C Struct in Swift

Question

I'm attempting to use amazon-kinesis-video-streams-webrtc-sdk-c in a Swift project however I'm unsure of how to create a SignalingClientInfo struct . Specifically I'm unsure of how to properly construct the clientId :

var signalingClientInfo = SignalingClientInfo(
    version: UINT32(SIGNALING_CLIENT_INFO_CURRENT_VERSION),
    clientId: clientId,
    loggingLevel: UINT32(1)
)

Answer 1

Kind of annoying, but fixed-sized arrays in C like clientId are imported into Swift as tuples.

There's on-going discussions on adding proper fixed-size arrays to Swift, but in the mean time, there are implementation-dependent tricks you can use to construct large tuples from arrays.

See https://oleb.net/blog/2017/12/swift-imports-fixed-size-c-arrays-as-tuples/

Edit: it looks like the layout of homogeneous tuples is guaranteed . So this is safe, just annoying.
