multipeer-connectivity

I am working with Multipeer connectivity. It works fine when all devices are connected to same wifi. I have 1 master and 5 slaves devices . I want to do connectivity with personal hotspot but everytime the connection will declined. This is my code : class SessionManager: NSObject, MCSessionDelegate, MCBrowserViewControllerDelegate, MCNearbyServiceAdvertiserDelegate, MCNearbyServiceBrowserDelegate { func browser(_ browser: MCNearbyServiceBrowser, foundPeer peerID: MCPeerID, withDiscoveryInfo info: [String: String] ? ) { browser.invitePeer(peerID, to: mcSession, withContext: nil, timeout: 10) }

When I write the output stream in multipeer connectivity from audio buffer data I got the error Cannot invoke initializer for type UnsafePointer<_> with an argument list of type (UnsafeMutableRawPointer) I found the many solutions, but this solution not helpful for me. My code is: func send(_ buffer: AudioBuffer) { print(buffer.mData!) print(buffer.mDataByteSize) outputStreme?.write(UnsafePointer(buffer.mData), maxLength: buffer.mDataByteSize) } Thanks in advance..:) Please check the official reference when some sort of spec changes has affected with your code. In your case AudioBuffer.mData
