Failed to chmod user/Library/Developer/CoreSimulator/Devices NO Such File Or directory

When i try to run my app in iPhone 6 simulator, i am getting following error. I am using Xcode 8.1 can any one please help me to understand this issue

I had this issue, where it would run it every time I deleted the app from the simulator, but when I tried to run it second time this error would show.

I solved it by resetting the iOS Simulator from the top bar menu.

Xcode 9.0: Hardware → Erase All Content and Settings...

Pre Xcode 9.0: Simulator → Reset Content and Settings...

I solved this with restart iOS Simulator: Hardware -> Reboot.

You can also solve this issue by just rebooting your simulator. there is no need to reset the simulator.

i have same problem and i have solved it by just rebooting simulator.

Check the Schema name and Executable file name in plistfile. both should be same.

I had this problem with an app that contained an embedded Sticker extension.

To work around it I first installed the app without the Sticker extension, I did this by clicking the Sticker.appex in the Products group and removing the app 'Target Membership' using the Inspector panel.

Once the app was installed, I could re-toggle the target membership and install the app with the Sticker extension.
