Different standard Aqua space in ios 7 and 8 - ios

I'm using Xcode 7 beta 4, Mac OSX 10.10. My app's deployment target is iOS 7.0.
I know that standard Aqua space is 20 between a view and its superview. But when I design storyboard for iOS 7, I must use 8, like this:
and it looks fine (above constraints is for search bar). When I run iOS 8 simulator, it appears like this:
So I must use right value is 20. But using 20 will cut off subview in iOS 7.
Anyone know if this is a bug or is there anything different between iOS 7 and 8? This happens with all simulators and real devices too.

Xcode 14 and iOS 5.5 simulators

After updating to Xcode 14 with iOS 16, I'm not seeing any 5.5 devices - makes sense, as Xcode simulators only seem to support one iOS, and none of the 5.5 devices (for instance iPhone 8 Plus) run iOS 16.
However, 5.5 screenshots are still mandatory for the App store. So how do I create these screenshots? The solutions I can think of are these
Using physical 5.5 device like iPhone 8 Plus (I don't have one)
Downgrade Xcode to version 13 in order to support iOS 15. I would very much like to avoid this, besides some of my Mac setup is Virtual and I am not in control of the Xcode version)
Download simulators
Go to Window
Select `Devices and Simulators
Click on the plus button in the bottom left corner.
Click on OS Version dropdown
Select Download more simulator runtimes
Click on the plus button in the bottom left corner.
Select iOS
Select the desired iOS version and wait for the download.
Now, you can create a desired simulator with the desired iOS.
Remember, you can generate your screenshots based on the device size! and no need for specific simulator by the way.

iOS 11 has different autolayout result?

I'm using storyboards in this project. I have been searching for the culprit of this layout bug (see photo) and wasn't able to find one. Here are some more detailed information.
When debugging the app using my iPhone 7plus iOS 11, I'm using the Xcode 9.0 Beta 2.
iOS version of the iPhone 7plus is iOS 11 Beta 9. As of writing, I'm installing the Beta 10 of the iOS 11.
I have a side menu library that has a layout bug in my iPhone 7plus (same OS version) too! But when the app is downloaded from the TestFlight or App Store, that layout bug never appears, but in this particular case, the view stays under the tabBar.
Layout is perfect in my two devices below iOS 11. It is perfect too in iPhone 7plus simulator WITH iOS 10. As of writing, I'm building the project to iPhone 7plus simulator WITH iOS 11.
I have tried toggling everything in the Interface Builder like under opaque bars, etc...
I did add some different colors to some of my views in the storyboard for easier debugging of views using Xcode. And indeed that in iOS 11, the view goes underneath the tabBar while in iOS 10, it does not.
What could be the issue here?
UPDATE:
Think of the view in the photo as a plain UIView. No scrollView, no tableView. Just a UIView, nothing special, not scrollable.
Xcode 9.0 Beta 2's iPhone7plus simulator has a perfect layout.
I have updated my iPhone7plus phone to iOS 11 Beta 10, and layout is still the same.

App fonts changed when running from Xcode 8

I have designed my storyboard in Xcode 7 and it's looking fine across all devices. I set the fonts from Interface Builder but when I run the app from Xcode 8 beta in iOS 9.x, the button's and label's fonts are changed automatically. Is it a bug in Xcode 8 beta? Also, is there any way to fix this issue without changing every components fonts manually?
I have the same issue in Xcode 8 release with iOS 10. In the app built for iOS 10 in Xcode 8 running on iOS 9.3 both simulator and on a real device 6plus the font size decreases in size. Oddly enough running on an iPad
Running the same build in iOS 10 everything is fine.
This is a iPhone app, not universal.
[Edit] - If I check Check the "Selectable" checkbox in the xib attribute inspector the problem goes away. This is for a read-only UITextView.
Interesting.

How to use iOS Simulator 7 \ XCode 5 to test pre-iOS 7 UI (without upgrading the app for iOS 7)

Compiling my app on XCode 4.6.3 and running it on iOS 7 works great.
Compiling my app on XCode 5 and running it on iOS 7 results a big UI mess I don't want to handle right now. (iOS 7 pickers, tabbars, tableviews etc')
Goal:
I want to be able to use XCode 5 and test my app on the iOS 7 simulator but still use the iOS 6 and lower UI and feel.
Reason:
I don't want to redesign my app to iOS 7 but I do want to make sure it runs fine on iOS 7 using XCode 5 iOS 7 simulator.
Is there a quick toggle on XCode 5 to force everything to stay the same?
Is doing something like using iOS 6 Base SDK in XCode 5 acceptable or a bit too much hacky?
Edit:
Using iOS 6 SDK doesn't help. You'll still get the iOS 7 look on your app, just more buggy.
This is the scenario:
Your app works fine on iOS 6 and lower
You want to test your app on iOS 7
If you have iOS 7 on your device you'll need XCode 5 in order to test it on it
If you want to test it on the iOS 7 simulator you'll need to install XCode 5 for it
Compiling your working app on XCode 5 will break all hell loose and will force you to redesign your app at least for iOS 7
The solutions suggested here so far will help you to see how your app will look like on iOS 7 but will not keep your iOS 6 and lower look on iOS 7.
Best solution I've found so far:
Update your current XCode to XCode 5
Download XCode 4.6.3 from here
Install it in a different location and Change the name of the app to XCode4 in order to differentiate between the two.
Find your XCode 5 app icon, right click it and select "Show Package Contents"
Locate the folder MacOS and move the xcode file outside of its
folder. Those last two steps are to prevent you accidentally opening a
project with XCode 5. An alternative is to change the default "Open With" app
but for some reason that didn't work
for me plus I wanted to be extra sure after I had one project opening with XCode 5
and the StoryBoard changed to be compatible to XCode 5 only. *
Open XCode 4.6.3 and run your project. In your simulator menu you
should now See iOS 7. Even if in XCode top bar you'll see AppName->iPhone
6.1 Simulator , selecting iOS 7 on the simulator will run your app in iOS 7 and keep everything the same.
After the above you'll have two versions of iOS simulator. Version 6 and version 7 that contains iOS 7 Simulator.
Step 5:
COPY iPhoneSimulator6.1.sdk
FROM
<YOUR XCode4 path>/Xcode4.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/
TO
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/
and set your base target to iOS6.1 (It will be listed after copying/pasting from xcode4) and
You cannot do this on the iOS 7 Simulator. You can do it in the iOS 6 Simulator (running under Xcode 5) and on the device (running iOS 7 as long as you build with the iOS 6 SDK). But there is no iOS 6 compatibility mode in the iOS 7 Simulator.
Note that iOS 6 compatibility mode is not a perfect replication of iOS 6. There are still various behavioral differences that you will likely have to test for and deal with. But the basic UI components are what you expect.
EDIT - Note that it is not possible to force an app to use the iOS 6 interface on an iOS 7 device using Xcode 5 (unless you make custom graphics). It is also not a good design approach. Users on iOS 7 expect a certain UI style, that's why they updated; so give it to them, don't force them back into an older interface.
If you really, really need the pre-iOS-7 interface, you can download a copy of Xcode 4 and build with that. However, starting February 1, 2014 Apple will stop accepting apps built with anything earlier than Xcode 5.0 (I think I saw something about that in the iOS 7 dev docs, but can't find the reference again).
Keeping the iOS 6 UI in your app, but building for iOS 7 is fairly straightforward. Make sure that you've set your Deployment Target as iOS 6.1 or earlier. Your Base SDK can still be set as iOS 7 though. Now, just follow the instructions below for each of your interface files:
Open your storyboard file or XIB file
Open the Utilities Panel on the right side.
Click on The File Inspector Tab. You should now see something like this:
Next go to the Interface Build Document Section and change the Builds For setting to iOS 6.0 and Later or whatever version you need.
Then change the View As setting to iOS 6.1 or earlier:
Xcode will prompt you, just confirm that you want to convert to the older UI.
Make sure to run your project in the iOS 6 Simulator. Otherwise, the iOS 7 Simulator will override it's own iOS 7 UI style. To download the iOS 6 Simulator, go to the Xcode Menu Bar. Select Xcode, Preferences. Then click on the Downloads tab. Finally, click on the Simulator(s) you need to download:
Then Run your app on the iOS 6 simulator:
Unfortunately, even disabling the iOS 7 UI in Xcode does not override it on the device / simulator. Unless you design custom UI elements, there isn't a way to maintain your iOS 6 UI on iOS 7. But as I showed you, you can continue to edit it in iOS 6 and build for iOS 6.
Linking the 6.1 SDK into Xcode 5 as described in the other answers is one step. However this still doesn't solve the problem that running on iOS 7 new UI elements are taken, view controllers are made full-size etc.
As described in this answer it is also required to switch the UI into legacy mode on iOS 7:
// put in main.m
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:#"UIUseLegacyUI"];
[[NSUserDefaults standardUserDefaults] synchronize];
Beware: This is an undocumented key and not recommended for App Store builds!
Also there are subtle differences to a version built using Xcode 4.6. For instance, transparent navigation bars behave differently (causing the view to be full-size).
However, since Xcode 4.6.3 crashes on Mavericks (at least for me, see rdar://15318883), this is at least a solution to continue using Xcode 5 for debugging.
Update: the crash of Xcode 4.6.3 on Mavericks only occurs when using LLDB. When switching back to GDB it works.
Contrary to my comments, I could actually follow the steps mentioned in the link.
What I tried was nothing sort of hacky:
Open XCode 4.6 app package (I have it still installed)
Go to Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs folder.
Copy iPhoneOS6.1.sdk folder.
Open XCode 5 app package.
Go to same Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs folder.
Paste.
I could then see iOS 6.1 as an option to base off my iOS project under Build Settings->Base SDKs.
However, even after doing this when I ran the app under iOS 7 simulator, I could sense no visual difference - all was rendered in default iOS 7 style - borderless buttons and bars.
No change after resetting simulator.
No change after changing storyboard version too.
So this again seems to confirm my assertion that this isn't possible.
If anyone tried it, I want to know.
I think that the only way to show iOS 6 controls on XCode 5 (and iOS7 Simulator) is to set the Base SDK of your Target to iOS 6.1(6.0).
You should copy the old sdk to XCode 5 like Nirav described and restart the XCode to make it visible under Base SDK selection.
My guess is that it didn't work for Nirav because he changed the settings of the project and in his case they have been dis-synchronized from settings of the target. So make sure that Base SDK for your target is iOS 6.0. Then it should work (at least it does for me).
This will give you a preview of how the app will look in iOS 6 using Xcode 5.
I saw this on a WWDC Video.
406 - taking control autolayout xcode 5 (about 32 mins in)
Using, the preview function within the storyboard.
This will allow you to pick between how it will look on iOS 7 and iOS 6.
The video shows a cool (almost hidden) feature of xcode that allows you to see, both previews of iOS6 and iOS7 at the same time, splitting up Xcode into 3 separate views
I'd like to add that while you may not be able to do it in the simulator, you can run your apps in compatibility mode on an actual device that has iOS 7.
Wow, this is a real mess. Thanks, Apple [*]
I got this (this: XCode 5 building iOS 6 apps) working for me, but I had several XIB's that were messed up, and it took a combination of several of the above steps to get it working.
1) Setup XCode 5 with iOS 6 base sdk
#Sha has good steps for that:
How to use iOS Simulator 7 \ XCode 5 to test pre-iOS 7 UI (without upgrading the app for iOS 7)
2) Go through each XIB and set it for XCode 4.6 mode
#RazorSharps post has good steps:
How to use iOS Simulator 7 \ XCode 5 to test pre-iOS 7 UI (without upgrading the app for iOS 7)
I'm not sure this was 100% required, but I did it and it works. (Perhaps I'll go back later and try without this, when I'm not still fuming).
3) Find any Navigation Controllers in XIB (or code) that may be set to Translucent, set them to Opaque
This was the trick for me. I had a root XIB that defined the Navigation Bar as Black Translucent, but all the XIB's that loaded overrode with their own appearance.
In 'real iOS 6' the controllers setting would override this (that is, the navbar would appear as opaque), but in iOS 6 Compatibility Mode on iOS 7 it wouldn't (that is, it would have an iOS 6 appearance, but be transparent, and mess up view layout).
#appledevtools: We appreciate your hard work, this is tough to get right. But here's a suggestion: When upgrading an existing project to XCode 5, IB xib's should be left in XCode 4.6 mode. Let the Editor > Validate Settings code offer to upgrade the settings, with a reasonable warning of the implications. Don't do this automatically & silently :-) Also, please find & fix why the navbar style changed in iOS 6 compatibility mode.
Good news is that we can set the base sdk to iOS 6.1 with XCode 5 now(in my case, it's Version 5.0.1 (5A2053)), and test & debug our pre-iOS7 designed app on iOS 7 simulator now.
For those who don't know how to set base sdk to iOS 6.1 for XCode, this link might be a guide.
Everything seems to work fine, the same pre-iOS7 design look & feel, except some os provided controls like ActionSheet look & behavior in the iOS 7 way.
BTW, I've upgrade my mac os to maverick yesterday, not sure whether this is an affect factor.
This worked for me but the explanation here needs cleaning up and detailing. If still desired, let me know and I will go into more detail.
It follows on from this answer
In addition to copying the iPhoneOS6.1.sdk folder, you also need to download the iOS 6.1 simulator (the proper way or copy it from an older installation of Xcode)
Then, make a duplicate of the iOS 7 simulator and replace it's plist with the 6.1 simulator's plist
Restart Xcode
You will then see two iOS 7 simulator options for each device option. One will be the normal iOS 7 simulator. The other will run your 6.1 SDK builds on the 7 simulator
WARNING You may not be able to remove the dummy simulator from Xcode's drop-down list afterwards (I haven't tried. It stuck around after I removed the dummy simulator folder)
Set deployment target to iOS 7.0 from deployment info. For that tap on project name and on first screen you will see deployment info... Change deployment target to 7.0. After that quit simulator, build and run app again.

iOS version specific Default.png?

Now that iOS 6 has come out and tweaked some control appearances, my Default.png family no longer matches the updated appearances.
If I update the appearance for iOS 6, however, the Default.png family will no longer match iOS 5.
Is there a way to provide different launch images for iOS 5 vs iOS 6?
Adding Default-568h#2x.png does not fix this problem; the problem is that Default.png and Default#2x.png must either show iOS 5 or iOS 6 screens, and they do not look the same.
I noticed in one of my apps that there was a small difference in position of one of the standard control types (captured in my launch image) between iOS 5 and iOS 6. I chose to use the new iOS 6 screenshot as the launch image, even though that causes a slight visual shift when launched on iOS 5. Virtually everybody will upgrade, so I'm not really concerned about the shift only appearing on iOS 5.
iOS 6's launch image is named "Default-568h#2x.png"
