Summary: In Xcode 8, building & running on the simulator almost instantly launched the app on the simulator. No longer in Xcode 9: the simulator seems to simulate the actual installation of the app as it would normally happen on the device. While it is more of a true simulation, this is slowing development down when doing quick change/build/runs: one now has to wait for the installation to finish (a couple of seconds) every time. Steps to Reproduce: 1. Make a change to the code of an app 2. Build 3. Run on simulator Expected Results: App launches almost instantly on simulator as it did in Xcode 8 Actual Results: Installation animation on the app icon taking a few seconds EVERY TIME. Version: Xcode 9 Notes: This worked fine in Xcode 8
