MarqueeLabel | automatically adds a scrolling marquee effect | iOS library

I'm trying to accomplish the following:

I've followed the answer in this question, but I get the image below:

This is the code for the collection view controller:

I'm new to iOS, i already have Alamofire and MarqueeLabel on my Podfile and now trying to add GoogleMaps, it keeps showing this message,

I've downloaded the latest Xcode beta 4. When I build I'm getting the same error with 3 of my pods:

I have an array of 115 objects containing name and photo url string from Firebase. Printing the data shows results so i know its pulling data correctly.

The problem is the Cells are never populated by the data.

If i add a print(name) inside the class DJProfileCell: UICollectionViewCell it never gets called so i believe thats where the issue is.

I am trying to merge React-Native into a swift application. I created a new podfile and added in all the dependencies. After trying 'pod install' many times, it will still not install the pods.

I have tried to delete the podfolder and also delete the node folder and run 'npm install' again. I have tried updating my ruby software. Everything that I can find on GitHub and on here that seems applicable I have tried.

I know this question has been asked a lot of times and there are many probable answer, but none of them helped me to get over my problem.
Here some possible solution's which I am trying out.
Solution1 Solution2 and many suggested solutions on the site.

I am also using Notification service & Notification Content Extension in my project.Also I am using firebase for push notifications.
From the time since I have integrated .xcconfig files to manage staging and production configuarations using This tutorial all the problems have started.

As you can see above i trying to code an simple(!) subclass of UILabel to make an marquee or scrolling text effect if the text of the label is too long. I know that there are already good classes out there (e.g https://cocoapods.org/pods/MarqueeLabel), but i want to make my own :)

Down below you can see my current class. I can't also fix an issue where the new label(s) are scrolling right, but there is also a third label which shouldn't be there. I think it's the label itself. But when i try the replace the first additional label with that label i won't work. I hope it's not too confusing :/

It's important to me that i only have to assign the class in the storyboard to the label. So that there is no need go and add code e.g in an view controller (beside the outlets). I hope it's clear what i want :D

So again:

• Simple subclass of UILabel
• scrolling label
• should work without any additional code in other classes (except of outlets to change the labels text for example,...)

(it's my first own subclass, so feel free to teach me how to do it right :) )

Thank you very much !

It's by far not perfect, but this is my current class:

That's a hard one. I updated Firebase from 3.x to 5.8 and migrated my project from Swift 3 to Swift 4.2. Now I'm getting the following error:

I am using following code for creating scrolling text using pyqt. Also I am creating rectangular box in my UI using QPainter. The problem is that the code as such works fine but after sometime it hangs. The message stops scrolling while other part UI is functioning. I used code from earlier stack overflow question for scrolling text Marquee effect. Following is the some part of my code
