Cocoa Touch Framework architecture issue / production build

Question

I built an iOS Framework. After I added the framework to my project and run on my device, it worked fine. But when I try to run it on the Simulator, I got some error.

ld: warning: ignoring file MyFramework.framework/Framework, missing required architecture x86_64 in file MyFramework.framework/MyFramework (2 slices)

Also got this one:

Undefined symbols for architecture x86_64:

With a list of strings/methods and such that were referenced from.

How could I fix that?

Also, I want my Framework to run on all devices/simulators since iOS7+ (Production), I've read this post here that tells me to use lipo, but I understand that I have to create an Aggregate target. I just don't have this in my Other section of XCode 6.2.

How can I do this?

So, after 2 days of search, a lot of reading on the web and mostly at StackOverflow.com I found this question:

Xcode - symbol(s) not found for architecture x86_64 (iOS Lib)

Select your Target and in Build Setting it should look like that:

Now, select the Aggregate Target, click on the Build Settings and should look like that:

If you want to better understand how to create a framework, read this question and the answer of this question, there is a lot of information there, this is what helped me:
