#### build & run
148+
149+
Using bash:
150+
$ cd examples/ios
151+
$ make run
152+
153+
In an ideal world, this will boot up, install and run the app for the first
154+
iOS simulator in your `xcrun simctl devices list`. If this fails, you can
155+
specify the simulator device UUID via:
156+
$ DEVICE_ID=${YOUR_DEVICE_ID} make run
157+
158+
If you'd like to see xcode do stuff, you can run
159+
$ open bevy_ios_example.xcodeproj/
160+
161+
which will open xcode. You then must push the zoom zoom play button and wait
162+
for the magic.
163+
164+
The Xcode build GUI will by default build the rust library for both
165+
`x86_64-apple-ios`, and `aarch64-apple-ios` which may take a while. If you'd
166+
like speed this up, you update the `IOS_TARGETS` User-Defined environment
167+
variable in the "`cargo_ios` target" to be either `x86_64-apple-ios` or
168+
`aarch64-applo-ios` depending on your goal.
169+
170+
Note: if you update this variable in Xcode, it will also change the default
171+
used for the `Makefile`.
