Right after updating Xcode to 8.3, I started receiving this error at launch: Terminating app due to uncaught exception 'CALayerInvalidGeometry', reason: 'CALayer position contains NaN: [nan nan]'
The main view for my app has a couple of container views, one of which holds a mapView. It appears the error has to do with the map, but I can't quite make out from the message what that might be. Any thoughts would be greatly appreciated!

It seems that you are doing setPosition: using CALayer object and that CALayer object is nil. Thats why your app is crashed.
please check that CALayer is nil or not by if statement.
I figured it out. The problem stemmed from a 3rd party extension I was using for MapKit. After removing my mapView from storyboard and creating a new one programmatically, a new error pointed me to methods in the extension.

Funny thing is that this error doesn't make any sense to all the equipment. There was no error in my device (iOS 10.3.3)
so I tried running this app in Xcode 9 beta 5, iOS 11 beta 5 to get some error and appeared this assertion failure. I think There is a doubt about navigationBarItem.
Please help.
In my case I was getting an "infinite" origin for a valid UITextRange when trying to get UITextField.firstRect(). That was causing the constraint update to fail.
I would recommend to get Xcode 9 and debug your code there.
I have very limited knowledge in swift 3. My code compiles but app crashes upon launch with the following error. I have know clue what is going on or how to fix it. An help would be appreciated.

So i was doing a tutorial from Sinch! on how to Fetch and Call Contacts,
Well it loads up the Contacts just fine.
The problem is that whenever I select a Contact to call, the app crashes and Xcode shows this error on the console.
Can anyone help me with that?

It says what happened at the very top

So figure out where you're calling something that utilizes an applicationKey and figure out why it's blank :)

The UITableView works fine when I am trying to use it through Xcode6.4, but when I'm trying it through Xcode 7.1.1 it crashes. I guess it's because of the iOS versions. I am attaching the crash log. Kindly suggest what the best way to fix it is. I am quite sure that:
1) Datasource and Delegates are working fine.
2) Numberofrows and heightOfRow methods are also getting called, but it crashes before the cellForRowAtIndexPath gets called.
Here is the log:

You have an invalid indexpath. That means that either the section or the row or both is not right. If you have a table with 2 sections and 2 rows per section then indexpath 0-3 is invalid, because section 0 does not provide a row 3. Similarly, indexpath 2-1 would be invalid, because section 2 does not exist (only 0 and 1).
As for how to fix this, first double check if all required methods are called and your data is correctly initialised. Then sprinkle breakpoints around your class. Mainly where you use any kind of indexpath, and see where it tries to read from outside your data.
Learn to read crash logs. In most cases and certainly in this case, they contain all the relevant information:
2016-02-05 15:34:27.400 Autograph24[3720:87023] * Assertion failure in -[UITableViewRowData _assertValidIndexPath:allowEmptySection:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit_Sim/UIKit-3512.29.5/UITableViewRowData.m:2310
2016-02-05 15:34:27.506 Autograph24[3720:87023] * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid indexPath'
It clearly says: reason: 'Invalid indexPath'
So first hint: an invalid index path (which is a well known thing if you work with UITableViews) was involved.
Next follows the stack trace where the error ocurred. The first few stack locations are within Apple's code. Usually skip them. But occasionally, they contain interesting hints. Here a function assertValidIndexPath:allowEmptySection:. That again shows that the index path is the problem.

Here your code follows. Look at the line above and below. It says that your function [DashboardVC scrollToToday] has called the function [UITableView scrollToRowAtIndexPath:atScrollPosition:animated:]. This is where the error was triggered in your code.

This is the next interesting location. Here Apple's UIKit called your [DashboardVC viewDidLoad]. So that gives a lot of context. It happend early during the construction of you view in the viewDidLoad phase.

Combining this information I would conclude that you call [UITableView scrollToRowAtIndexPath:atScrollPosition:animated:] from within [DashboardVC viewDidLoad], which is bound to fail with any index path because the UITableView is not properly constructed at this time of the view controller's lifecycle.
Earlier iOS versions were more lenient here; but later versions are rather restrictive about what you can do before the view controller is fully constructed.
You will need to move your [UITableView scrollToRowAtIndexPath:atScrollPosition:animated:] call to either viewWillAppear: or even viewDidAppear:.
