Now, let's talk about some debugging. It's pretty common to use the console to print our variables when debugging, but have you tried to print json data from your responses when you are trying to figure out what's coming from the server?

SWIFTUI & ARKIT
SwiftUI is gaining traction and it won't be long until we start using it on a daily basis, but we’re seeing a trend where the use of AnyView has become very common. There are situations where its use is required, but we must avoid it if we can. Check out Avoiding SwiftUI’s AnyView by John Sundell.

NEWS & EVENTS

Here is where Apple recommends the use of Identity Pinning. A Strong way to secure all of this valuable information.
Finally, how about some content we can read while our apps compile? Here are some nice sources of fun.
