Go into your Projects settings and remove the excess Frameworks paths in there that you don&#39;t need.
 
Here&#39;s what it looks like when I open my project&#39;s build settings:

![Open Build Settings][1]

Click on &quot;Framework Search Paths&quot; and you should find the bogus paths listed in there, which you can delete.

I sat on this issue for like more than a week before figuring out. For me the issue was a missing pod reference. And the error it was showing in xcode was weird. When I say weird they don&#39;t tell you what exactly is missing or the error.
See the image below:￼
And the issue was around the test target. I was exhausted trying out all the Framework search paths and Library Search Paths reset or removing them from the project as well. Nothing worked.

**And finally I did a guess and added the Google analytics pod to both test target and main app target and bang..it started working. Crazy!!!**
The error here in the image if you see denotes something to do with architecture. I even played around with the architecture settings.

So it&#39;s all about a pod missing in the target that you are trying to compile.
Hope this helps.

At the call to `shared_from_this()`, my server crashes with the message:

I have done some searching and it appears `shared_from_this()` is pretty particular, but I can&#39;t seem to find exactly what I need to change.

My root view controller is a UITabBarController.  I&#39;m trying to present a modal view controller over one of the tab bar controller&#39;s view controllers, but still allow the tab bar to be used to go to a different tab - in other words, I would like for the modal to only interrupt to the flow of that particular tab, not the entire app.

To do this, I&#39;ve set the presenting view controller&#39;s presentation style as &#39;Over Current Context&#39; in storyboard. The problem I&#39;m having is that after presenting the modal view controller and selecting a new tab, the presenting view controller&#39;s view is removed from the window, and isn&#39;t added back to the window when dismissing the presented view controller.  After dismissing the view controller, moving to another tab and then coming back finally puts the presenting view controller back into the window.

I&#39;ve reproduced my problem using the &#39;Tabbed&#39; template in Xcode.


![][1]

After presenting modal - I&#39;ve added transparency to the presented view controller to easily see what&#39;s going on in the presented view controller.

![][2]

Changing to second tab and then back - the presenting view controller&#39;s view has now been removed.
![][3]

Dismissing the modal leaves the presenting view controller with it&#39;s view still removed from the window.  Going to tab 2 and returning adds the view back to the window.
![][4]

I&#39;m hoping this is something simple I&#39;ve overlooked in storyboard, but the fact that I can present the modal and see the presented view controller behind it before changing tabs makes me think I have things set up correctly.

How do you loop AVPlayer in Swift?

numberOfLoops = -1 only works for AVAudioPlayer

I do need it to loop without any delay / black flash etc. That&#39;s why I&#39;m not using MPMoviePlayerViewController.

        let playerItem_1 = AVPlayerItem(asset: asset_1)
        
        let player_1 = AVPlayer(playerItem: self.playerItem_1)
        
        let playerLayer_1 = AVPlayerLayer(player: self.player_1)

I&#39;m trying to implement a table view with scrollable horizontal items (with unknown number of items) like the illustration below:

![enter image description here][1]

The UI should behave like so:

 1. At the init state the table cell shows a label and some text and the circle item pops out of the right side
 2. If the users swipes from right to left, the label and text fades out and the horizontal list (inside the cell) takes it&#39;s place


----------
I thought about using TableView and `dequeueReusableCellWithIdentifier` and creating a prototype cell, but then I need to remember the list horizontal position and init the cell properly on `cellForRowAtIndexPath` and that will probably affect performance.

**Q:** What layout would you use in order to achieve this goal, any input / tutorial would be appreciated

how is it possible to send a POST request with a simple string in the HTTP body with Alamofire in my iOS app?

As default Alamofire needs parameters for a request:


    Alamofire.request(.POST, &quot;http://mywebsite.com/post-request&quot;, parameters: [&quot;foo&quot;: &quot;bar&quot;])

These parameters contain key-value-pairs. But I don&#39;t want to send a request with a key-value string in the HTTP body.

I have a dynamic framework that is shared between an iOS application and an extension.  There is some code in that framework that references `UIApplication`, that is of course, not usable in an extension.  Those calls are completely isolated and so I am not worried about them causing problems with my extension.

Since there isn&#39;t a flag specified in the warning message, perhaps there isn&#39;t way to do it, but how do I **suppress** `warning: linking against dylib not safe for use in application extensions` when building my project?

But the function actually works. Just wondering how to solve this warning.
