I am using https://github.com/Ramotion/folding-cell library into my Swift 3.0 projects. It works nice without any editing or changing on storyboard/auto layout changing.
I faced some issues when tried to:
Add few IBOUTLET (in DemoCell.swift)
Add Data to them (in DemoCell's didSet() method)
Now the view is blank. But i can scroll the tableview(it is just not showing), can click and can see folded cell perfectly.
I tried to add constrains as it given in documentation. I get fatal crash.
I am using Xcode 8, swift 3.0. This is happen always even when i download the fresh source code and add new uilabel or anything change on storyboard.
Does anybody tried this library recently ?

When click in the cell, Other cell is hidden.But clickable.

It was an issue with the library. Now its solved.

While compiling a couple of projects with XCode 12 (beta 5 is the latest version at the moment) and running them on iOS14, I've noticed that UIButton, UITextField, and many other selectable objects are not responding to user input when inside of a UITableViewCell.
In some cases, it is possible to work around the issue by bringing the object to the front (object.bringToFront()), but this is not working for all the cases I'm facing. I've also noticed an empty view (layer) on top of the components of the cell when I use the "Debug View Hierarchy" Tool. This view is not present on XCode 11 builds. Is this some new cell configuration that I'm missing? Is there a standard way of disabling this behavior or will I have to be hacky to fix this?
PS: The issues were not present on the same projects when compiled with XCode 11 (or previous), even when running on iOS14.
All the select response issue may caused by adding subview on UITableviewCell. The right way is add on UITableViewCell.contentView, check it first.
I am working on an existing iOS Project in Xcode 10.2.1 on macOS 10.14.4. The uses mainly Objectiv-C but also some Swift Pods (v. 1.5.2). Recently I have also added the first Swift based ViewController using Swift 5.
The Problem:
When working on the XIB file of this Swift bases ViewController after a short time the following error message is shown in the Xcode sidebar:
IB Designables: Failed to render and update auto layout status for
ViewXYZ (abc-de-123): The agent crashed
As soon as there error occur no changes in the Interface Builder (added view, changed colors, text, etc.) are shown anymore. When I re-open the XIB file it only show grey view placeholders instead of the real content.
The problem can only be solved by re-starting Xcode but when working on the XIB again it shows up after again after just a few moment.
Things that did NOT work
Since the problem is realted to IB Designabales I checked these first. Within the ViewController I am using two different custom views which are implemented in Objective-C and marked as IB_DESIGNABLE.
These views have not been changed recently and it was never a problem to use them before. Removing all custom code from these views did not change the problem. Thus there seems to be nothing wrong with the implementation.
I found other topics dealing with similar issues, but none of the different solutions worked for me:
Re-starting the Mac, re-starting Xcode, cleaning the build folder or deleting ~/Library/Developer/Xcode/DerivedData does NOT solve the problem
Adding this code to the pod file does NOT solve the problem
Adding all UIView constructors to the views as proposed here does NOT solve the problem.
Xcode shows that the designables are up to date and does NOT offer a debug button (as shown here)
The views do not have orphant outlets
Re-creating the XIB from scratch let to the same issue
Not using the Bundle or other device specific code within the custom views did NOT solve the problem. As described before I removed ALL custom code from the classes so that they where simple UIView subclasses without any changes.
So far nothing I tried had any effect. However, most answers I found are quite old. Are there are any new proposals to solve this issue?
In Xcode 7, I was able to add a UILabel only to the Regular/Regular size-class. I simply selected w: Regular h:Regular below the storyboard and added it to my controller using drag 'n' drop. Once I switched to another size-class, the element was shown as inactive in the document outline on the left. Everything fine.
Now the same approach doesn't seem to work. When I switch to another size-class after the label was added to regular/regular, the UILabel is still active in the document outline and shown when the app is running (on an iPhone for example).
Any pointers or hints more than appreciated! Release notes don't offer any clue. Doesn't look like a wanted behaviour that was mentioned anywhere.
I have been working on this app for months now and from as far back as I can remember I have never had an issue with segues. The code is unchanged in terms of calling performSegueWithIdentifier but since my recent update to Xcode 7 and iOS 9 I have not been able to tack this issue.
I have tried:
Deleting button and creating new button w/ segue link
Using a direct segue from button to view, without the use of performSegueWithIdentifier
Connecting button to new blank viewController
When I press the button, no initial load functions are called on the destination VC (Ex: ViewDidLoad, ViewWillAppear, etc). When I connect it to a blank view, the segue works fine with the same code in place.
Since the code never stops, or breaks, and just seems to "freeze" in place while still running on Xcode I can't seem to even narrow this down to whats causing the issue. I have a similar segue that is also called from another button on the same ViewController that has no issues whatsoever.
Any thoughts on the matter are greatly appreciated!
EDIT: I have narrowed the issue down to the UITextView's causing the problem. Once the Text Views were removed the page loads fine via segue. I wonder what changed between iOS 8 and iOS 9 in terms of UITextView as I will have to remove the text views and completely re add new text views.
So basically the segue was freezing because of the UITextView's I was using in the destinationViewController. The following fixed the issue:
Delete all UITextView's
Add new UITextView's
you must leave the default lorem imposed text and change this programmatically in the viewDidLoad()
This was the fix for me, and from the research I have done on the issue it seems this is a bug in iOS 9 and Xcode 7.
Cheers!
NOTE: Removing the text in the UITextView (or making it longer then ~12 characters) is sufficient to work around it, no need to delete and recreate them. This is fixed in Xcode 7.1.1 and later.
I ran into the same issue and the fixes in this post (Xcode 7 crash: [NSLocalizableString length] 30000) solved the issue for me.
The first is to enable a localisation other than the base for the storyboard (see https://stackoverflow.com/a/32688815/3718974)
The second is to turn off the base localisation (see https://stackoverflow.com/a/32719247/3718974)
I think I have the same problem: I have a UITabelView with cells created from a nib file, when a user tap a cell this method is called:
and when I have the following method prepareForSegue:: the application crashes:
if I delete the line 129 Everything is ok , the method prepareForSegue:: open the right view and the label contactName is shown with its default text.
If I modify the method as follows prepareForSegue:: get exactly what you expect, without having any type of error:
let me know if you also get the same result
Any one who is facing this issue, i solved it by turning off the "Optimize rendering for windows scale" option in Debug of simulator window. I already had tried all of the above answers but could not solve the issue.
In the method in the first viewController where you activate the segue, do you have beginIgnoringInteractionEvents anywhere? If so the screen you segue to will be frozen and will ignore interaction events like you describe. If this is the case you can fix this by adding an endIgnoringInteractionEvents method before your segue method:
UIApplication.sharedApplication().endIgnoringInteractionEvents()
self.performSegueWithIdentifier("editItemToMyGearSegue", sender: self)
I realize this is an old topic, but appears to be still relevant. I was facing the same problem in Xcode 9, iOS11. My UITextViews are embedded inside UITableViewCells. Same symptoms as described here. The tricks with default text and placeholders did nothing for me, but I solved it by turning off the scrolling indicators for the text view in the xib. They were on by default, I guess, though unused.
Edit: this is probably an important detail... the views that were hanging all had an image NSTextAttachment in the attributed string of the text view. I think the image was wider than the available table cell content. With scrolling turned off, they appear to downscale.
I have a custom button that is a subclassed UIButton. When I try to drag it into a UIScrollView in IB Xcode immediately crashes. What gives?
I have this custom button working inside a UIScrollView in at least one other location in my app. Any ideas?
UPDATE:
Uncheck "Use Autolayout" in the File Inspector fixes this problem. See answer below.

I could crash several Java editor like this. The problem it was in my custom component code:
I have added code, which the designer ( Interface builder) have executed to show my component.
Take extra care at init, viewDidLoad methods in your Button code.
Do not know exactly, But once the same kind of issue happened with me.
My problem was that some of my drawing methods were being called recursively, causing the Xcode to crash. I handled those recursive calls and issue got fixed.
SOLUTION: Uncheck "Use Autolayout" in the File Inspector
Thanks to #BornCoder I decided to try running this on my laptop running Xcode 4.4. When I tried to build I got an error saying this version of Xcode doesn't support Autolayout. I didn't intend to use Autolayout, it looks like Xcode 4.5 does automatically. Unchecking the box fixed it.
