The following code is throwing this exception:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__SwiftValue renderingMode]:
unrecognized selector sent to instance 0x6000007122b0'
let helloWorld = "Hello World"
let width = helloWorld.size(withAttributes: [.font: Font.system(size: 16.0)])
print("\(width)")
Has anyone figured out why this isn't working or a potential workaround? This is happening in Swift 5 targeting iOS 13.2
The structure Font is different from the class UIFont. The following works.
let width = helloWorld.size(withAttributes: [.font: UIFont.systemFont(ofSize: 16.0)])

I am embedding a PowerBI report in IE using ExtJS .Net, but I am receiving the following console error:
"Unhandled exception at line 6, column 1859 in http://localhost:55020/scripts/powerbi.min.js
0x800a138f - JavaScript runtime error: Unable to get property 'getRandomValues' of undefined or null reference"
function getRandomValue() {
// window.msCrypto for IE
var cryptoObj = window.crypto || window.msCrypto;
var randomValueArray = new Uint32Array(1);
cryptoObj.getRandomValues(randomValueArray);
return randomValueArray[0];
}
powerbi-client version 2.10.3
getRandomValues is a method of window.msCrypto object in IE11, but it is not supported in IE9.
powerbi-client library works fine with IE11.

I'm using this code in viewdidload()
NotificationCenter.default.addObserver(self, selector: Selector(("appWillEnterForeground:")), name: NSNotification.Name.UIApplicationDidBecomeActive, object: UIApplication.shared)
that call this function
func appWillEnterForeground(notification: NSNotification!) {
// update label text here
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(true)
NotificationCenter.default.removeObserver(self)
}
but that app crash when it back to the foreground
unrecognized selector sent to instance 0x160db800
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[ appWillEnterForeground:]: unrecognized selector sent to instance 0x160db800'
appWillEnterForeground: tells the notification center to look for a method with that name, but which takes one parameter. Your implementation of the method takes no parameters and therefore isn't seen as a correct match.
Try Selector(("appWillEnterForeground").
I have just upgraded to Swift 3 and get an error on the following code that is within a UITableViewController.
The code is return segue from a form, and is intended to refresh the table inserting the new entry from the form. This worked fine on 2.2, and I have changed NSIndexPath to IndexPath
#IBAction func saveTripFormViewList(segue:UIStoryboardSegue){
trips = uiRealm.objects(Trip.self)
let indexPath = IndexPath(forRow: trips!.count - 1, inSection: 0)
tableView.insertRowsAtIndexPaths([indexPath], withRowAnimation: .Automatic)
}
The error I get is
Argument labels '(forRow:, inSection:)' do not match any available overloads
Any advice on how to resolve the error
In Swift 3 it's just IndexPath(row:section:).
FYI, IndexPath is a new value type (a struct) that does the same job as NSIndexPath (a class). (NSIndexPath's initializer has changed as well.) Also, I believe they're toll-free bridged, but don't quote me on that.
I am using cassandra-unit 3.0.0.1 from here but it is throwing dataset not found error
#Rule
public CassandraCQLUnit cassProvider = new CassandraCQLUnit(new ClassPathCQLDataSet("simple.cql","keyspaceNameToCreate"));
is there any other plugins i need to use or is it a bug in cassandra-unit?
EDITED
I have run my test in debug mode and found that the getInputDataSetLocation is returning null for me in ClassPathCQLDataSet.java
protected InputStream getInputDataSetLocation(String dataSetLocation) { //dataSetLocation: "simple.sql"
InputStream inputDataSetLocation = this.getClass().getResourceAsStream("/" + dataSetLocation); // inputDataSetLocation: null
//when i run test for cassandraunit-example app i get BufferedInputStream#924 but I am getting null here which is causing error
return inputDataSetLocation;
}
Please let me know if i am missing anything here. Thanks a ton
I am making a Website Picker App on Xcode 4.6 and there are no issues except when I try to run it I get send to the debugger with an error.
return UIApplicationMain(argc, argv, nil, NSStringFromClass([Website_PickerAppDelegate class]));
^^This is highlighted in green with Thread 1: signal SIGABRT under it.
It also has:

Can someone please tell me what is the problem ?
Thank You!
The problem probably exists because Website_PickerAppDelegate is the class name and not the variable name, unless you capitalize your variable names. It needs to be something like
return UIApplicationMain(argc, argv, nil, NSStringFromClass([pickerAppDeligateVar class]));
Of course replace pickerAppDeligateVar with the appropriate variable name and give it a go.
The error message
-[Website_PickerViewController pickerView:numberOfRowsInComponent:]: unrecognized selector sent to instance 0x75614f0
means that you did not implement the
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
method in the Website_PickerViewController that acts as data source for the picker view.
(If you think that you implemented it: Check for typing errors such as upper/lower case
letters in the method name.)
