UINavigationController Crashes on Xcode 9

Every time I try to push a view with navigationController on my application I get the console message provided below. But if I only push the simple view controller it works fine, it happens only with navigation controller.

I'm not using a third party library to push views, I checked UIkit framework is OK, I also clean the project before building, also tried with a new view controller different from my custom view controller but the error is the same, it is only happening on new version of Xcode 9.0, on Previous version 8.0 this didn't happen.

here is an example of my code on didFinishLaunchingWithOptions

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
CustomViewController *startUpVC = [[CustomViewController alloc] init];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:startUpVC];

after use navigationcontroller sentence it crashes.

I suffered with the same issue, When we have a storyboard saved with Xcode 8 and opening in the project with Xcode 9, It happens because Xcode 9 save the document using safe area. Xib source code saved with Xcode 9:

<document type="com.apple.InterfaceBuilder3.CocoaTouch.XIB" version="3.0" toolsVersion="13196" targetRuntime="iOS.CocoaTouch" propertyAccessControl="none" useAutolayout="YES" useTraitCollections="YES" useSafeAreas="YES" colorMatched="YES">
<device id="retina4_7" orientation="portrait">
    <adaptation id="fullscreen"/>
</device>
<dependencies>
    <deployment identifier="iOS"/>
    <plugIn identifier="com.apple.InterfaceBuilder.IBCocoaTouchPlugin" version="13173"/>
    <capability name="Constraints with non-1.0 multipliers" minToolsVersion="5.1"/>
    <capability name="Safe area layout guides" minToolsVersion="9.0"/>
    <capability name="documents saved in the Xcode 8 format" minToolsVersion="8.0"/>
</dependencies>
</document>

but Xib saved with Xcode 8 is:

<document type="com.apple.InterfaceBuilder3.CocoaTouch.XIB" version="3.0" toolsVersion="12120" systemVersion="16F73" targetRuntime="iOS.CocoaTouch" propertyAccessControl="none" useAutolayout="YES" useTraitCollections="YES" colorMatched="YES">
<device id="retina4_0" orientation="portrait">
    <adaptation id="fullscreen"/>
</device>
<dependencies>
    <plugIn identifier="com.apple.InterfaceBuilder.IBCocoaTouchPlugin" version="12088"/>
    <capability name="documents saved in the Xcode 8 format" minToolsVersion="8.0"/>
</dependencies>
</document>

change the source code of storyboard accordingly.

Hope, it'll help!

Select your View Controller and then go to Editor->Embed In->Navigation Controller . Because some time if controller is not in Navigation controller hierarchy then app crash when user want to push to another controller. Hope it will help.

I get this error when I connect my right bar button item to an IBAction from the storyboard, which is quite interesting if you ask me...

I have found out that one common cause for this issue is when you try to modify the view BEFORE viewDidLoad has been called in the UINavigationController (eg. in any of the init methods).

Often in these cases it is sufficient to move any view related modifications regarding the UINavigationController to viewWillAppear (or at least to after the super-call to viewDidLoad).
