Missing Facebook SDK for Parse using Swift - swift

This question is a lot like this one: Parse for iOS: Errors when trying to run the app except that I am using Swift in XCode Beta 4.
Essentially, when using the Parse library my app build fails, noting that I need resources from the FacebookSDK. Downloading the SDK works, but as this question on Parse's website: https://parse.com/questions/using-the-parse-ios-sdk-without-including-the-facebook-sdk notes, it adds over 1MB that I don't use.
The former question lists "Build Settings > Other Linker Flags > remove -ObjC" as a solution, but I can't figure out how to do that in this XCode version. Any help/ other solutions?
(FYI, Another solution on that page suggests creating a FBMissingSymbols.m file, but that gives me other errors because of trying to use Objective C)

A very simple solution for this is to use the CocoaPods dependency manager. If you need help setting it up, let me know. If you'd rather not, I can gladly help you get Parse set up, as I've been using it with Swift.

Errors with Alamafire SDK with XCode 6.3 and iOS 8.3

Anyone please let me know what is this all about? I am stuck since a week on this and no help from searching. I posted my query to the developer of Alamofire but still no response. Please help! I am totally confused what is wrong in the integration of Alamofire. I have followed every step and this issue is coming with XCode 6.3 as before it was running properly.
When I am adding the Framework under "Copy Frameworks", it is adding the Framework twice showing different paths but when I am Going to there location, it is taking me to the same location. Here is the screen shot.
I have also created the video for that issue. May be that can help in a better way. Please see HERE
Moreover, latest SDK contains framework for MAC OS as well but I didn't add that. I hope all the above information will help you in helping me. Thanks!
This is going to be incredibly difficult to debug without a sample project that is set up in the same manner as your actual one. If you had imported Alamofire project into your project, you wouldn't see two versions of Alamofire appear when you add it to the Copy Frameworks build phase. If you truly want to resolve this quickly, you have two options.
Option 1
Push up a sample project to Github and link it here. We can then take a look at the project and pretty quickly access what the issue is. The main reason it's so difficult here is that there are roughly 10 different things that could be the cause of the issue. Therefore, it's much faster for you to create a sample project than for us to go round-and-round (which we've already started with #Masterfego).
Option 2
Take the leap and try out CocoaPods. It is a fantastic dependency management system that will forever alleviate these annoying types of project management issues. CocoaPods itself has fantastic documentation. Also, the Alamofire README breaks down in detail how to add Alamofire to your project using CocoaPods.
Recommendation
I would highly encourage you to choose Option 2. That is definitely the fastest way forward and you won't regret moving to a more robust dependency management system. It makes managing library updates and new installations extremely simple.
If you do end up going with Option 1, then I'll take a look at your sample project and revise my answer.

Building pure Swift Cocoa Touch Framework

I'm exploring Swift with Xcode-6 and so far so good although I think the new collections need a little bit of work as I've managed to break the compiler a few times.
Problem is I'm now stuck trying to create the framework package to then use in another project. The project builds without issue and all tests pass successfully. When I go to create Archive (which I assume is what is required) I receive the error:
:0: error: underlying Objective-C module 'Sample' not found
Now I assume this has something to do with the contents of my Sample.h which tells me
// In this header, you should import all the public headers of your framework using statements like #import <Sample/PublicHeader.h>
which is fine except I have only used swift enums, structs and classes for this framework so therefore no .h files exist.
Can anyone shed some light on this one as I can't find any documentation available yet?
EDIT (7/27/2018)
The information in the answer below may no longer be accurate. Your mileage may vary.
I sat down with an engineer and asked this exact question. This was their response:
Xcode 6 does not support building distributable Swift frameworks at this time and that Apple likely won't build this functionality into Xcode until its advantageous for them to do so. Right now, Frameworks are meant to be embedded in your app's project, rather than distributed. If you watch any of the session videos or see the sample projects, this is always the arrangement. Another reason is that Swift is very new and likely to change. Thus your Swift-based framework is not guaranteed to work on the platform you originally built it on.
Slight Update
The engineer mentioned that it's not impossible to make a framework for distribution, just that it's not supported.
I was able to get past the error by going to the target for the framework and on the Build Phases tab under Headers, remove the MyFramework.h file
However I was getting the "Underlying Objective-C module not found" error when I was using a framework to share code between a containing app and an app extension, both of which were pure Swift.
Assuming you are creating a truly pure Swift module, you must disable the Objective-C Compatibility Header and any generated interface headers so the compiler doesn't go off assuming it can find an Objective-C module for the framework.
Do Not remove your public framework header. You'll get a module-map warning at link time if you do.
You might find this useful: Creation of pure swift module
In short: it's possible to make static framework, but there is one issue: it doesn't work in end user' project if "ProjectName-Swift.h" header included.
But, it works fine if you use only swift.
I think it's a bug in XCode 6, or that Apple does not allow archiving the Framework from XCode while in beta.
If you compile to profile XCode generates the framework correctly. (See the Release folder created in DerivedData)

XLET - how to create a simple xlet MHP javax.TV

I'm trying to create my first xlet project.
Can you help me?
I don't know which library I need to download.
What kind of project I have to create? (I'm using netbeans)
This site has a lot of useful info:
http://www.interactivetvweb.org/tutorials/javatv/first_xlet
You can use XletView to view your Xlet.
http://sourceforge.net/projects/xletview/
You will need to get a hold on the various API's, which is somewhat troublesome (I've heard).
But there are also other ways of getting them. For example, if you own PowerDVD, you'll be able to find BDJ.jar somewhere in that package. Add that to your classpath, and you'll be able to compile your Xlet.
If you're running Windows, you can probably develop Xlets with JavaME SDK 3.0 too (sadly not available for Linux though).

Linking error using DDMathParser (iOS 5, Xcode 4.2)

I try to add DDMathParser library to my project, but i get two linking errors. I'm a newbie in Objective-C programming, and it's still tricky for me.
Below there is a snapshot of the errors i get:
What should i do?
I also tried CGMathParser but i didn't manage to solve some errors i get.
I asked here, but i didn't get any feedback
Any advice?
Thanks
It looks like you've copied in the headers, but not actually linked the source files in. In other words, Xcode isn't compiling DDMathParser into your project.
This page on the DDMathParser wiki has information on what you're supposed to do: https://github.com/davedelong/DDMathParser/wiki/Adding-DDMathParser-to-your-project

Three20 dependency problem

I checked out the three20 source and was trying to follow this
guide to build an iphone app using the framework. Within this guide, Templates are used which I checked out too. They ought to compile properly, but I get the following error:
File /Users/myUser/programming/three20/src/build/Debug-iphonesimulator/libThree20.a depends on itself. This target might include its own product.
Did anyone ever solve that issue? I read it was about including something you want to create which is not possible. Anyway any solution I found did not help here.
I actually did not even change anything! Any ideas?
Okay I fixed this by opening the three20.xcodeproj and unchecking the target box for libThree20.a (while leaving it checked in my project that is using three20).
This has at least got me building and running, will report if any problems come up later.
