Array-Exchange array element display error: Also accessed, but modifications require exclusive access

October 10, 2021By Simo Swift

I want to swap my array elements:

swap(&(self.profileImages[0]), &( self.profileImages[2]))

But I get this error:

Simultaneous accesses to 0x102944a80, but modification requires exclusive access

After a lot of searches: as described by Whats-new-in-Swift-4, I found that in swift4 I should use this code:

self.profileImages.swapAt(0, 2)
