Xcode 8.0 builds all targets after any change to code

Question

Xcode 8 will build every target in my project after any change I make to code. This doesn't happen after I relaunch Xcode though. It usually takes some time (20-60 minutes ish) of use before it begins to build all targets after every change.

What on earth is going on? It's very annoying and kills productivity. In Preferences>General I have 'Show live issues' & 'Continue building after errors' unchecked.

Thanks, -justColbs

There are a couple known problems in Xcode 8.0 and 8.1 (technically possible before 8.0, but more likely in that release) which have been causing unnecessary full rebuilds for developers. These problems are now fixed in Xcode 8.2 beta 2. If you want to communicate with Apple about these issues, you can reference bug # 28892475. Please let us know if you still experience this issue in Xcode 8.2 beta 2 or a later release!
