    Probably at least one of the constraints in the following list is one you don't want. 
    Try this: 
        (1) look at each constraint and try to figure out which you don't expect; 
        (2) find the code that added the unwanted constraint or constraints and fix it.

    "<NSLayoutConstraint:0x6000038cb890 UILayoutGuide:0x6000022d3720'UIViewSafeAreaLayoutGuide'.trailing == UIStackView:0x7fdffdc24870.trailing + 1   (active)>",

)

Will attempt to recover by breaking constraint

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.

libc++abi.dylib: terminating with uncaught exception of type NSException"

I already tried to reset and clear the costraints

this is my tableViewController code

class StrainTableViewController: UITableViewController {
    var diseasePics = [UIImage()]
    override func viewDidLoad() {
        super.viewDidLoad()
        loadPics()

        // Uncomment the following line to preserve selection between presentations
        // self.clearsSelectionOnViewWillAppear = false

        // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
        // self.navigationItem.rightBarButtonItem = self.editButtonItem
    }

    // MARK: - Table view data source

    override func numberOfSections(in tableView: UITableView) -> Int {
        // #warning Incomplete implementation, return the number of sections
        return 1
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        // #warning Incomplete implementation, return the number of rows
        return diseasePics.count
    }

    func loadPics(){
        let anxietyPic = UIImage(named: "Anxiety")
        let depressionPic = UIImage(named: "Depression")
        let arthritisPic = UIImage(named: "Arthritis")
        let crampsPic = UIImage(named: "Cramps")
        let fatiguePic = UIImage(named: "Fatigue")
        let headachePic = UIImage(named: "Headache")

        diseasePics = [anxietyPic,depressionPic, arthritisPic, crampsPic, fatiguePic,headachePic] as! [UIImage] 
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "StrainCell", for: indexPath) as! StrainTableViewCell

        let image = diseasePics[indexPath.row]
        cell.diseaseImage.image = image
        return cell
    }
}

I really don't think that the problem are the constraints, I believe there is something wrong in here

I do not see any constraint code. The issue must be in your layout from StrainCell. Try showing only one cell and with the Debug View Hierarchy and the Console log find the view with issue. — Deryck Lucian, Aug 22 '19 at 10:28
@gloria00 can you please add the error as shown in the debug output. For example have a look at this [question](https://stackoverflow.com/q/14327145/4056108). This will allow us to understand what is causing the crash. — chirag90, Aug 22 '19 at 10:32
Your app crashes because of this line: ```*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] instantiated view controller with identifier "UIViewController-lwe-wj-C4h" from storyboard "Main", but didn't get a UITableView.``` Constraints don't crush an app. — Starsky, Aug 22 '19 at 13:09

This error is due to your UITableViewController doesn't contain UITableView check your storyboard and add TableView in your UITableViewController.

and you also need to register your cell in viewDidLoad() method before calling loadPics() function like:

tableView.register(UINib(nibName: "StrainTableViewCell", bundle: nil), forCellReuseIdentifier: "StrainCell")

Tried that. My storyboard already has a tableView, also tried to add the above line but it didn't work – gloria00 Aug 23 '19 at 07:10
`*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] instantiated view controller with identifier "UIViewController-lwe-wj-C4h" from storyboard "Main", but didn't get a UITableView.' ` Check your error it is clearly saying the viewcontroller with this "UIViewController-lwe-wj-C4h" identifier doesn't have any UITableview. Kindly check your storyboard that you are assigning a write controller. – Munzareen Atique Aug 23 '19 at 12:25

Turned out the problem was the loadPics method. I initialized the pictures without using any method and it worked fine
