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.

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!

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

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.

I'm building some kind of a twitter client, but when there's a link to web in a tweet, I want to be able to display it in my app without jumping to Safari.
Is there any open source project to do it? I know I can use UIWebView, but I want to get all the features like back button, forward button, refresh, progress bar, etc.
Most of the features that you want are fairly trivial to implement using a UIWebView and a class that implements the UIWebViewDelegate protocol. Back, forward, stop, and refresh are all very easy, the only thing you can't get is an accurate progress bar. But you can detect when a page is loading and throw up a spinner or other generic loading graphic.
If you place a UIToolbar above your UIWebView with the appropriate icons on it and enable/disable/update them according to the messages that get passed to your UIWebViewDelegate implementation you can easily get an in-app experience that very nearly approximates that of a full-fledged browser.

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!)
