Xcode 5 - “iOS Simulator failed to install applica

Question

Using Xcode 5 GM, anytime I switch to the 5.1, 6.0 or 6.1 simulators to test, I get the error "iOS Simulator failed to install application." When I reset the simulator it works, but this is getting very tiring.

Anybody have a permanent fix or workaround?

Answer 1

/Users/YOURUSERNAME/Library/Developer/Xcode/ --> remove all contents of this folder, then simply launch the app from Xcode.

Answer 2

Delete the old version app in your simulator (usually iOS 6.x).

Answer 3

I have different issue when getting error message “iOS Simulator failed to install application”, the reason is because I have added a property in App-Info.plist without any value. For instance, [Application Category] with no value. Thus the error will show up as well.

Answer 4

Alternatively, header over to iOS Simulator - Reset Content and Settings.

This can be easier when you have a lot of apps on the simulator and can't remember which one you're currently working on.

You need to do this for every iOS Simulator version that causes the problem.

Answer 5

if you have already developed project and you used xib to develop views then

X-Code > Inspector Selector Bar > Interface Builder Document > opens in > and change from Xcode Default(5.o) to Xcode 4.6 .

Build and Run your app it will run successfully, if it won't run again then, header over to iOS Simulator - Reset Content and Settings. delete old app from simulator then Run again.
