Java ThreadLocal is used to create thread local variables. It is known that threads of an Object share it’s variables, so the variable is not thread safe. We can use synchronization for thread safety but if we want to avoid synchronization,ThreadLocal allows us to create variables which are local to...

where clause By adding a where clause you can restrict the iterations to ones that satisfy the given condition. for i in 0..<5 where i % 2 == 0 { print(i) } // 0 // 2 // 4 let names = ["James", "Emily", "Miles"] for name in names where name.c...

If you need to call an Objective-C method from C code, you have two ways: using objc_msgSend, or obtaining the IMP (method implementation function pointer) and calling that. #import <objc/objc.h> @implementation Example - (double)negate:(double)value { return -value; } - (doubl...
