Overlapping accesses to 'data' (Xcode 10 beta, Swift 4.2)

[Yvo van Beek]

In Xcode 10 beta with Swift 4.2 there are two build errors, in URL+XCGAdditions.swift (line 26 and 64):

Overlapping accesses to 'data', but modification requires exclusive access; consider copying to a local variable

I think the issue is that you are referring to data inside of the withUnsafeMutableBytes block. The block is reading the data variable (with data.count) while it is modifying the data variable.

A potential fix would be to replace data with $0.pointee, but I'm not sure if that is just hiding the problem. Perhaps it would be better to extract the data.count into a separate variable before you enter the block and use that inside the block.

This is actually already fixed on master.
There would need to be a release done w/ cocoapods in order to update dependencies easily ?

[Bogdan Bystritskiy]

We will wait for updates for cocoapods

Any news on this?

[Carmelo Gallo]

Actually the data.count can be replaced with lenght :)

6.0.4 is now available as a pod etc. Fixes these issues (and a few more).

Hi @mithun-grmtech, you are most likely using the wrong version of XCGLogger.
If you're using Xcode 10.1, you should be using version 6.1.0 of XCGLogger, so make sure you specify that in your Podfile:

pod 'XCGLogger', '~> 6.1.0'

If you're still having issues after this, please ask a question on StackOverflow, and include the contents of your Podfile.
