I know the basics about swift.
Now I think it's much faster to learn from well written and structured example projects instead of small Tutorials.
My Topics:
- Navigation Controller (Storyboard)
- Network communication with JSON data
- Login/Signup mechanism
I want to build an app with a login/signup mechanism followed by a navigation controller based menu. Therefore I am looking for a professional example project.
Do you know well written open source projects (perhaps github?!) to learn how to structure my code?
How could I implement the Login/Signup screens before the navigation controller? Or should I embed them into the navigation controller?
Looking forward to your answers!
Jan
Even if this question is a bit opinion-based, I would recommend you to check the tutorials from Ray Wenderlich. There are many free tutorials and even eBooks to read with all the source-code.
For your two topics there are for example the following tutorials:
Navigation Controllers in Swift
Working with JSON

I am new at Programing and to Swift. I understand the basic syntax and how to do all the common things from reading Apple's "The Swift Programming Language". But I cannot find any good documentation with examples and beginner explanations on implementing iOS Background app refresh. I have tried many Swift tutorial websites, I've turned to Google, and even searched through Apple's own web documentation, and have so far haven't had success. How does one go about implementing Background app refresh in an iOS app (using Swift)?
It depends on the type of learner you are. There are plenty of valuable resources I can recommend you. To mention a few:
Swift Programming: The Big Nerd Ranch Guide (2nd Edition)
A book that contains well explained Swift concepts where authors reinforce what you learned throughout practice and challenges at the end of each chapter. Highly recommended.
Swift 3 Essential Training: The Basics
A course from Lynda.com with high reputation in which they explain professionally Swift concepts through examples. Personally recommended.

I am looking for Pubnub alternatives in Codename One for real time communication. Are there available cn1libs for Pusher for example? If there is not one, is it possible to write a cn1lib using the existing Android and iOS libraries for Pusher?
I really like pubnub and it has a pretty generous free tier but these sort of discussions are discouraged on stackoverflow so I'll answer the question of "Is it possible to write a cn1lib using the existing Android/iOS libraries of an SDK?"
Yes. We even have a tutorial on doing this in the developer guide here. Steve also made some videos covering the subject here.
We have not explicitly tried our Ably realtime client libraries with Codename One, however they are built with portable Java and should therefore work. We are a very appealing alternative to PubNub and Pusher.

There seems to me many tutorials on how to associate files to an application, but I cannot find any information on how to open a file from my application using the iOS registered applications of that file type.
What I want is to give the user, inside my own app, the same "open-with" menu that you can find, for example, in Apple's Mail applicaton - is there any Apple API I can use for this?
Looking at an application like Dropbox, I can see they have implemented a similar feature - so there must be a way.
Thanks!
Have a look at [1], Document interaction, Previewing and opening files. Once you have an instance of UIDocumentInteractionController (using interactionControllerWithURL: and setting your delegate) you can use that to present the open menu, for example by using presentOptionsMenuFromBarButtonItem:animated:. If you provide a delegate you can also use that to supply a view for previewing the foreign document.

Basically, I have a client that wants a breadcrumb trail implemented in the navigation bar. I realize Apple doesn't recommend this behavior, but the app I'm building is for internal use only and won't be submitted to the App Store.
I need something along the lines of what AirVideo uses in their iPad App. Are there any navigation controllers that provide this functionality or any other code available?
I have done similar, but unfortunately I cannot share any code, as it is bound by NDA. But I can guide you for an easy solution.
Use UIWebView for breadcrumb.
Use CSS to show your items (like http://www.jankoatwarpspeed.com/examples/breadcrumb/#) which are enumerated from UIViewController stack
Give links, custom schema linkes, like (controller://1, controller://2 etc)
handle UIWebView requests, and use popToViewController of UINavigationController to change to selected controller
that's it
hope this helps
I think you'd have to create your own custom View Controller that holds a reference to the other views, and draws the buttons how you want.

Does anyone know a good tutorial for Tab bars?
My app is currently a "view-based" app. I need a tutorial on how to make it so that my main nib loads the view from other nibs, and when I click different tabs, it loads other nibs.
Thanks
The iPhone Developers' Cookbook by Erica Sadun has a good recipe for tabbars on page 126, including customising the bar from a list of controllers.
Have you looked around this site?
http://www.cocoadevcentral.com/
TheElements sample code in the Apple SDK -- lots of links on StackOverflow and elsewhere for combining with navigation controllers (always add nav controllers to the tab bar, not vice versa!)
