Happy 2019 everybody! Hope everyone has had a great holiday.

Sorry for the late invite, but are you ready? Time for 2019 first meetup! This time, we're hosted by Truecaller.

Guven Iscan and Claus Jorgensen are both iOS developers at Truecaller. In their talk dubbed "Building a messaging platform with GRPC and Protobuf", they will show how they built a cross-platform networking layer using HTTP 2 socket communication.

Daniel Kennett is a long-time Cocoa developer who went from working at Spotify to being an indie developer, selling his photography app Cascable. He will hold, in his own words, a rant about how the overuse of extensions in Swift is bad and everyone should feel bad. Most probably in his usual wholehearted way :)

Alek Åström is an iOS developer turned aspiring entrepreneur. He will show us the magic of SnapshotTesting, a new testing framework for UI components and more!
