Instead of having to use xcodes constraints, which I can never get to work right, is there a way to manually set where UI elements are on the screen? I noticed that if I'm on the attributes bar for the view controller, I can set simulated metrics's size to any iphone size I want.
Then I can position the UI elements on the screen where I please. When I build and run, it always mimics exactly what I set up. However, it only works for the particular size of the iphone I specified. Is there a way to do all the sizes manually without making several xcode projects?
Thanks!
There is multiple other solution that is not as good as constraints.
1) Use frame property of views to place them
2) Use size classes to do different placement for iPad iPhone etc
3) Use suggested constraints - you are placing views and than you can give XCode possibility to create constraints for you suggesting what you want from your views placement.
You're going to want to learn how to properly use constraints. The approach you're trying to do would have been okay when there was only one screen size, but now we have three different sizes of iPad, two watch sizes and four different iPhone sizes. Here's a link to a tutorial from Ray Wenderlich (he has some pretty good tutorials to get you started n a wide variety of things). https://www.raywenderlich.com/115440/auto-layout-tutorial-in-ios-9-part-1-getting-started-2
The auto layout in storyboard on Xcode 7 isn't my favorite, but when Xcode 8 comes out it provides device specific sizes for views that makes auto layout much easier. So maybe Xcode 8 will provide a better solution to your problem!

My app has a lot of image assets so adjustments I make (resizing and changing position on the screen) to my artboards that make it look good in iPhone X make it look awful in iPhone 5 or 6 or XR. The main problem seems to be reconciling different screen dimensions, rather than sizes. Is there another way besides doing a whole new storyboard for the taller X screen dimension?
We have tried auto layout but that only works for the UI elements, not image-only graphics. What we end up with is a compromise that doesn't look fantastic on either screen.
No, you can do that through Auto Layout. There are so many techniques, you can use multipliers, you can resize heights based on widths, you can make views have a percentage size of other views, possibilities are endless. You can even make custom constraints for a specific model.
You should study more about Auto Layout, it is possible to make them all look exactly like you want.
I would like to know which is the best way to make a view controller for iOS 9 swift 2 xcode 7, for different iPhone screens?
I have tried to make it with constrains but from iphone 4s to iphone 6s screens we can see wide gaps between the icons and text fields etc.
What i'm thinking is to make different view controllers for each screen (5.5inches, 4.7inches, 3.5inches) and to make my app check with which screen the user is opening the app and load the unigue view controller for this screen.
Or maybe there is a better way but im new to swift 2.0 so i'm asking for your help!
Thanks a lot for your time.
You can make a views for multiple screens using autolyout and size classes. You have proportional constraints that fit on all screens.
Proportional constraints means you can set for example view1 is 50% of screen.
These constraints fit on all screens.
Avoid excessive use of size classes (applying constraint in different size class). Try to go with proportional constraints in hAny wAny layout.
Only go for different size class if design on ipad is different then iphone. Or if you need different font sizes on different devices.

I think this depends upon what your requirement is and what you prefer.
I usually prefer the good old Springs and Struts.
They can be used by disabling auto layout and screen sizes.
Using Springs and Struts i only create a single Storyboard to manage all iPhone and iPad screen sizes without any coding effort.
No matter how complex the UI maybe, for me Springs and Struts are the best solution.
Size classes give you a more fine grain control for different sizes and orientations. Please refer Apple's documentation
As I understood your question that you want to load storyboard as size of screen of device.
I will suggest you to refer this link to load a different storyboard depending on screen size. Sorry for Objective c but hope it helps you.
Load different storyboards
In I phone 5s simulator its working fine! I have one label,one image view and one button.As you can click on the link and see the picture now so i tell you that I used my image view as a background and the label is in the middle and the button is in the lower middle so i want that to look same in all the devices. i don't know anything about constraints.I am using Xcode 6

I suggest you to take a look at this youtube tutorial. I learned how to make the constrains by watching it. The tutorial teaches how to make the similar layout as you required.

Hope this is helpful~
Autolayout is the tool used to make UI look similar across all devices, you should try to learn it if you want to continue to develop IOS apps. The concepts are pretty basic and are used throughout other languages.
This tutorial is useful if you want to create the auto layout using storyboards.
This tutorial is useful if you are making the view programmatically. I tend to use code for auto layout but it is just a preference, storyboards is fairly simple so I would suggest that. If you are going to do it in code a is to forget setting the autoresizing mask into constraints to false. You have to set this property on all the views you want to use auto layout for.
view2.setTranslatesAutoresizingMaskIntoConstraints(false)
Background ImageView
Select Image ->Pin->Uncheck Constraints to margin-> select top,bottom,left,right.
Button
Select Button-> Pin->Uncheck Constraints to margin->select bottom,left,right,Height.
label
Select label->Align->Center horizontally and Center Vertically in Container.
Pin->Width,Height.
If it is working for iPhone 5 but not another layout then this is probably happening.
There are demensions in the centre of the lower tab bar of story boards
There are screen size settings in the story board and regular*regular is the only one that is universal to all orientations and sizes of the ios device. if you set constraints while viewing in regular by compact (landscape for 5.5 inch iPhone) then those constraints will only be apply to 5.5 inch iPhones in landscape and if you tried running on a smaller iPod it would be as if you never set the constraints. the constraints for the 5.5 inch iPhone would not apply to the small iPod
if constraints were made in compact by compact and you were viewing the story board in say regular by compact then you would get an error saying that things are misplace and will not appear in the same at runtime. view the storyboard in the same dimensions that you set the constraints and you should not have an issue.
There is an option to simulate the device you want to run on specifically in storyboard and it can be say only 5.5 inch iPhones or something, whatever device.
go to paul hegarty developing iOS apps with swift on iTunes you if you want to learn more. He is a good source.
I have several custom UITextfields in my app. I started this app on Xcode 5 and ran on iphone 5 simulator. After Xcode updated to Xcode 6, I ran the app on iPhone 6 simulator. Now all the textfield positions moved up because of large screen size. I just wanted to know is there anything I could do so that the positions of textfields automatically get adjusted depending upon the iPhone models.
You need to rebuild your interface to handle the different screen sizes. In particular, you need to work with the AutoLayout feature to help determine how you want everything to scale/move/position based on multiple screen sizes. This can be done via the Storyboard (easier but sometimes frustrating) or in code (harder at first but more control later). I usually use Storyboards and it's worked great on several projects.
Do you want it centered and respecting your original layout and margins? a certain distance from the top or sides? everything scaled up appropriately? All these things can be done with AutoLayouts.

I am working on an app and have come into some graphical problems when designing my app.
First off, my app is only support by iPhone. My current storyboard is using the iPhone 5 as the screen size, so everything screws up when I try to run in iPhone 4 and 4S. Is there a way to make multiple storyboards for each different screen size? Or do you all have another solution?
Thanks!

There is a way to make different storyboards for separate screen sizes, but another way to do it is like this:
Whenever you add objects to your views, be sure to have them aligned to something (using constraints). If all items are relative to other items, then most likely the layout will be fine on all devices. Also, if you find that your controls start overlapping, then perhaps you ran out of room. In that case simply add a scroll view to your layout, and then put the controls on top of it. Then, it won't scroll on the larger screens because all controls are shown, but on smaller devices it will allow you to scroll down to see the rest of the objects.
Good luck.
There is a small button in the lower right hand corner that lets you toggle between 3.5" and 4" screen sizes so you can see how it will look on different devices. By using Auto Layout introduced in iOS 6 you can make sure to set up your constraints so that your UI looks good on both older and newer iPhones.
