiFileOpen_: Error opening file v\217\206: Operation not permitted

Assertion failed: (newVal >= 0), function LmiSharedPtrRefCountDecUseCount, file /tmp/SDK.Release.TRINITY_4_1_20_3.build.tO3KysfAv5/source/SDK/Lmi/VidyoClient/../../../SDK/Lmi/Os/LmiSharedPtrInline.h, line 51.

Can anyone help?

I have already added Keychain Capabilities. Still it Crashes on Second Run. First time It runs successfully if i run it Second time it Crashes. After some time if i try again it runs successfully for one attempt. I am not sure what exactly is happening — Saleel Karkhanis, Mar 01 '18 at 04:47
@SaleelKarkhanis Have you got any solution? I am experiencing the same problem. My app crashes again and again even I have followed the same mentioned steps. What is the reason? `Vidyo.io` lacking issues documentation — Tekhe, Jun 28 '20 at 13:06
For runtime crashes, I have applied this way and It looks resolved. https://stackoverflow.com/a/65793331/6135652 — iamburak, Jan 19 '21 at 18:27

The tutorial is wrong. Pass in logFileFilter: and logFileName: as regular Swift Strings.

connector = VCConnector(UnsafeMutableRawPointer(&vidyoView),
                                viewStyle: .default,
                                remoteParticipants: 4,
                                logFileFilter: "warning",
                                logFileName: "",
                                userData: 0)

The parameter type for logFileFilter: and logFileName: is const char*. You can pass a String to a parameter of this type and it will be converted for you.

Source: passing String to const char* parameter

You should be able to pass a String directly to a C function expecting const char * and it will be automatically converted to a null-terminated UTF-8 string

Make sure you are initializing the package before creating the connector:

// Initialize package
VCConnectorPkg.vcInitialize()

// Create connector
connector = VCConnector(UnsafeMutableRawPointer(&vidyoView),
                                viewStyle: .default,
                                remoteParticipants: 4,
                                logFileFilter: "warning",
                                logFileName: "",
                                userData: 0)

This fixed the issue for me. Good luck!

@Tekhe Hi, did you find any solution about your issue? I'm experiencing same thing even newly created Swift project. – iamburak Jan 19 '21 at 07:30

@iamburak Teşekkürler Aslında Vidyo güvenilir değil ve fazla dokümantasyona sahip değil. – Tekhe Jan 20 '21 at 10:43
