+# assimp for iOS
+(deployment target 6.0+, 32/64bit)
+
+Builds assimp libraries for several iOS CPU architectures at once, and outputs a fat binary from the result.
+
+Run the **build.sh** script from the ```./port/iOS/``` directory. See **./build.sh --help** for information about command line options. 
+
+```bash
+shadeds-Mac:iOS arul$ ./build.sh --help
+[!] ./build.sh - assimp iOS build script
+ - don't build fat library (--no-fat)
+ - supported architectures(--archs): armv7, armv7s, arm64, i386, x86_64
+ - supported C++ STD libs.(--stdlib): libc++, libstdc++
+```
+Example:
+```bash
+cd ./port/iOS/
+./build.sh --stdlib=libc++ --archs="armv7 arm64 i386"
+```
+Supported architectures/devices:
+
+### Simulator
+- i386
+- x86_64
+ 
+### Device
+- ~~ARMv6 (dropped after iOS 6.0)~~
+- ARMv7
+- ARMv7-s
+- ARM64
+
+### Building with older iOS SDK versions
+The script should work out of the box for the iOS 8.x SDKs and probably newer releases as well.
+If you are using SDK version 7.x or older, you need to specify the exact SDK version inside **build.sh**, for example:
+```
+IOS_SDK_VERSION=7.1
+```
+### Optimization
+By default, no compiler optimizations are specified inside the build script. For an optimized build, add the corresponding flags to the CFLAGS definition inside **build.sh**.
