Autolayout issue after updating to Swift 2.0

Question

After downloading Xcode 7.0 and migrating to Swift 2.0, i am getting the following error.

Attempt to add this NSLayoutConstraint to an engine in which it already exists. This can cause engine corruption. Break on void _NSLayoutConstraintRedundantAdd() to debug. This will be logged only once. This may break in the future.

Answer 1

Seems that for few people it got fixed by updating to Xcode 7 beta 5
