Why is my block declaration giving me an incompatible pointer error?

I'm declaring a block like this:

void (^callback)(NSString *_accessToken) = ^{
  // do something interesting with _accessToken
}

but XCode keeps telling me 

Incompatible block pointer types initializing void(^__strong)(NSString *__strong)
with an expression of type void (^)(void)

What am I doing wrong?

void (^callback)(NSString *) = ^(NSString *_accessToken){
