Tealium Learning Center

Hello, I am trying to get sessionId from volatileData and notice that when I call getData() my app crashes: let config = ... let tealium =  Tealium(config: config) let data = tealium.volatileData()?.getData()   <-- crash here let sessionId =  data[TealiumKey.sessionId] as? String however I notice if i do the same in the init() endCompletion, everything works: let tealium =  Tealium(config: config) { (_) in {   let data = tealium.volatileData()?.getData()      let sessionId =  data[TealiumKey.sessionId] as? String } Can anyone tell me what i'm doing wrong? Cheers. d. ... View more
