Anyone have a workaround or fix for this?
It looks like you have an old version of UnityAds - try the latest from the Asset Store.

Error launching application on iPhone 11 Pro Max
I have this simple code:
-(NSArray< UserObject *> *)loginUsers {
return [self loginUsersForSite:nil];//Null passed to a callee that requires a non-null argument
}
-(NSArray<UserObject *> *)loginUsersForSite:(UserDBO*)aa {
}
Why do I get the "Null passed to a callee that requires a non-null argument" there? There is no nonnull here!!! What is going on?
I tried setting the parameter to (nullable UserDBO*) but then I get "Nullability specifier 'nullable' conflicts with existing specifier 'nonnull'" . I don't unederstand where the nonnull existing specifier is... This class inherits from NSObject, implements no protocol. There is no "nonnull" in the .h file
In the .h file the class was set to assume non null
NS_ASSUME_NONNULL_BEGIN
This is what caused the problem
Here is my code snippet
template <class T>
struct ClassFriendMaker
{
typedef T Type;
};
template <class T>
class Singleton
{
friend class ClassFriendMaker<T>::Type; // Problem in this line
//Other declaration
}
When compiled with CLANG, it gave me an error:
error: elaborated type refers to a typedef
friend class ClassFriendMaker<T>::Type;
^
May I know what's wrong ? Thankyou
Replace class with typename in friend declaration
friend class ClassFriendMaker<T>::Type;
friend typename ClassFriendMaker<T>::Type;
I've an objective-c function that looks like below
+ (void) invokeSortingWithClassName: (NSString*) className functionName: (NSString*) functionName closure: (id(^)(NSArray* arr))closure;
and I've to call this method from a swift class. The swift code that calls this method looks like below
SortHandler.invokeSorting(withClassName: className, functionName: functionName, closure:
{
args in
let something = unwrap(args!)
do
{
let returnValue = try closure(something as NSArray!) //this is another closure coming as a parameter in the function in which this code is written and this throws
return returnValue;
}
catch
{
throw error
}
return "-1" as! T
})
At the start of closure definition, I get this attached error
Essentially, this closure throws an error and I am not sure, how to handle this error in objective-c definition of this function. Please help me fix this error
While a closure can be declared with throws, this closure has not been declared with throws, so your closure cannot throw - this is exactly what the error message is telling you.
Since the function is declared in Objective-C, the function signature can't be changed to include throws as Objective-C doesn't know anything about Swift exceptions.
The standard way in which error handling is translated between Swift and Objective-C is for the Objective-C block to receive an &NSError parameter.
If you have the ability to change the Objective-C method signature, it should be declared as
+(void) invokeSortingWithClassName: (NSString* _Nullable) className functionName: (NSString* _Nullable) functionName closure: (id _Nullable (^_Nullable)(NSArray* _Nullable arr, NSError* _Nullable * _Nullable error))closure;
This will allow you to throw from swift with the error being received via the error parameter in Objctive-C.
If you cannot change the method signature, then you will need to catch the exception in your closure and simply return an 'error' value, such as nil
I'm working on a class that involves sending a selector as a variable to be used later. The selector is required to take one argument, a BOOL value. Executed like so:
IMP imp = [ob methodForSelector:selector];
void (*func)(id, SEL, BOOL) = (void *)imp;
func(ob, selector, YES);
If someone tries to set a selector with a variable that doesn't match a BOOL, I'd like to return an error. Is there a way, when receiving the selector that I can check whether or not its argument is a BOOL, or in general, what Class or Type of argument has been passed?
Why?
I'm setting up a quasi notification center in one of my classes so I can easily add observers and have more control over information distribution.
Look at the method signature:
NSMethodSignature * sig = [ob methodSignatureForSelector:selector];
NSAssert(0 == strcmp(#encode(BOOL), [sig getArgumentTypeAtIndex:2]),
#"Method must take a BOOL as its sole argument.");
