+# iOS Build
+
+## Prerequisites
+
+The build script require to be run on MacOs with XCode and the developer SDK installed.
+
+This project is tested against SDK 15.5.
+
+If you want to specify another version you need to set the environment variable below:
+
+    export SDK_VERSION=15.5
+
+You can list all the versions of the SDK installed on your Mac using the command below:
+
+    xcodebuild -showsdks
+
+## Build
+
+In the ios directory, run:
+    ./build.sh [ iPhoneOS armv7 | iPhoneOS armv7s | iPhoneOS arm64 | iPhoneSimulator i386 | iPhoneSimulator x86_64 ]
+
+Note that certain target architectures may or may not be available depending on your target SDK Version. For example, iOS 10 is the maximum deployment target for 32-bit targets.
+
+[This website](https://docs.elementscompiler.com/Platforms/Cocoa/CpuArchitectures/) can help you choose which architecture you need to target depending on your SDK version.
