nil is the literal null value for Objective-C objects, corresponding to the abstract type id or any Objective-C type declared via @interface. For instance: Nil is the literal null value for Objective-C classes, corresponding to the type Class. Since most code doesn’t need variables to reference classes, its use is not common.

In C99 the available basic integer types (the ones without _t) were deemed insufficient, because their actual sizes may vary across different systems. So, the C99 standard includes definitions of several new integer types to enhance the portability of programs. The new types are especially useful in embedded environments. All of the new types are … Read more

EXC_CORPSE_NOTIFY is irrelevant. The important information is in the Exception Type (EXC_CRASH (SIGABRT)) and the backtrace. A crash in -[__NSArrayM insertObject:atIndex:] usually occurs when you are attempting to insert a nil object into an NSMutableArray. I’m not sure what LotumMobStatLogManager is, as you haven’t provided the relevant source code. If that is an external dependency, I would reach out to the developers with … Read more
75 duplicate symbols for architecture x86_64 Means that you have loaded same functions twice. As the issue disappear after removing -ObjC from Other Linker Flags, this means that this option result that functions loads twice: from Technical Q&A This flag causes the linker to load every object file in the library that defines an Objective-C … Read more
