swift - RemoveAtIndex crashes playground -



swift - RemoveAtIndex crashes playground -

i'm trying remove character string using removeatindex func of string. crashes playground.

here total code:

let string = "some string" allow start = advance(string.startindex, 2) allow x = string.removeatindex(start)

you've declared string let makes immutable. since can phone call removeatindex on mutable string, can prepare declaring string var instead:

var string = "some string" allow start = advance(string.startindex, 2) allow x = string.removeatindex(start)

note: above works in xcode 6.1, crashes compiler in xcode 6.0.

for xcode 6.0, using global removeatindex function instead works:

var string = "some string" allow start = advance(string.startindex, 2) allow x = removeatindex(&string, start)
