Making a `UIView` line go half rounded on center of itself

I'm struggling with a problem:
I did create an UIView with subviews inside to make my own UIToolBar.
I added a UIView which acts like a delimiter line on top of it.
Then I decided to make one of the subviews rounded on center. But I need to find a way to "curve" the delimiter UIView.
Actually I have:

Is there anyway to fullfill my goal programmaticaly in swift ?
I thought about importing an UIImageView and make the images according to the differents iPhone size but is there any other solution ?
I solved a similar problem by sandwiching a dark gray circle image behind the toolbar, and a light gray circle image in front of the toolbar but behind the button. It's a hack but it works perfectly if you match the colors, and it's easier than doing path drawing.

Text over image in Uiview

sorry, if this might been asked before.
I am laying out a viewcontroller for a new app. It will include a photo (UIImageview) which fills the nearly all of the screen and it should include a scrollable UITextview which should fill the bottom right corner of the screen and including a description of the photo.
So i have two views over one space and i would like to give the Textview priority over the UIimage. Is there any other way then reducing "Alpha" of the UIImage to make the Textview visible ? Tinkered around with Conten Hugging Priority and Content Compression ... to no avail.
Any help would be appreciated
Thanks
The easiest way to make sure text is easily readable over any image, I suggest setting a background of color rgba(.2, .2, .2, .8) or something similar and then using a white font color.
Thanks everybody for trying to help me out... I have found the solution... It is perfectly ok to overlay Views in Interfacebuilder but then it is imperative to use a background color for the overlaying textview with reduced opacity.

Swift xcode horizontal line

I wonder what the best way to create a horizontal line is?
I have a few labels / text and I would like to add a horizontal line between them. More or less like a when using twitter bootstrap.
Right now I am using a UIview and setting it as 1 in height with a black background color. But I guess this isnt the best way to do it?
That is the way to do it in iOS. UIView is the class which represent something to be shown on the screen. Every UI component is direct or indirect descendant of UIView. So, you should use UIView.
UIView is backed by CALayer to render the content to screen. You could also use CALayer, CAShapeLayer or other layer classes to create a border. But, I would not recommend to use CALayer just to show a border as it is simpler to use UIView with height of 1, on the top of that, you get some nice addition such as autolayout. If you use CALayer, you will have to set frame to layer at appropriate time when the view bounds change. It could also be tricky due to some intrinsic animation within CALayer.

Advice on Twitter like UIView

I have a question on some UIView stuff. I want to create a Twitter-like UIView cf image. So, how to create this type of view? Is it composed of several UIViews like 1 for the topbar and a second for the content (white one).
If yes, how to create this shadow between these views?
How to create the white arrow on top left (just under the image).
Any code sample will be appreciated. Thanks all!

It's simple UIViewController with white background, containing UITableView with one cell.
