When running my app on smaller screens (iPod, iPhone SE, etc.) the pod crashes in TimelineTableViewCell.swift at line 101 with the fatal error:

Thread 1: Fatal error: Can't form Range with upperBound < lowerBound file Swift/x86_64-apple-ios-simulator.swiftinterface, line 14814

This is the code starting from line 101.

let views = viewsInStackView.count <= maxNumSubviews ? viewsInStackView : Array(viewsInStackView[0..<maxNumSubviews]) views.forEach { view in view.translatesAutoresizingMaskIntoConstraints = false view.addConstraint(NSLayoutConstraint(item: view, attribute: NSLayoutConstraint.Attribute.width, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.height, multiplier: 1, constant: 0)) view.contentMode = .scaleAspectFill view.clipsToBounds = true stackView.addArrangedSubview(view) }

viewsInStackView at this stage are 0, while the maxNumSubviews are -1. Hence the crash.

This is only seen on some devices, not all. Hence it is difficult to spot or reproduce. I have seen this on some iPhone 5s, iPhone SE and iPod Touch (7th Gen) so far.

Need a resolution really soon as many of my users can't use my app anymore.

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle </Users/irfanpule/Library/Developer/CoreSimulator/Devices/77500ABE-FA84-4DF7-A658-0AC1E134A454/data/Containers/Bundle/Application/CCA3C281-0E57-4313-8B0E-95B53C6D0276/xxxxxx.app/Frameworks/TimelineTableViewCell.framework> (loaded)' with name 'TimelineTableViewCell''

I am using Xcode 11, Swift 5

Hello, I would like to ask about separators. If I want to use separator between cells there is a problem with right margin. The separator ends in the edge of display (check photo). However left side is OK. Is there any way, how to edit properties of this separator?

Hello, I am trying to use this library, unfortunately it doesn't work. I am beginner in swift, so I suppose, it will be some silly mistake. I have create view with tableview and swift file TimelineViewController. I have copied the code from your demo project (from TimelineTableViewController). When I am trying to run it on simulator, I get error

Could not load NIB in bundle: 'NSBundle </Users/silversurfer/Library/Developer/CoreSimulator/Devices/17FBAA4A-F887-4D71-9CD6-41D3979F4A0A/data/Containers/Bundle/Application/14C5257D-7D3E-40CA-9D46-C7E16C0DACF8/Time.app/Frameworks/TimelineTableViewCell.framework> (loaded)' with name 'TimelineTableViewCell''

Could someone help me, where I made a mistake? Thank you in advance

I want to customize the custom cell. For example, I want to add a location icon and location label in some cells. Also, I need a button in every cells. Can you help?

Configured the cell, but when the table view scrolls and dequeueReusableCell is called, then the bubble layer takes the full width of the cell instead.

There were a few metrics issues when changing the size of the timeline point and the timeline itself.

The project is now able to cope with a variety of modifications including different label margins and points inside the timeline. There are no changes to be made to the existing example project. Here is one such example of what can be done with the upgrade:

Here is the code that creates this timeline:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "TimelineTableViewCell", for: indexPath) as! TimelineTableViewCell
    
    guard let sectionData = data[indexPath.section] else {
        return cell
    }
    
    let data = sectionData[indexPath.row]
    let situation = data["situation"]!
    let startTime = data["startTime"]!
    var endTime = "PRESENT"
    if (indexPath.row > 0) {
        endTime = sectionData[indexPath.row - 1]["startTime"]!
    }
    
    let title = situation
    let iconName = "ic-" + title.replacingOccurrences(of: " ", with: "-").lowercased()
    let timelineColor = UIColor(red: 1, green: 1, blue: 1, alpha: 1)
    var timelineFrontColor = timelineColor
    var timelineBackColor = timelineColor
    var timelinePointColor = UIColor.black
    if (indexPath.row == 0) {
        timelineFrontColor = UIColor.clear
        if (indexPath.section == 0) {
            timelinePointColor = UIColor(red: 0.959, green: 0.459, blue: 0.603, alpha: 1)
        }
    }
    if (indexPath.row == sectionData.count - 1) {
        timelineBackColor = UIColor.clear
    }
    cell.timelinePoint = TimelinePoint(diameter: 12, lineWidth: 1, color: timelinePointColor, filled: true)
    cell.timeline.frontColor = timelineFrontColor
    cell.timeline.backColor = timelineBackColor
    cell.timeline.width = 20
    cell.timeline.leftMargin = tableView.bounds.width * 0.27
    
    cell.titleLabel.text = title.uppercased()
    cell.titleLabel.font = UIFont(name: "Avenir Next", size: 20)
    cell.titleLabel.textColor = UIColor.white
    
    cell.descriptionLabel.text = "\(startTime) - \(endTime)"
    cell.descriptionMargin.constant = 2
    
    cell.illustrationSize.constant = 28
    cell.illustrationImageView.image = UIImage(named: iconName)
    
    cell.bubbleEnabled = false
    
    return cell
}

HI , Just checking whether it is possible to support title and description on both sides of line, based on some setting .Please share your thoughts , I want the line to be on the center and title and description to be shown on both sides alternatively.

Hi, thanks first of all for the library. I wanted to ask you if there's a way to customise the cell in the way i will show you in the attached pic. I just want to relocate the description and title, and also add an image in between the timeline and the written text.

Not sure how to reproduce this, but for some reason maxNumSubviews ends up being -1, which causes a crash in TimelineTableViewCell on this line:

let views = viewsInStackView.count <= maxNumSubviews ? viewsInStackView : Array(viewsInStackView[0..<maxNumSubviews])

Just curious if anyone else has had this problem? I'm working on a fork on my end, so it may be caused by that. However refactoring this line to be a bit cleaner couldn't hurt
