A single f2f round with two person.They asked general swift language question like GCD ,NSOperation, Mapkit ,protocol, delegation , general swift syntax and question related to work done in swift

I had only one round of technical interview. Two people were interviewing me and their main focus was on SWIFT. They don't know fundamentals of iOS/Objective C. Their main focus was that you should remember all the frameworks and libraries, and all the in-build functions. They didn't ask any conceptual/logical/fundamentals related to iOS. They were asking questions related to syntax.
